After a lot of banging my head against a wall I finally figured this one out. If figured I'd post the solution in case someone else runs into the same problem.
I found the solution when I googled this http://www.mail-archive.com/php-b...@lists.php.net/msg02201.html Someone in the php world had a similar problem. It turns out that openldap and oracle both have functions called ldap_modify_s. Occasionally my program would call the oracle version instead of the the openldap version and promptly seg fault. The solution was to put LD_PRELOAD=/usr/lib/libldap.so export LD_PRELOAD into /usr/local/apache2/bin/envvars On Feb 17, 3:42 pm, molhacker <wpwalt...@gmail.com> wrote: > I've been running into a very frustrating situation with a seg fault > in Apache when authenticating Django usingLDAP.
