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 BI4.1SP5environmentwithactivationofSSOwithWinAD, when a userconnects to BI LaunchPadportalusingthis type ofauthentication,in CMC\Sessionsthe new sessionappearsbutin "Client Session" the system shows "without ClientLogonID".

With other applications like Explorer, no problems.

However, ifLogin is done withoutthe useofSSObut, for example, withauthenticationWinAD only it correctlyshows"BILaunchPad"in "ClientSession" field.

Does anyone knowwhy and how to fix it?
Thank you
