Overview of the Authentication and Authorization Web Services

The

SiteMinder

authorization and authentication web services are part of the

Access Gateway

installation. You can enable or disable them individually.

The following video gives an overview of the feature and how to use it:

This content is not loading because you've chosen to block "Targeting" cookies on this website, which are required for this content to be displayed. You can adjust this restriction on this site by following these steps:

  • Open Cookie Settings
  • Select "Targeting Cookies" from the left side
  • Toggle the switch on the right
  • Click on "Confirm My Choices"

The web services configuration process presupposes configuration of the following

SiteMinder

objects:

  • One or more agents to protect target applications against which callers authenticate

  • Realms, user directories, policies, and responses that are required for authentication and authorization

You can use the authentication and authorization web services to support an application that is not otherwise protected. A free-standing application on a mobile phone, for example, can authenticate a user when the appropriate

SiteMinder

objects are available.

These web services support the SOAP 1.2 protocol and the HTTP-based RESTful architectureusing the POST method. The authentication and authorization web services provide the following functionality:

  • login -- Authenticates and returns a session token when the authentication is successful.

    If the Enable User Tracking option is enabled, the response contains an identity token additionally.

  • blogin -- Authenticates and verifies whether the login is successful; does not return a session token.

  • logout -- Logs out the user or group of users.

  • authorize -- Returns an authorization status message and a refreshed session token.

The response to a request of an operation is dependent on the corresponding

SiteMinder

generated headers. If a resource is protected with the Anonymous authentication scheme, the response does not contain a session token but contains an identity token. The identity token can be used in the subsequent authorization request instead of a session token.

An authentication request includes the following parameters:

  • appId

  • resource string

  • action

  • user credentials

The appId references a user-defined logical name for the location of a hierarchy of resources, not a

SiteMinder

Application object. Internally, the appId maps to an agent.

SiteMinder

uses the agent name to determine the realm. The realm, the resource string, and user credentials are enough to authenticate the user.

An authorization request is simpler than an authentication request. The authorization request includes an appId, resource path, action, and session token, obtained from the login response. The web service validates the token and determines whether to grant access to the specified resource.

Configure the Web Services

By default, the web services feature is installed when you install or upgrade to

Access Gateway

.

To configure the web services, perform the following steps:

  1. Create anACOfor the web services through AdministrativeUI.

  2. Mitigate theDTD external entity injectionin the web services.

  3. Protect the web services.

  4. Enable the web services through Administrative UI.

  5. (Optional) Enable the web services logs.

Create an ACO for the Web Services

You can manage the web services through an ACO. To use the web services, you must enable the enableauth parameter or the enableaz parameter or both.

Follow these steps:

  1. Create an ACO that is based on the AuthAzServiceDefaultSettings template in Administrative UI.

  2. Configure the following parameters:

    • AgentName

      Defines the names of the web agent that protects a resource. You can define one or more web agents where each web agent protects an application. Enter a multi-value pair in the following format:

      agent_name

      ,

      appID

      • agent_name

        Defines the name of the web agent that protects a resource.

      • appID

        Defines the reference name of the web agent that was specified in agent_name or of the application that is protected by the web agent.

        SiteMinder

        uses this value in the web services requests, thus protecting the agent name from the users.

    • enableauth

      Specifies the status of the authentication web service. If you want to use the authentication web service, set the value to yes.

    • enableaz

      Specifies the status of the authorization web service. If you want to use the authorization web service, set the value to yes.

    • RequireAgentEnforcement

      Specifies whether the web services must be protected by a

      SiteMinder

      agent. Set this value to yes and protect the web services by a

      SiteMinder

      Agent. If you set the value to yes and the web services are not protected, the requests to web services fail.

  3. Save the changes.

Enable the Web Services

Use the ACO that you created in the previous procedure to enable the web services through Administrative UI.

If the values of enableauth and enableaz are set to no, the web services do not function even though you enable the support through

Access Gateway

Administrative UI.

