Urgent: JAAS Login Module Deployment Problem

Question

Hi,
I have developed a JAAS Login module for the portal (EP6 SP9 sneak preview) and i am getting the following error:
GroupAssignmentLoginModuleLibrary does not exist in LoadContextWrapper.modifyName.
com.sap.engine.services.security.exceptions.BaseSecurityException: Can not load a login Module
The next line is a ClassNotFoundException for the Login Module and the class found in negative cache.
Please let me know if you know the solution to this problem.
It is an urgent issue and a solution will be suitably rewarded.
Regards,
Vibhu

Hi Diego,
Scenario 1: SAP EP to SAP Backend Integration
      In this scenario the most commonly used strategy
      is SAP logon tickets. As far as I know this is the
      best and simple way to implement SSO.
Scenario 2: SAP EP to Non SAP systems.
      In this scenario various mechanisms can be used.
      It depends on the application you are integrating
      with. SAP does deliver SSO soultions with Lotus
      Notes and Outlook etc. If supported probably it is
      simple to use the SAP solution [Reliability and
      Support].
Scenario 3: Enterprise Uses third party authetication
      Software.
      For the authntication if the company chooses to use
      some third party product like SiteMinder etc, then
      you can simply use this solution for SAP EP authe-
      tication, and also all your other enterprise
      applications based on the product support. But SAP
      EP to other SAP systems be best integrated with SAP
      logon tickets.
Scenario 4: SSO using homegrown authetication or some
      third party JAAS module.
      If you have significant applications that are home
      grown that uses some custom authentication mecha-
      nism (Example: Authentication based on ID and
      Password stored in company database ) you can write
      a JAAS module extention to authenticate using that
      database. In other words JAAS is flexible and
      for using external authentication mechanisms.
There are several mechanisms available that all depends
on your internal applications/security mechanism/integration etc.
Here is the link to one of the good articles on SDN about the SAP supported SSO mechanisms.

Hope this information is useful.
