No, it's a lot easier than that in OpenLDAP.

I have ported Mozilla/Thunderbird/Seamonkey to use OpenLDAP already.

MozLDAP provides a single library that is moderately thread-safe. It uses 
thread-local-storage in a few places as needed. OpenLDAP provides two separate 
libraries, one non-threaded and one threaded. If your app is threaded you'll 
need to check which library you've linked and how you use the LDAP * session 
handles.

For the most part it's a pretty easy transition.