Follow these steps:

  1. Navigate to Web Services, Auth and Az Web Services.

  2. Enable theAuth and Az Web Services option.

  3. Type the unique host name of the web services virtual host in Host Name.

    Note

    : Ensure that you specify a correct FQDN.

    Access Gateway

    creates avirtual host and enables the web services.
  4. Type the name of the ACO that is created for the web services in Agent Configuration Object.

  5. Click Save.

    The web services are enabled.

Mitigate DTD External Entity Injection in the Web Services

Configure the web.xml file to mitigate the DTD external entity injection in the web services.

Follow these steps

:
  1. Stop Access Gateway.

  2. Navigate to

    AG_installation_path

    \Tomcat\webapps\CA_AuthAZ\WEB-INF and open the web.xml file.
  3. Verify whether the file contains the

    customjaxbparsingrequired

    and

    xmlvalidationrequired

    parameters, and ensure that

    customjaxbparsingrequired

    isset to

    true

    .If the parameters are not present in the file, add the following lines of code after the

    <web-app>

    element:

    <context-param> <param-name>customjaxbparsingrequired</param-name> <param-value>true</param-value></context-param><context-param> <param-name>xmlvalidationrequired</param-name> <param-value>false</param-value></context-param>

  4. Save the change.

  5. Start Access Gateway.

Protect the Web Services

We recommend that you protect the web services. Protecting the web services lets

SiteMinder

authenticate and authorize the web services client before a user request is processed. When you protect the web services in your production environment,

Access Gateway

includes the SMSESSION cookie into the user request. If the RequireAgentEnforcement ACO parameter is enabled, theuser request is verified for the SMSESSION cookie before processing the user request.

You can protect the root URL of the web services using the Basic authentication scheme or X.509 Client Certificate authentication scheme or JWT authentication scheme. We recommend that you use the X.509 Client Certificate authentication scheme.

To protect the authentication and authorization web service using a basic authentication scheme, perform the following steps:

  1. Create a basic authentcation scheme for the web service.

  2. Protect the authentication and authorization web service root URL with the basic authentication scheme created in Step 1.

For more information about using the basic authentication, see How to protect Auth/Az Web services with Basic Authentication.

To access the protected web service client request, perform the following steps:

  1. Combine the username and password into the username:password string format.

  2. Encode the string using Base64.

  3. Send the encoded string in the header in the following format:

    Authorization: Basic

    encoded_string

To protect the authentication and authorization web service using an X.509 Client Certificate authentication scheme, perform the following steps:

  1. Create an X.509 Client Cert authentication scheme for the web service with the following Server Name:

    Server Name

    Defines the FQDN host name of the web service virtual host that you created in

    Access Gateway

    .

  2. Protect the web service root URL with authentication scheme created in Step 1.

  3. Create a certificate mapping for the root certificate in

    SiteMinder

    Administrative UI.

To access the protected web service client request, you must sendthe X.509 client certificate along with the web service request. If a user accesses with a valid client certificate, the request is validated and the web service is accessed.

For more information about using theX.509 Certificate authentication scheme, see Access Gateway:Auth/AZ Web Service with Certificate Authentication and Access Gateway:X.509 Cert Authentication.

To protect the authentication and authorization web service using JWT authentication scheme, perform the following steps:

  1. Create a JWT authentication scheme for the web service.

  2. Protect the web service root URL with authentication scheme created in Step 1.

The authentication and authorization Web Service accepts JWT and generates an SMSESSION. When a client sends a valid JWT to authentication and authorization web service, Policy Server authenticates the user and web service generates an SMSESSION. If there is an invalid JWT, the authentication and authorization service does not generate an SMSESSION.

For more information about using the JWT authentication scheme, see JSON Web Token (JWT) Authentication Scheme (Release 12.8.03 and later).

Enable the Web Services Logs

Configure

Access Gateway

to enable the web services logging.

Note

:If you customized the authaz-log4j.xml file in your current version, ensure that you take a back up of the file before you upgrade

Access Gateway

and customize it after the upgrade.

