For ldap, as long as "getent passwd" shows your user and computer
accounts, that is what really matters.
Is samba is looking for users in your ldap base (e.g.
dc=univ-orleans,dc=fr) ? If so it will see all users. However it will
not distinguish between users in ou=people or ou =systeme. Any users
you wish to have administrator privledges should be added to the "Domain
Verify that you have a group mapping for domain admins.
# net groupmap list | grep "Domain Admins"
Domain Admins (S-1-5-21-XXX-XXX-XXX-512 ) -> Domain Admins
I have a unix group in ldap called "Domain Admins" - my unix system
allows groups with spaces in it. I don't know if yours will.
net rpc group MEMBERS "Domain Admins" -U Administrator
However, even if you are a system administrator, you should not
normally be logged in as an admin-equivalent. Instead, you should
only use an admin-equivalent account when you specifically need it.
If you wish to allow some users to add machines to the domain but not
give them full admin privlegdes you should be able to grant the
I don't understand the "admin99" issue. You have a samba user called
"admin99", and you use that to join a Windows machine to the
domain? Where are you opening a terminal from? What does "pbdedit
