[OpenAFS] kerberos and remote authentication

[lamont@scriptkiddie.org]

I'm trying to setup remote client/server kerberos authentication using the 
AFS krb4 kaserver.  I'd prefer to not use kerberized ssh since I have my 
doubts about being able to make the API I want to implement meet my goals 
for security, config management and stability based on previous 
experiences with APIs over ssh.  And I'd like to use the built-in kaserver 
for now because it allows me to punt the issue of deciding on how to build 
an enterprise-wide krb5 infrastructure.

So far I've found the klog.krb and pagsh.krb commands to get a ticket.  I 
want to be able to use that ticket over a socket and authenticate to a 
remote server.  I'm a complete kerberos n00b and haven't been able to find 
any good example code to play with despite a couple of days of googling. 
I've found the Authen::Krb4 perl module, but the documentation is about as 
sparse as it could possibly be.  Is there any good example code out there 
of how to do this written in either C or Perl?  Is there any bad example 
code out there?  I'd even take diffs in C for kerberizing an example 
application...  Book recommendations would also be appreciated...