Follow these steps

:
  1. Navigate to

    AG_installation_path

    \CA\secure-proxy\proxy-engine\conf\webservicesagent

    .
  2. Open the authaz-log4j.xml file.

  3. Uncomment the following appender in the

    Appenders

    section:

    <RollingFile name="AuthAZ_ROLLING" fileName="logs/authazws.log" filePattern="logs/authazws.log.%d{MM-dd-yy-HH-mm-ss}.%i"> <PatternLayout> <Pattern>%d{yyyy-MMM-dd HH:mm:ss,SSS} - %p - %c - %m%n</Pattern> </PatternLayout> <Policies> <SizeBasedTriggeringPolicy size="10 MB" /> <OnStartupTriggeringPolicy/> </Policies> <DefaultRolloverStrategy max="10"/> </RollingFile>

  4. Uncomment the following appender of the

    com.ca.soa.services.authaz.webservice

    logger in the

    Loggers

    section:

    <AppenderRef ref="AuthAZ_ROLLING" />

  5. Uncomment the following appender of the

    com.ca.soa.services.authaz.webservice.rest

    logger in the

    Loggers

    section:

    <AppenderRef ref="AuthAZ_ROLLING" />

  6. Set the log level to

    DEBUG

    in all the instances of the file.
  7. Save the changes.

  8. Restart the web services.

  9. Verify that authazws.log is generated at

    AG_installation_path

    \CA

    \CA\secure-proxy\proxy-engine\logs

    .

Create the Client Program

Once the web services are configured by the SiteMinder administrator, the application programmer has to create the client program. The function of the client program is to issue authentication and authorization requests to the web service on behalf of another application. The client program requires code for a client stub. The stub manages, sends, and receives messages to communicate with the web service. The web service support a WSDL file (for the SOAP protocol) and a WADL file (for the REST architecture). You can access the WSDL or WADL file using a web browser, and then save it as an XML file.

Follow these steps:

  1. Write the business logic for your application, which gathers the required credentials.

  2. Create the client stub. Optionally, you can use the WSDL or WADL file with a third-party tool to generate the client stub.

    • To load the WSDL, use the following URL:

      http://

      hostname

      :

      port

      /authazws/auth?wsdl

    • To load the WADL, use the following URL:

      http://

      hostname

      :

      port

      /authazws/AuthRestService/application.wadl

    To retrieve the metadata from these locations, be sure to set the DefaultAgentName parameter in the ACO to one of your agents.

  3. Import the client stub and instantiate the stub object to invoke the web service.

The sections that follow list simplified sample SOAP and REST messages for reference.

Authentication SOAP Interface

These simplified samples show how authentication works using the SOAP protocol. Most authentication schemes can be supported by an IdentityContext consisting of just three fields: username, password, and binaryCreds. The value of binaryCreds contains either certificate data or JWT depending on the authentication scheme that is used.Other authentication schemes that require more fields are supported by additional operations whose inputs are tailored to the credential type.

The following example is an authentication web service normal user login request:

<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:aut="http://www.ca.com/siteminder/authaz/2010/04/15/authaz.xsd"> <s:Header/> <s:Body> <aut:login> <identityContext> <userName>user1</userName> <password>user1</password> <binaryCreds></binaryCreds> </identityContext> <appId>app1</appId> <resource>/*</resource> <action>GET</action> <sessionToken></sessionToken> </aut:login> </s:Body> </s:Envelope>

The blogin operation (Boolean Login) is similar to the login operation. However, blogin does not return a SMSESSION value in the response, as shown in the following example:

<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:aut="http://www.ca.com/siteminder/authaz/2010/04/15/authaz.xsd"> <s:Header/> <s:Body> <aut:blogin> <identityContext> <binaryCreds> </binaryCreds> <password>user1</password> <userName>user1</userName> </identityContext> <appId>app1</appId> <action>GET</action> <resource>/*</resource> </aut:blogin> </s:Body> </s:Envelope>

The following example represents a successful login response:

