As I said in my previous message - when we're forced to use a

protects calls from our code. If there are other threads in other
software calling the same libc functions, they will not be guarded by
our mutexes, and so their behavior is indeterminate. This is one reason
why we cannot guarantee support for libldap_r in arbitrary code.
Well, it seems to me that you could garantee that, if libldap_r only
used thread-safe functions. A configure flag to request libldap_r build
to use only thread-safe function or fail would be very helpful.
Feel free to submit a patch.
Note that such a flag doesn't enhance libldap_r's usefulness to slapd in
any way, so there's very little motivation for anyone else to create
this patch for you. If you want it, write it.
