some totally incomprehensible reason most distributions (especially
RedHat derived ones) ship with very very very old versions of this
software.  SuSe does quite a bit better.

OpenLDAP 2.2.26-r2

using a BDB or HDB backend (and you should) you need to make sure your
DB_CONFIG settings are reasonable.  If you are using an LDBM backend
then just give up.

Sorry, I am using BDB -- but I have used both LDBM and BDB. Cache settings
and all seem to work good.

addding-for-read?  Can you perform an ldapsearch, without restarting the
DSA?

Well, I can't seem to totally disable it from popping up -- I've added
"name cache timeout = 0" to smb.conf (if I understood that correctly,
thats supposed to stop nscd from starting, maybe not). I "disabled" it by
commenting everything in nscd.conf.

Cool, thats good to know. =)


"Now, the interesting part. If I change the '-g students' to '-g 'domain
users'' everything works fine!

Adding users to 'Domain Users' works, but 'students' does not?

Actually, adding a new group with the first part being "Domain" such as
group 'Domain Studs' works fine. If the group name doesn't have "Domain"
in it, it gets screwed up?"



Thanks for your help,

Marc
