Description Yanick Quirion 2006-10-10 10:13:07 UTC
Dear Support,

I'm having problem with samba 3.0.23c. The smbd process will crash when I have the following definition for a specific share:

[user1]
        comment = User1 Home Directory
        path = /u/management/user1
        valid users = domain+user1,sher+user2
        force user = domain+user1
        force group = sher+management
        read only = no
        create mask = 0660
        directory mask = 0770
        nt acl support = yes

After making tests, I've found that the problem is caused by the "force user" and "force group". When I comment those lines, I can access the share drive.

Here is a part of my log.smbd:

With the version 3.0.21b I do not have this problem. I'm using the same smb.conf file I was using with 3.0.21b.

Please keep me in touch regarding this issue.
