[OpenAFS] openAFS 1.4.4 - ticket contained unknown key version number

[Hamish]

I've got openAFS 1.4.4 (RPM x86_64 downloaded from openafs.org) running on 
RHES4 with kerberosV. Kerberos is installed & seems to be working OK. I can 
get a krb ticket with krb5 no problems. kadmin etc all work. I can create new 
principals (e.g. afs).

aklog works. It get a token and then tokens shows the token successfully 
generated... Working so far.

However when I try to execute a command that requires a token (e..g box 
restart, vos create etc), I get

bos: failed to restart instance fs (ticket contained unknown key version 
number)

I'm assumign thats ince aklog is in the RPM's that we're all OK for working 
with krb5. The fact that aklog works seems to confirm that.

Why the heck do I get an unknown key version when trying to do anything? I've 
googled till I'm blue in the face and have only found some really really old 
emails asking questions with no answers... The Wiki seems devoid of any info 
unless it's using kaserver when it comes to krb at all...


Anyone?

TIA
