A DESCRIPTION OF THE PROBLEM :
We are using Krb5LoginModule in one of the POC.
I have provided useDefaultCache=true and renewTGT=true.

The code throws an exception when the ticket is expired although I have mentioned renewTGT=true. I have set up allowtgtsessionkey value to 1 in registry. The KDC (ActiveDirectory) settings are default. Ticket lifetime = 10 hours and renewal request threshold = 7 days.

Can you please help me in figuring out what could be wrong?