<s:Header/> <s:Body> <aut:loginResponse xmlns:aut="http://www.ca.com/siteminder/authaz/2010/04/15/authaz.xsd"> <return> <message>Authentication Successful</message> <resultCode>LOGIN_SUCCESS</resultCode> <sessionToken>session</sessionToken> <authenticationResponses> <response/> <response/> </authenticationResponses> </return> </aut:loginResponse> </s:Body></s:Envelope>

The following example represents a failed login attempt:

<S:Envelope xmlns:S="http://www.w3.org/2003/05/soap-envelope"> <S:Body> <ns2:loginResponse xmlns:ns2="http://www.ca.com/siteminder/authaz/2010/04/15/authaz.xsd"> <return> <message>Authentication Failed</message> <resultCode>LOGIN_FAILED</resultCode> <authenticationResponses> <response> </response> </authenticationResponses> </return> </ns2:loginResponse> </S:Body></S:Envelope>

The following example represents an authentication web service user logout request:

Even though a user has successfully logged out, the agent can still use the SessionToken to authorize, because it is considered to be a valid user credential.

<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:aut="http://www.ca.com/siteminder/authaz/2010/04/15/authaz.xsd"> <s:Header/> <s:Body> <aut:logout> <sessionToken>session</sessionToken> </aut:logout> </s:Body></s:Envelope>

The following example represents a successful authentication web service logout response:

<S:Envelope xmlns:S="http://www.w3.org/2003/05/soap-envelope"> <S:Body> <ns2:logoutResponse xmlns:ns2="http://www.ca.com/siteminder/authaz/2010/04/15/authaz.xsd"> <return> <message>Logout Successful</message> <resultCode>LOGOUT_SUCCESS</resultCode> </return> </ns2:logoutResponse> </S:Body></S:Envelope>

Authentication REST Interface

REST means REpresentational State Transfer. In REST, service requests transform the state of objects accessible by URIs. HTTP drives state change using actions such as create, read, update, and delete.

The URI mapping for authentication and authorization consists of the appId and resourcePath. The resource state is the collections of authenticated or authorized users associated with the Resource. The service names for authentication are login, blogin, and logout.

REST interface supports both JSON and XML request and response formats.Toget a response in JSON format for the REST based interfaces, add Accept Header with

application/json

as the value while sending the request.

A URI in this format, http://hostname:port/authazws/AuthRestService/login/

appID

/

Resource

, posts the following request:

Release 12.8 and 12.8.01

:

<loginRequest> <username>user1</username> <password>user1</password> <action>GET</action> </loginRequest>

Release 12.8.02 and later

:

<loginRequest> <userName>user1</userName> <password>user1</password> <action>GET</action> </loginRequest>

JSON request format:

Release 12.8 and 12.8.01

:

{ "binaryCreds": "", "password": "user1", "username": "user1", "action": "POST"}

Release 12.8.02 and later

:

{"binaryCreds": "","password": "user1","userName": "user1","action": "POST"}

The login responses:

HTTP return code 200

<loginResponse><message>Authentication successful</message><resultCode>LOGIN_SUCCESS</resultCode><sessionToken>session</sessionToken><authenticationResponses> <response> <name>SM_SESSIONDRIFT</name> <value>0</value> </response></authenticationResponses></loginResponse>

JSON Response format:

{ "authenticationResponses":

{"response": [

{"name": "SM_USER","value": "uid=user1,ou=People,o=security.com"},{"name": "SM_SESSIONDRIFT","value": "0"}

]}, "message": "Authentication Successful", "resultCode": "LOGIN_SUCCESS", "sessionToken": "session"}

HTTP return code 400

<loginResponse>

<message>Bad Request</message> <resultCode>LOGIN_ERROR</resultCode></loginResponse>

JSON Response Format

{ "message": "Bad Request", "resultCode": "LOGIN_ERROR"}

HTTP return code 200

<loginResponse><message>Authentication Failed</message><resultCode>LOGIN_FAILED</resultCode><authenticationResponses> <response><name>SM_AUTHREASON</name> <value>0</value> </response> </authenticationResponses></loginResponse>

JSON Response Format

{ "message": "Authentication Failed", "resultCode": "LOGIN_FAILED"}

HTTP return code 500

<loginResponse> <message>System</message> <resultCode>Server Error</resultCode></loginResponse>

JSON Response Format

{ "message": "System", "resultCode": "Server Error"}

The bLogin operation (Boolean Login) is similar to login. A URI in this form, http://host:port#/blogin/appId/resourcePath posts as shown in the login request. It returns yes or no in the response message.

