From 72ba4cfb715001d30a6e48a2d7012f060f29d684 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Use -lldap_r instead of -lldap -lthread. 	Likely broke
 things for non-posix threadings....

Update -lldap_r implementation to:
	remove attribute support
	hide thread detachment
	provide concurrency accessors
	provide initialization function
	fix gethostby{addr,name}_r codes (not coverred by HAVE_REENTRANT_FUNCTIONS)
Update servers/libraries to use ldap_pvt_thread_ calls.
Cleanup server codes (no #ifdef HAVE_PTHREAD_THIS or _THATs)!
Removed -llthread
