Hi, I have succesfully installed the latest version of samba (2.2.7a.tar.gz) with winbind support and it seems to work. If I run getent passwd or group I can see local and remote (NT4) users and groups but, if I create a new user linux login with a NT group, useradd says: [linux] useradd -g DOMAIN+group -d HOME DIR -s /bin/false USER useradd:unknown group DOMAIN+group It not should use nsswitch.conf to check for groups? My nsswitch.conf file is: passwd files winbind group files winbind With getent it works but useradd not! I saw also in /etc/pam.d/ there is a useradd configuration file, so I tried with several combinations to add pam_winbind.so module but without success. useradd file. I have not any ideas for solving this problem. Can anyone help me? Thank you very much for yours collaboration, Gabriele.
