Server is MS Windows 2000
What is IDMU ? We have made sure NIS Extension is installed and that
"tunix" uid/gid have been set to 10000/10000. But others users (groups)
have not been set, especially "Domain Users" (Utilisateurs_du_domaine in
my log). Setting its GID value in UNIX Tab solved the issue !
May be the Wiki could stress on that particular point.
Thanks for your help.
