krb5kdc: Cannot find master key record in database - while fetching master keys list for realm

[Tom Parker]

Hi

I have a Kerberos server that has been running for months with out any
problems. 

Today when I went to log into my kdc machine I had the following error
in my logs:

May 09 10:47:52 svgauth1 krb5kdc[2451](Error): TGS_REQ: UNKNOWN SERVER:
server='krbtgt/VC.LS.CBN at LS.CBN'
May 09 10:47:52 svgauth1 krb5kdc[2451](info): TGS_REQ (4 etypes {18 17
16 23}) 172.20.133.141: PROCESS_TGS: authtime 0,  <unknown client> for
<unknown server>, Server not found in Kerberos database

I am using the ldap backend and I checked in LDAP and everything looked
ok so I attempted to restart my kdc.

My kdc failed to restart with: krb5kdc: Cannot find master key record in
database - while fetching master keys list for realm VC.LS.CBN

I have the K/M at VC.LS.CBN principal in the ldap directory and it looks ok.

Any ideas as to where my problem may be?  Can this entry be corrupted
some how and not load?

I am running the following versions:

krb5-1.8.3-45.1
krb5-plugin-kdb-ldap-1.8.3-45.1
krb5-client-1.8.3-45.1
krb5-32bit-1.8.3-45.1
pam-krb5-4.4-1
krb5-server-1.8.3-45.1

Thanks for any insight.
