The gadget that Cisco provides for eGain's OEM integration (EIM/WIM) doesn't provide single sign-on of any kind. Neither does the eGain Solutions Plus gadget that eGain provides.
I added simple single sign-on using the Finesse javascript API to retrieve the agent login credentials, but this only works for agent ID logins, and not for username logins. The issue is that the Finesse javascript API (as of version 10.5) will only return the agent ID, whether you logged in to Finesse using your agent ID or agent username. The Finesse REST API, however, will provide you with 'loginName', which will correctly return which one you used to log in with.
Here's the repository for the updated gadget:
