Wanted to test the openldap server so I wrote a script that loops through
all the logins we have.  For each login a c program does a getpwnam call and
returns the password information.    When I run this script openldap will
die after about 1000 entries with a segmentation fault.  If I do an
ldapsearch for the same information, openldap stays alive and returns
everything.  We have about 1,500 logins.  Any ideas?

Clients are RH 7.1 with openldap-2.0.7-14 (Red Hat standard issue).
Server is RH7.1 with openldap-2.0.11.
