Description Zing 2008-07-11 20:22:54 UTC
Description of problem:
I can crash openldap fairly easily using nssldap.  Sometimes it's immediate,
sometimes I can get through 100's of queries (using the "id" command) before
openldap segfaults.

It looks like it always bombs in is_ad_subtype though. 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. the openldap directory populated with about 1500 users (ou=People,..) and
about 1500 groups (ou=groups,...)
2. setup system with authconfig to use ldap name lookups.
3. i have a script which calls "id <userid>" for all the users.

Actual results:
either immediately or eventually openldap segfaults.

Expected results:
no segfault.

Additional info:
i'll attach some more info...

Comment 3 Zing 2008-07-12 19:55:07 UTC
Well, I built openldap-2.4.10-2 from rawhide and so far I've done a couple
thousand queries with no segfaults.  Possibly the internal bdb upgrade to 4.6
helps/fixes the problem.

Comment 4 Jan Safranek 2008-07-16 11:34:04 UTC
I'd rather not rebase the internal bdb in middle of Fedora lifecycle, but I can
try to update openldap to openldap-2.4.10, which should fix the issue. I created
a test build for you at, could
you please give it a try? Let me know if it works for you.

Comment 5 Zing 2008-07-17 02:26:11 UTC
Your right, that works. thanks.
