[OpenAFS] DES session key after removal of KeyFile

[Staffan Hämälä]

For some reason, we're still getting a DES session key after removing 
the KeyFile on all OpenAFS-servers, and touching CellServDB, according 
to these instructions:
https://www.openafs.org/pages/security/install-rxkad-k5-1.6.txt

Old clients still work even though there is no DES in rxkad.keytab.

klist -v shows:
...
Server: krbtgt/LTU.SE@LTU.SE
...
Ticket etype: arcfour-hmac-md5, kvno 1
Session key: aes256-cts-hmac-sha1-96

Server: afs/ltu.se@LTU.SE
...
Ticket etype: aes256-cts-hmac-sha1-96, kvno 3
Session key: des-cbc-crc

What can be the cause of this?
