[Samba] net user with no results

[Lapin(c)]

Hi team,

I'm running a Samba3.0.4/LDAP PDC configuration on HP-UX.
Everything is fine except for 'net' command.
for net user and net group, I dont have neither errors nor users list !
others net request are fine, and I can connect with authentication with smbclient.

any idea ?

Many thanks,

Fred
