I'm trying to switch a working kerberos server from targeted/enforcing
to mls/enforcing. The krb5kdc daemon start fine, but kadmin does not.
There is a single avc in the audit log:
type=AVC msg=audit(1219421464.372:719): avc: denied { getattr } for pid=2436 comm="kadmind" path="/var/tmp/kadmin_0" dev=dm-5 ino=82064 scontext=system_u:system_r:kadmind_t:s0-s15:c0.c1023 tcontext=system_u:object_r:unlabeled_t:s15:c0.c1023 tclass=file
I ran this through audit2allow and loaded the module, with no luck. I
ran 'semodule -DB' to see what else was being hit and not audited, and
get quite a few more:

running this through audit2allow and loading the module doesn't help
either... What can I try next?
