Alexander Bokovoy 215bb9bd48 Do not fail checksums for RFC8009 types
While Active Directory does not support yet RFC 8009 encryption and
checksum types, it is possible to verify these checksums when running
with both MIT Kerberos and Heimdal Kerberos. This matters for FreeIPA
domain controller which uses them by default.
