[rt-users] LDAP and autohandler

[Michael K Brown]

Hi All!

I'm trying to get our new RT installation (2.0.11) running with LDAP, and I
could really use some help. My Unix knowledge is pretty good, but I'm
definitely not a programmer!  I'll get to my problems in a minute.

Jesse,

Having gone down the "Clarify" road (courtesy our IS department), and turned
to RT2 instead, I really have to say that you have a wonderful product here.
RT2 does more in my application (supporting an R&D environment of 500 users,
with a support team of 6 lab techs) than "Clarify" could ever do.  I'm
really impressed with RT, and I haven't even got the mail gateway up yet
(waiting on IS to point my e-mail addresses to my server).  Lots of people
seem to need or want LDAP authentication; I'm wondering if you could build
it in to the base system, and if people need it, they could copy over the
appropriate files much like nsswitch.conf.
 (i.e. cp autohandler.LDAP autohandler  and cp config.LDAP config.pm).  Just
a thought...

Now, on to my LDAP woes... If anyone has a working version of this that
they'd like to post or e-mail me, your help would be greatly appreciated!
I'm under the gun to get this running ASAP, because my 5 team members and I
are just drowning in work!


I've put in the LDAP mod for External Users into config.pm.  I've also tried
the autohandler mod shown in the following link (I have e-mailed the
contributor off list, and I'm hoping he's still around to be able to
answer).

I would like to go with the autohandler route as opposed to just turning on
the WebExternalAuth, as RT's login screen is much nicer, and the ability to
'logout' is a requirement in my lab environment, where many users share
workstations.

The problems I'm having with the autohandler mod is that root can't log-in
(mason errors) and something's not quite right with our LDAP
authentication... I keep getting
 Error
Login failed: LDAP_NO_SUCH_OBJECT

I think my LDAP problem may be in this line

my $dn = "uid=" . $user . ",o=our company, c=ca";

but I can't see what's wrong with this.


Here's the mason error for root logins:

error in file:   /usr/local/rt2/WebRT/data/obj/STANDARD/autohandler

Any help would be greatly appreciated!  Thanks for your time, and for wading
