teething pains

[N. Leenders]

Hi,
I'm new to this list and to setting up kerberos and am running into some
problems.

When running kadmin.local, while cleaning up some of the test principals
I'd set up, I also removed "K/M at NIC.UALBERTA.CA", not realizing that the
system had put it there.  Since then, I haven't been able to run
kadmin.local:

[root at lyon root]# kadmin.local
Authenticating as principal root/admin at NIC.UALBERTA.CA with password.
kadmin.local: Cannot find master key record in database while initializing
kadmin.local interface

So I tried destroying the database so I could start over:
[root at lyon root]# kdb5_util destroy
kdb5_util: No such entry in the database while retrieving master entry

And it didn't work to try creating a new one either:
[root at lyon root]# kdb5_util create -r NIC.UALBERTA.CA -s
create: The database '/var/kerberos/krb5kdc/principal' appears to already
exist

What else can I try?
Thx, Nadine
