Hi!

Thank you for your answer.
Actually it is still RHEL 5.2, i just have mispelled it.

# net ads testjoin
Join is OK

# net ads info
LDAP server: 10.20.30.40
LDAP server name: HUBUDC001.$DOMAIN
Realm: $KRB-REALM
Bind Path: dc=$DOMAIN,dc=$SUFFIX
LDAP port: 389
Server time: Fri, 06 Feb 2009 09:49:59 CET
KDC server: 10.20.30.40
Server time offset: 0

This is the info that I caould extract, the samba share is on a windows
machine that I don't have any kind of access to (except smb), and the
domain controller is on windows I'm pretty much sure about it. But don't
know any further infos.
