[OpenAFS] Kerberos 1.10.1 and OpenAFS
Wed, 04 Apr 2012 10:23:03 -0400
This is an OpenPGP/MIME signed message (RFC 2440 and 3156)
Content-Type: text/plain; charset=UTF-8
The 1.10 Kerberos distribution does not support weak encryption types
such as DES out of the box. If you do not explicitly enable support for
weak encryption types it won't matter what keys you have on service
principals or what other configuration is specified, weak encryption
keys simply will not be used. This is an incremental step towards the
removal of weak encryption types such as DES from the Kerberos ecosystem.=
The AFS service principal must have a working DES key. If it doesn't,
you cannot obtain service tickets for AFS that are usable.
