I've been seeing the following message in the browser: -
com.ibm.websphere.servlet.error.ServletErrorReport: CLFRQ0355E: It is not possible to retrieve the tab instance ID. An error occurred while getting the internal ID of the authenticated user from the session.
when I access the Homepage feature via a load balanced pair of HTTP servers.
I was also seeing the following exceptions in SystemOut.log: -

Whilst this Technote: -
is interesting, it's not totally relevant in my scenario.
Similarly, this section of the Information Centre: -
is of some use: -
CLFRQ0221E: Reference to directory services could not be retrieved. It was not possible to access Lotus Connections directory services while running an administration configuration task.
• Verify that Lotus Connections directory service is installed correctly.
• Check that the LDAP server for the configuration is available (if you choose to use one).
• Verify that the database for the directory service has been installed correctly.
CLFRQ0341E: Could not retrieve details for the user with login ID: {0} due to an exception. The exception occurred when retrieving the details via Profiles Directory Service Extension: {1} Information about a user could not be retrieved from the directory service.
• Verify that Lotus Connections directory service is configured correctly.
• Check that the LDAP server for the configuration is available (if you choose to use one).
• Verify that the Home page database has been installed correctly.
again it didn't really help.
I *think* I have cracked the problem; it's my old friend IPTables again, this time blocking connections from the HTTP servers to the Connections servers ( each feature is deployed as a clustered pair of application servers, deployed across two physical nodes ).
In my use case, when I attempt to authenticate from Homepage ( listening on 9082 ), the request is sent, via HTTP ( no SSL here ) to Profiles, which listens on port 9088.
I've semi-proved this by attempting to connect from the HTTP server, via the TELNET command, to the respective ports on my Connections nodes: -
telnet connections1.demo.uk.ibm.com 9082
telnet connections1.demo.uk.ibm.com 9088
etc. where 9082 is the "real" port for Homepage and 9088 is the "real" port for Profiles.
Both commands fail with: -
telnet: Unable to connect to remote host: No route to host
which is kinda familiar.
I'm waiting for the firewall guru to fix this but ....
