Hi,
I'm trying to integrate an existing linux environment with a Windows AD
environment. All my users are already in AD with valid rfc2307
attributes defined so I need a way to authenticate my users using
username, uid, gid, shell and homedirectory from AD. I've been using
Kerberos+LDAPs before but that requires a dummy AD user hardcoded with
username and password in /etc/ldap.conf which is making me icky.
According to the man pages it looks like idmap_adex should do the trick
for me, however I can't get things to work. (see config files below)
Running 'wbinfo -u' does give me a the list of valid users, however
'getent passwd' waits a second after displaying the local users and then
just gives me back the command-line prompt.
In /var/log/samba/log.winbindd-idmap I see:
==================
...

LWI: Failled to connect to cell "dc=MY,dc=DOMAIN,dc=COM"
(NT_STATUS_NO_LOGON_SERVERS)
==================
Note that the adex module is available on the filesystem:
==================
r...@ubuntu:/var/log/samba# locate *adex*
/usr/lib/samba/idmap/adex.so
/usr/share/man/man8/idmap_adex.8.gz
==================
What am I doing wrong?
Thanks in advance,
Nico
