Hi, We are upgrading to Kerberos for Windows 3.1 and some clients have problems with the Network Identity Manager, which crashed after obtaining a ticket. The Network identity manager works fine (i.e. does not crash) until you get a ticket using New credentials. A second after obtaining the credentials, the Network Identity Manager crashes, every single time. We are running Windows XP SP2 and have AFS client 1.5.13a and 1.5.14. Please see the attached crash dump file and log file (the crash dump is from a system running AFS 1.5.14. The problem seems to be with AFSAUTHENT.DLL. Regards Andreas Stenhall
