Thanks for the insights guys. Much appreciated.
I originally was approaching the problem by making use of the Authen::Krb5:Admin module which looked to have everything I was looking for.
However I had difficulty getting it to pass its "make test" on the sparc box and linux box I tried installing it on. Forcing an install yielded very limited functionality and I put it aside for the sake of expendiency. May take a crack at using the Dice::Kadm5 module to do the job when time allows.
Kerberos::MIT::Bulkloader sounds like a good tool for my initial loading of info, but it might not be suitable for doing small ongoing updates to the database. I'll be sure to check it out.
If anyone has had success with a particular perl module for doing the day-to-day care and feeding of an MIT kerberos KDC I'd love to hear about it.
