OpenLDAP and MySQL

[Russell Handorf <rhandorf@handorf.org>]

Hello all,

I've been researching and attempting to get OpenLDAP and MySQL to play 
nice together now for a little over a week. Unfortunately, I cannot get 
them to do so (I've even threatened time out, but alas, they still 
misbehave).

I've been following the HowTo here: 
http://www.flatmtn.com/computer/Linux-LDAP.html only to find it lacking 
major detail and non working config scripts. I've since started 'on my 
own' and now slapd starts without any errors now. The problems are:

1. Short of no errors, I cant get any data INTO or OUT OF the LDAP server
2. As such, no user info can be authenticated
3. GUI's (yup, I've even tried them) such as phpLDAP have vague errors 
such as:
   Could not bind to the LDAP server.

   LDAP said: Undefined attribute type
   Error number: 0x11 (LDAP_UNDEFINED_TYPE)
   Description: The attribute type specified is invalid.

My end goal for the first step is to have LDAP use MySQL as the DB, and 
to authenticate SAMBA clients this way. The DB is necessary because I 
already have a big database of user accounts/passwords for 
IMAP/POP/SASL/Postfix that would be way too much of a pain to migrate 
the accounts, then how they would be stored on the file system (phase 
two is to have that username/password base authenticate the SAMBA 
clients). Would anyone mind pointing me in the right direction with 
getting LDAP-MySQL to work?

System: Slackware 10.0
OpenLDAP: 2.3.22
Samba: 3.0.22
MySQL: 4.0.24
MyODBC: 2.50.39   (3.51.12 compiled with way to many warnings and exited 
on a few vague errors)
libiodbc: 3.52.4
