Description Rich Megginson 2012-04-24 21:01:47 EDT 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/348

If multiple threads call ldap_initialize at the same time, the program will crash.  We have seen this in the server and in threaded tools such as ldclt on multiple platforms with openldap 2.4.24-2.4.30.  Threaded programs need to have a mutex around calls to ldap_initialize.

This can be reproduced by increasing the number of threads used by ldclt - you should eventually hit the crash - or by configuring the directory server with many (8) replication agreements, and repeatedly stopping and starting the server.  It will eventually crash at startup.
