Your database servers are {rock,ice,snow}.mcc.ac.uk. My guess is that the
tools are trying to figure out what Kerberos realm those are in, and get
tickets for that. Since there is no krb.realms entry, the realm is being
constructed by chopping off the first hostname component.
If I'm correct, the solution is to add the following line to
/etc/krb.realms:
mcc.ac.uk MCC.AC.GB
