 Description   

Description

See TSWRITING-1272 which advised ldapForceMultiThreadMode be enabled for EL7.5+ when using libldap (not libldap_r) but this isn't yet documentated.

I guess it should be listed just before https://docs.mongodb.com/manual/reference/parameters/#param.ldapUserCacheInvalidationInterval

This flag allows MongoDB to perform concurrent LDAP operations, and is required to use LDAP connection pooling. Concurrent use is disabled by default on many platforms because earlier versions of platform provided libldap were not safe to use in a concurrent fashion. You may enable this flag if you are certain that your instance of libldap is safe to use in this mode.

Yes . I agree . This should be documented . We observed a significant drop in volume of slow calls (more than 80%)  to the LDAP server on stress test volumes because of this parameter .