A URI in this format, http://host:port#/authazws/AuthRestService/logout/, posts the following the logout request:

<logoutRequest><sessionToken>session</sessionToken></logoutRequest>

JSON logout request format:

{ "sessionToken": "session"}

The authentication web service logout responses:

<logoutResponse> <message>Logout Successful</message> <resultCode>LOGOUT_SUCCESS</resultCode></logoutResponse>

<logoutResponse> <message>Logout Failed</message> <resultCode>LOGOUT_FAILURE</resultCode></logoutResponse>

JSON logout response format:

{ "message": "Logout Successful", "resultCode": "LOGOUT_SUCCESS"}

{ "message": "Logout Failed", "resultCode": "LOGOUT_FAILURE"}

Authorization SOAP Service

The following XML approximates an authorization request to the web service:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:aut="http://ca.com/2010/04/15/authorization.xsd"> <soapenv:Header/> <soapenv:Body> <aut:authorize> <sessionToken>session</sessionToken> <appId></appId> <action>GET</action> <resource>/domainAdmin/a.jsp</resource> </aut:authorize> </soapenv:Body></soapenv:Envelope>

You can replace GET with POST in the action.

The following example represents an authorization web service AUTHORIZED response:

<S:Envelope xmlns:S="http://www.w3.org/2003/05/soap-envelope"> <S:Body> <ns2:authorizeResponse xmlns:ns2="http://www.ca.com/siteminder/authaz/2010/04/15/authaz.xsd"> <return> <message>Authorization successful</message> <resultCode>AUTHORIZED</resultCode> <sessionToken>sWNuJjptq1XhS</sessionToken> <authorizationResponses> <response> </response> </authorizationResponses> </return> </ns2:authorizeResponse> </S:Body></S:Envelope>

The following example represents an authorization web service UN AUTHORIZED response:

<S:Envelope xmlns:S="http://www.w3.org/2003/05/soap-envelope"> <S:Body> <ns2:authorizeResponse xmlns:ns2="http://www.ca.com/siteminder/authaz/2010/04/15/authaz.xsd"> <return> <message>Authorization Failed</message> <resultCode>NOTAUTHORIZED</resultCode> <authorizationResponses/> </return> </ns2:authorizeResponse> </S:Body></S:Envelope>

For an authorization web service request with a valid session token, the NOTAUTHORIZED authorization response has the following constraints:

  1. You can configure the response with only the following attributes in the Administrative UI:

    • SM_ONREJECTTEXT

    • SMREDIRECTURL or SM_REDIRECTURL

    • SMERROR

  2. The response does not contain a session token.

Authorization REST Interface

<authorizationRequest><action>POST</action><sessionToken>affl;;alkf;l;fd</sessionToken></authorizationRequest>

JSON authorization request format:

{ "action": "POST","sessionToken": "session"}

HTTP return Code 200:

<authorizationResult> <message>Authorization successful</message> <resultCode>AUTHORIZED</resultCode> <sessionToken>session</sessionToken> <authorizationResponses> <response> <name>SM_USERDN</name> <value>uid=user3,ou=People,o=security.com</value> </response> </authorizationResponses></authorizationResult>

JSON authorization response format:

{ "authorizationResponses": {"response": [

{"name": "SM_USER","value": "uid=user1,ou=People,o=security.com"}

]}, "message": "Authorization successful", "resultCode": "AUTHORIZED", "sessionToken": "session"}
