MS-KILE's PA-PAC-REQUEST sequence allows the Kerberos client to request
a TGT without a PAC. At the moment, there is no way to configure the MIT
KDC to reject such request.
This commit enforces the presence of the PAC when processing TGTs
provided by TGS-REQ. It ensures the server principal of the TGT is the
same as the one in PAC_CLIENT_INFO (i.e. enforces client principal
canonicalization) with integrity check.
Only one exception is applied: this check is skipped for local TGTs on
domain where the MS-PAC generator is not initialized (i.e. domains where
SID generation was not executed yet).
