J2EE Agent Use Case 2: Accessing a Protected Resource in a Non-Primary Domain First (Technical Note: Sun Java System Access Manager Cross-Domain Single Sign-On)

Technical Note: Sun Java System Access Manager Cross-Domain Single Sign-On

J2EE Agent Use Case 2: Accessing a Protected Resource in a Non-Primary Domain First

In this use case, an unauthenticated user first accesses a protected resource in the non-primary domain (.sun.com). He then accesses a protected resource in the primary domain (.iplanet.com).

An unauthenticated user attempts to access http://comal-b.central.sun.com:80/app1/test1.html. The policy agent intercepts the request and receives no SSO token. Because the SSO is enabled, the agent responds with a redirection to the Access Manager CDC servlet URL https://am-pool0.red.iplanet.com:8443/amserver/cdcservlet.

The browser follows the redirection to access the CDC servlet without any SSO token. The CDC servlet responds with a login page.

<.... login page content omitted by author ...>

The user types in his credential on the login page and clicks Submit. A login form is posted to Access Manager. If the user authenticates successfully, the Access Manager responds by setting an SSO token (iPlanetDirectoryPro) in the domain .iplanet.com. The response also redirects the browser back to the CDC servlet https://am-pool0.red.iplanet.com:8443/amserver/cdcservlet.

The browser follows the redirection to access the CDC servlet again. This time the SSO token iPlanetDirectoryPro is sent in the HTTP request because the server DNS domain matches the cookie domain. The CDC servlet validates the SSO token and responds with an HTML page. The page contains a HTML FORM which will be automatically posted to CDSSO Redirect URL on the agent (http://comal-b.central.sun.com:80/agentapp/sunwCDSSORedirectURI). The form's hidden field LARES is an encoded Liberty-like AuthnResponse that contains the existing SSO Token in the domain .iplanet.com.

The browser automatically posts the form with LARES to http://comal-b.central.sun.com:80/agentapp/sunwCDSSORedirectURI without the user interaction. The agent responds by setting a new SSO token iPlanetDirectoryPro with an empty cookie domain. A cookie with an empty DNS domain will have the server FQDN as the domain. Also note the cookie value is exactly the same as the one set in Step 3 response by Access Manager. The only difference is the cookie domain. The HTTP response also redirects the browser to the original requested resource http://comal-b.central.sun.com:80/app1/test1.html.

The user now attempts to access http://am-v210-01.red.iplanet.com:7001/app1/test1.html. A SSO token is sent with the HTTP request. The browser currently has two SSO Tokens, one for each domain. The token sent was obtained in Step 3. The agent intercepts the request and receives the SSO token. The agent validates the token and permits the server to serve the content of the protected page.
