(RFC 4120 is actually silent on which is correct; RFC 4757 specifies the TGS session key.) To sidestep this interop issue, don't use keyed checksum types with RC4 keys without explicit configuration in krb5.conf. Using keyed checksum types with AES is fine since, experimentally, AD 2008 accepts checksums keyed with the TGS session key. https://github.com/krb5/krb5/commit/05c7822d0e5118df745685ab2f9b20fe07dcfb6c Commit By: ghudson Revision: 22356 Changed Files: U trunk/src/lib/krb5/krb/send_tgs.c
