Accessing AD resources from Linux clients work perfectly. Accessing resources in the MIT Kerberos realm from Windows fails more often than not. Lots of packet sniffing shows fragmented UDP packets which the unix server isn't able to reassemble. So, in accordance with http://support.microsoft.com/kb/244474 we've set HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa\ Kerberos\Parameters\MaxPacketSize to 1 on the XP clients. Still no go, they never try TCP (again sniffing both on the XP client and the unix kerberos server) but go straight for TCP. TCP is working on the unix kerberos server, the linux clients are happily using it. Have anyone seen MaxPacketSize fail to have effect before? Any ideas on how to trace this further? -BT -- Bjørn Tore Sund Phone: 555-84894 Email: bjorn.s...@it.uib.no IT department VIP: 81724 Support: http://bs.uib.no Univ. of Bergen When in fear and when in doubt, run in circles, scream and shout. ________________________________________________ Kerberos mailing list Kerberos@mit.edu https://mailman.mit.edu/mailman/listinfo/kerberos **** This message and any attachment are confidential, intended solely for the use of the individual or entity to whom it is addressed and may be protected by professional secrecy or intellectual property rights.
