Why does Domino prompt for User Name and Password when using SSO?

I am trying to configure SSO between WebSphere Application Server 5.0.2 (AIX 5.2) and Domino 6.5.1 (AIX 5.2).

However, when I log in as a user on the WebSphere server, and try to connect to the Domino server using SSO, I am prompted again (by Domino) for my username/password. If I enter this, I am able to log in ok but this shows that SSO is not working!

The following was completed successfully:

  1. Importing of the LTPA key to Domino

  2. Creation of the SSO document in Domino PAB

  3. Selection of “Multiple Servers” and “LTPA Token” in PAB

  4. On restarting Domino server, I get messages that appear to indicate succesful starting of SSO:

LDAP Server: Starting…

LDAP Server: Serving directory names.nsf in the acme.local Internet domain

LDAP Schema: Started loading…

LDAP Schema: Finished loading

LDAP Server: Started

I did manage to get this working on our development environment (also Domino 6.5.1 but this time Windows NT rather than AIX), with an almost identical configuration - could there be a platform issue here?

I’d really appreciate any help or suggestions.

Remember that the LTPA key from Websphere is different than the one from Domino.

The steps you gave are correct, but you need to do a key export out of Websphere and an import into the Domino key.

Have a look on the IBM web site for a Red Paper on the subject. It will guide you step by step.

Thanks for the advice…I’ve now located the problem…the WebSphere and Domino LTPA cookies were different…restarting the WebSphere server fixed the problem and SSO works now.Dan
