I'm having trouble in determining what mutex is related to what data in libldap's structures. For example, as far as I understand, lconn_refcnt in LDAPConn is tested and even modified without expressly locking any mutex. Logically, it seems to me that ld_conn_mutex should be the one. Could anybody please confirm this or provide insight?

I think this is a -devel thread.

The last time I looked, ld_res_mutex is always held when touching lconn_refcnt. That was before your most recent commits.
