javax.security.auth.login.LoginException: Could not obtain TGT

Hi,

Not sure if this is the correct place to post this question, but we are getting this error when trying to authenticate a user. This seems to happen only sporadically.

May I know what are the possible causes of this error? Is it due to load / concurrency ?

We are using Weblogic 8.1.


Thanks so much for your help!


cheers
