I had successfully integrated Samba 3.0.20b on a test linux Fedora Core4 workstation with my Windows 2003 active directory server.
All permission are working fine through active directory ACL.

Problem now is; I am working on a production Redhat ES3 server.
It is using Samba 3.0.14.
Somehow using the same procedures and steps for Fedora, I could not get it to work with the same Win2k3 server.

This are the steps that I did:
edit /etc/samba/smb.conf - OK
edit /etc/nsswitch.conf - OK
edit /etc/krb5.conf - OK

kinit administrator@DOMAIN.COM - OK
net ADS join - OK

wbinfo -u / -g - FAILED
Error looking up domain users/groups

wbinfo -t - FAILED
checking the trust secret via RPC calls failed
error code was NT_STATUS_INTERNAL_ERROR

winbindd.log:
Error message was "SMB signature verification failed on incoming packet!"

I had looked everywhere for solution but no answer.
Anyone can help?

I have been working on something almost the same item. I was able to get the kinit command to work once I check the services and made sure that the nscd service was stopped and that winbind was running. un fortunately I was tweaking a file and broke it before i had a chance to backup the file. We know what that means all my work for not. What all items have you taken a look at on configuring the service (just want to get all the information possible that i can have at my hands). Anyways that is the only item that I can tell you. If it helps, good. If not, I can always say that I tried.

Hi barney74,

I had manage to get my samba (redhat ES3) under win2k3 ADS working.
The trick is to upgrade the samba to version 3.0.20b which got it working.

Thanks
