 For Linux\OSX you must ensure you have the latest OpenLDAP client libraries installed from http://www.openldap.org
 
 For Linux you must also ensure that the appropriate [symlinks for `libldap.so.2` and `liblber.so.2`](linux.md) exist.
+If you're using `2.4` or older version of `libldap`, the symlink must point to `libldap_r`, the threaded version of the library,
+otherwise async methods might cause unpredictable errors. Starting with `2.5` `libldap` is multi-threaded by default.
 
 It works with any LDAP protocol compatible directory server (including Microsoft Active Directory).
