Using the wbinfo utility, I have been able to maybe narrow the problem down. Original problem still exists, however. [root@geronimo nsswitch]# wbinfo -a HCCMHMRC+scripttest%scripttest plaintext password authentication succeeded challenge/response password authentication failed Could not authenticate user HCCMHMRC+scripttest%scripttest with challenge/response I am using RH 7.1 and Samba 2.2.2 with winbindd. While it generally seems to be working, group permissions are giving me a problem. Group ownership for a specific directory is established as 10007, which translates to my NT domain's Domain Admins group. I am trying to access the directory through a share using Windows 2000 workstation. The group has RWX permissions yet, as a member of that group, I can't save a file to that directory. I have to change the world to RWX. Then when I save a file, it shows the owner as nobody. The smb.conf pertaining to that share looks like this: [Intranet] path = /usr/local/apache/htdocs/ read only = No guest ok = Yes browseable = No It appears that I may have a disconnect between winbindd and Samba, but I don't know what. Any ideas? I'm not a member of the list, so please respond privately. Thanks. Carl Carpenter IT Manager Hill Country Community MHMR Center "Hiroshima 1945, Chernobyl 1986, Windows 2000"
