Re: [K12OSN] Authenticating From an OSX Server



Bruce -

I just went through this, so if you look back in the archives a bit, find
messages from me (cbutler shoreschool org) with subject "Authenticate to
OS X Open Directory" for my problems and successes.

The k12ltsp wiki has an entry under the "Interoperability" section
  http://www.k12ltsp.org/phpwiki/index.php/Technical%3AIntegrateWithOSX
that really is all you need.

The one thing missing from that is that gdm-binary needs to be restarted
for it to catch the changes made in authconfig.

A brief summary our our setup:
helios: OS X 10.3.4 Open Directory Master
saturn: OS X 10.3.4 Home Directory Server (all home directories on a fiber
channel attached XRAID)
ltsp: K12TLTSP 4.1.1 two-NIC setup with thin clients on 192.168.0.0/24
network.

With WGM I have set one of our home directory mounts to be shared via NFS
to the K12LTSP server (I'm still in testing mode, so I am only sharing the
faculty mount at this time.)   For our setup, the path on our server to
the home directory folder is
  /Volumes/SaturnRAID/Home
so the mkdir command I had to do on the LTSP server was
  mkdir -p /Network/Servers/saturn/volumes/SaturnRAID/Home
and the mount command looked similar
  mount saturn:/Network/Servers/saturn/volumes/SaturnRAID/Home \
    /Network/Servers/saturn/SaturnRAID/Home

The authconfig work was easy - just take a look at the Open Directory
settings on your Open Directory Master (in Server Admin) to figure out
what the LDAP Base DN is.

Then, the missing step:
 RESTART GDM
I figured this out after three days (I actually restarted the server
itself).  I think there is a script "gdm-safe-restart" that will do this
for you.

Now, I can log in to a thin client in the 192 network with my OS X
username/password and my OS X home directory shows up as my LTSP home
directory.  Even more fun, from any Mac on campus, I can run
  /usr/X11R6/bin/x -query ltsp :1
and get an X session running with access to all the fun Gnome stuff.

Hope this helps, and please, if you have any questions, feel free to ask.
