Andreas:
Wireshark cannot show you the type of the session key since that key is
only visible to parties that are capable of decrypting the encrypted
portions of the response. It is the session key that must be des-cbc-*
and which is instead aes256-cts-hmac-sha1-96 in the 1.5.1 case.
klog.krb5 should be setting an explicit request for a des-cbc-crc
session key. That is a bug which must be fixed. It should be reported
to openafs-bugs@openafs.org.
Heimdal 1.5.1 should also be restricting the session key to one of the
encryption types that are known to the afs@IFH.DE principal. That is
also a bug and should be reported on the heimdal mailing list.
