Running under FreeBSD port of LinuxThreads

LinuxThreads are preemptive and hence are not safe to use with OpenLDAP 1.x. See also:

Is OpenLDAP thread safe?

After installing the LinuxThreads port for FreeBSD (available at <http://lt.tar.com>), OpenLDAP can be configured to use LinuxThreads as follows:

Version	Commands
1.2	`env ol_cv_linux_threads=yes CPPFLAGS=-DLINUXTHREADS ./configure --with-threads=posix`
-devel	`env CPPFLAGS=-DLINUXTHREADS ./configure --with-threads=posix`

OpenLDAP can still be configured to use FreeBSD "user threads" as follows:
Version Commands

1.2 env ol_cv_kthread_flag=no ./configure --with-threads=posix

-devel env ol_cv_pthread_kthread=no ./configure --with-threads=posix

You must ensure that all libraries linked OpenLDAP threaded applications are compiled appropriately to support LinuxThreads. Libraries compiled with "user threads" are unusable.
