On a customer site I had to make sure that users are able to authenticate via HCL Sametime Embedded Clients, inside of HCL Notes 9.0.1 Basic Client, using Domino SSO (LTPA).
After installing the HCL Sametime 11 Community Server, and applying the standard configuration, the login via Domino SSO for Sametime embedded clients inside of HCL Notes standard or eclipse clients worked without any issues. But we had to make some configuration changes in the “sametime.ini” file to make the same work for ST Embedded clients inside the HCL Notes basic clients.
We had to change the “VP_SECURITY_LEVEL” parameter value from the default “7000” to “0”. Furthermore, we added the value “1216” to the “VPS_PREFERRED_LOGIN_TYPES” parameter. If the “VPS_ALLOWED_LOGIN_TYPES” parameter is used in your environment, then you will have to add “1216” value to this parameter as well.
After saving the “sametime.ini” file and restarting the Sametime Community server, the Sametime embedded clients, inside the Notes basic clients, should be able to login via Domino SSO Mechanism.
