What is the difference between "MEMORY:name" and "API:name"? I thought that 
only FILE:name cache preserves the ticket beyond the login process so they 
are available to the user later during the login session.

this "custom network provider" is not a customization of the one distributed
with openafs. It has been written here to allow our users to get kerberos 
tickets
at login time. It is a "kerberos integrated login". We are also using afs
integrated login to get afs tokens at login time.

As I mentioned above - I am using the OpenAFS.org integrated logon network 
provider.

I have installed the debug version of openafs 1.3.76, attached a debugger 
to afscreds.exe when it crashed. Now, forgive me my ignorance, but what 
exactly do I need to save (and later send to afs-bugs) from the debugging 
session?

This will be greatly appreciated.
