The same i have now in the PowerShell:
VERBOSE: Attempting to connect using SSPI
VERBOSE: Reversely resolved 'vc' to 'vc.domain.intern'
VERBOSE: SSPI Kerberos: Acquired credentials for user 'domain\user'
VERBOSE: SSPI Kerberos: InitializeSecurityContext failed for target 'host/vc.domain.intern'. Error code: 0x80090303
VERBOSE: Connect using SSPI was unsuccessful
I found something with google, that the VCSA still needs to be a member of the AD, is that possible?
Perhaps i need to rejoin the VCSA to the AD but then still use the LDAPS for authentication and not the machine account?
