Hello all i have successfully upgrade an old PDC samba server (debian woody) to a new centos 5. Everything works fine except for one thing 1- i'm unable to add new computer to domain except with the root users. With others installations all users in the group "Domain Admins" was able, now i get tis error: sh: /usr/sbin/useradd: Permission denied [2007/12/18 17:33:26, 0] passdb/pdb_interface.c:pdb_default_create_user(329) _samr_create_user: Running the command `/usr/sbin/useradd -g computer -c "Workstation (genoveffo2$)" -M -s /bin/false "genoveffo2$"' gave 126 After a new group map "Domain Admins" -> root group the error is: useradd: unable to lock password file [2007/12/18 17:42:49, 0] passdb/pdb_interface.c:pdb_default_create_user(329) _samr_create_user: Running the command `/usr/sbin/useradd -g computer -c "Workstation (genoveffo2$)" -M -s /bin/false "genoveffo2$"' gave 1 useradd: unable to lock password file [2007/12/18 17:47:10, 0] passdb/pdb_interface.c:pdb_default_create_user(329) _samr_create_user: Running the command `/usr/sbin/useradd -g computer -c "Workstation (genoveffo2$)" -M -s /bin/false "genoveffo2$"' gave 1 The right of the users in "Domain Admins" (alessice) are not sufficient.
