Hi, I am using the same source code for my SpnegoAuthenticator with an Oracle JVM on Windows and a HP VM on HP-UX. Something must be different/wrong with the JGSS Provider from IBM. What you could do is download my source [1], change the lifetime to GSSCredential.INDEFINITE_LIFETIME and see whether it fixes the problem. Michael [1] http://tomcatspnegoad.sourceforge.net/download.html Thanks Michael. It did solve the issue. Not sure, if it will be acceptable as a fix, due to constraints and stuff. Appreciate the effort :). This email and any files transmitted with it are confidential, proprietary and intended solely for the individual or entity to whom they are addressed.
