BI Platform 4.1 with WinAD SSO: why BI Launchpad WinAD SSO sessions are indicated by "Logon Client without ID" in CMC?

Hi everybody,
in our BI 4.1 SP5 environment with activation of SSO with WinAD, when a user connects to BI LaunchPad portal using this type of authentication, in CMC \ Sessions the new session appears but in "Client Session" the system shows "without Client Logon ID".

With other applications like Explorer, no problems.

However, if Login is done without the use of SSO but, for example, with authentication WinAD only it correctly shows "BI LaunchPad" in "Client Session" field.

Does anyone know why and how to fix it?
Thank you
