Re: [External] : Re: Windows Credential Guard with MSLSA

Hi Sam
Let me make it clear.

I am using Linux Server / MIT Libraries for server and Windows Client .  Microsoft Active Directory as KDC Host.

Scenario – 1
Credential cache stored with MSLSA – AllowTGTSessionKey<https://learn.microsoft.com/en-us/troubleshoot/windows-server/windows-security/kerberos-protocol-registry-kdc-configuration-keys> registry setting can be used to allow the Linux Kerberos MIT library  to retrieve credential cache from KDC Host for forwardable TGTs.

Scenario-2

Credential cache stored with Windows Credential Guard -  Do not know of any solution that allows Linux Kerberos MIT library to retrieve cache from the Windows Credential Guard as it uses signed certificates.  Looking for a solution.

Hope that helps.

Your question doesn't make sense.
MSLSA is not a Linux thing:
MS -> Microsoft
LSA -> local security authority

The LSA exists on Windows systems.
If you are not on a Windows system, you don't have one.

It may be that you want to be asking about credential guard and Linux.
But involvind MSLSA or LSA in the discussion only confuses everyone.
