Since the Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability
was disclosed by Microsoft on Nov 8 2022 and per RFC8429 it is assumed that
rc4-hmac is weak, Vulnerable Samba Active Directory DCs will issue rc4-hmac
encrypted tickets despite the target server supporting better encryption
(eg aes256-cts-hmac-sha1-96).
