I have a Kerberos delegation issue caused by the separation of IIS worker processes and the Tomcat server on Windows.
Specifically, the customer is running Tomcat through ISAPI on Windows with ISS using Integrated Windows Authentication (Kerberos). Authentication is working. The getRemoteUser method returns the user's expected identity. Delegation is working. An ASP can use the clients credentials to request another protected page on a second IIS server. Note, impersonation is not used in any way shape or form (nor would it work). I put together a Kerberos capable HTTP client and tried to invoke it through the IIS authenticated Servlet. This does not work. The JGSS routines cannot find the delegated ticket (TGT). I believe this is because Windows' credential caches are per logon session and IIS creates a new logon session for each authentication [1]. So, my question is, does Tomcat's ISAPI dll provide any mechainsm that might assist in getting delegated Kerberos credentials of clients authenticated using IIS's IWA? Has anyone encountered this issue before? Has anyone considered using GSSContext.export() and GSSManager.createContext() to export the Kerberos ticket and transfer it to the Tomcat worker? Or one might call LsaGetLogonSessionData [2] directly to make things as effecient as possible. This would be a nice feature as there are many pure MS SSO shops that don't like the idea of running Tomcat stand alone. Any comments are greatly appreciated. Mike [1] Actually I'm not entirely certain about the logon session partitioning in the IIS scenario but it suffices to say Tomcat cannot access that logon session. [2] The MIT kfw source is a good reference for directly querying the Windows credential cache. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
