Doc Type: Bug Fix
Doc Text:
Mozilla NSS initialization functions are not implemented in a thread-safe way. Therefore, if multiple TLS operations were performed simultaneously on an LDAP server, a race condition between the TLS threads could occur. Consequently, the LDAP server terminated unexpectedly with a segmentation fault. With this update, a mutual exclusion (mutex) for Mozilla NSS initialization functions calls has been added to the code, which prevents this situation from occurring. The LDAP server no longer crashes when initializing a TLS connection.
