Storing TGT in cache

[Richard Gundersen]

Hi

In case my previous question didn't sound clear, I've done some digging and 
found that Wedgetail have an Java API for Kerberos. The JavaDoc describes a 
class called FileCredentialStore which has a method put(Credential) which 
can be used to store a ticket in a file cache.

This is exactly the functionality I want. Ideally I'd like to find out how 
to do this myself (legally!). If I were to write such a mechanism myself are 
there specific rules I need to follow in terms of how I persist the ticket 
in the cache so that it complies with Kerberos? Or would it be valid to come 
up with some proprietary method of persistence? E.g. if I am using Suns 
Krb5LoginModule to read from the cache, the format I save it in, encryption 
used etc, must be well defined.

Any suggestions very gratefully received!

Regards
