query kerberos with C?

[Rainer Sigl]

Hi all,
I'm rel. new with kerberos beside using it with afs.
My question: are there easy c-interfaces to ask a kerberos server for 
username, password or setting up new users on keberos?
In my special case I have user database on postgresql. the stored 
usernames, passwords which are till now used for authorizing by our 
email server. Now I wish to have the same passwords on my postgresql 
database and our afs server. This could work for example by writing 
c-functions on postgresql that fetches the corresponding password for a 
username and can create new user entries on kerberos.
Is there any way to this?

Many thanks
Rainer Sigl
