Unable to connect to CLM with TAM/WebSeal using Eclipse

A user has CLM 4.0.5 set up with Tivoli Access Manager / WebSeal and is unable to connect to the server using Eclipse Client. When trying to configure a connection in Eclipse, got the following error:

CRJAZ6025E Cannot log into the server,'https://server1.example.com/server2.example_s9443/ccm/',
because the network stated that the server is invalid or unknown <https://server1.example.com/server2_example_s9443/ccm/%27%2c because the network stated that the server is invalid or unknown> . For more details, open the help system and search for CRJAZ6025E.


Eclipse's .log show the following error:

!ENTRY com.ibm.team.repository.client 1 800 2014-11-17 16:59:18.948

In the WebUI, users can login successfully.

TAM/WebSeal is enabled in this environment. It is not configured for SSO.


QUESTIONS:
1. With this setup with TAM/WebSeal, should a user be able to connect to the server using Eclipse client?
2. What would be a valid URL syntax to use? Is the URL in the error message supported in Eclipse? (it works fine in a browser)
3. How can I address the above error?
