Hi all, I'm currently trying to iron out a procedure how to setup NFSv4 with Winbind. We use a setup with: Ubuntu Lucid (10.04) Windows A 2003 Winbind I have successfully configured NFSv4 with MIT KRB5 KDC but with AD there is still some problems... By default rpc.gssd tries to login with a principal name like host/client01.test.net. The AD KDC rejects this and tells me that it does not exist. It seems to me that AD makes a difference between userPrincipalName and servicePrincipalName when an AS-REQ is done. The userPrincipalName on my client is CLIENT01\$ and I can kinit with this name. rpc.gssd have an "-n" option that allows me to do a kinit before I start this daemon: # kinit -Rk CLIENT01\$ # rpc.gssd -n I can mount (krb5i) with this setup and I can get access to the share *** But only if I use the same Kerberos machine credentials *** I have tried to get any useful information with Wireshark and verbose logging, but all seems to be successful (KRB and NFS packages); The user gets an access denied message. I have two theories about this: 1. Rpc.gssd with the -n option behaves different and I need to make it use the correct keytab by modifying the code (maybe with a new option like "-P CLIENT\$@TEST.NET"). 2. Rpc.svcgssd needs to be extended in the same way with an -n option Does this seem likely?
