Authenticating Linux against OSX LDAP directory

[ link: osx-ldap-authentication | tags: osx linux ubuntu ldap | updated: Mon, 30 Jun 2008 09:21:15 ]

I was recently asked by a colleague, and now also a client, to look over the LDAP configuration on his Ubuntu boxen. He was having issues with the root account. The problem turned out being that the Ubuntu box was trying to get the root authentication from LDAP. It successfully found an LDAP account on the OSX LDAP server, but was unable to login since that account is disabled. The solution was to filter out the root account from the LDAP reply using the pam_filter directive in /etc/ldap.conf. Jay was also kind enough to document his setup for others that are trying to accomplish a similar task.

side note: Jay briefly showed me his OSX/Linux integration... looks pretty cool. Particularly the LDAP directory and automount of OSX exported volumes for users. OSX seems to make certain things really easy.

Ok, so in last eppisode we looked at how my Debian/testing upgrade of slapd killed my slapd install because I was using two incompatible schemas.

Now, I will show you how to limit what accounts are accessible to pam_ldap module on each host.

stupid ldap

[ link: ldap-upgrade-to-2.3.23-brakage | tags: ldap linux debian | updated: Thu, 27 Jul 2006 12:50:09 ]

For some very stupid reason I decided to upgrade my fileserver, which happens to run my ldap database as well.

Setting up slapd (2.3.23-1) ...
  Backing up /etc/ldap/slapd.conf in /var/backups/slapd-2.2.26-5... done.
  Moving old database directories to /var/backups:

  Backup path /var/backups/dc=jukie-2.2.26-5.ldapdb exists. Giving up...
dpkg: error processing slapd (--configure):
 subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
 slapd
E: Sub-process /usr/bin/dpkg returned an error code (1)

Frig!

ldap on debian

[ link: 20050925130002 | tags: linux debian ldap | updated: Tue, 16 May 2006 09:56:40 ]

I've started writing a debian authentication from ldap tutorial. Here is the unfinished text:

  • Ldap Authentication on Debian

    I've seen a much more ass kicking one on Planet Debian recently from Edd Dumbill. Here is a link:

  • Turn your world LDAP-tastic, and
  • Visual LDAP administration tools - a recent fallowup
  • LDAP authentication (part 1)

    [ link: 20050108095026 | tags: linux debian ldap | updated: Tue, 16 May 2006 09:56:40 ]

    .
    
    Wasted some time this week converting my server to LDAP directories and
    renumbering UIDs/GIDs to the "Debian numbering ranges" from the RedHat
    ranges that I have lived with for 7 years -- I have a lot of data to
    migrate over to the new IDs... data is intact.
    
    LDAP is so ugly after you used SQL, and is a bitch to setup, but after a
    few hours I managed to get it working with PAM and NSS.  I will have to
    document my steps because I had to read ~10 documents on the web to
    finally get things working -- the Debian packages do not do all the work
    for you in this case. 
    
    I still don't have my desktops setup the way I want, but the vservers
    can feed from LDAP for user IDs (for ssh logins and lookup when you do
    things like ls -l or id).  And there is always the issue of what is to
    be done with the mobile machine...  I think I will just use ssh-fs 
    (via fuse) and not worry about having a common .
    
    Stay tuned for further details :)
