I tried to use Pth with OpenLDAP 2.0.7 on HP-UX 10.20 because this
doesn't come
with threads and had the impression that the Pth support in OpenLDAP is
somehow
broken. Finally I gave up and compiled without threads because I had no
time to
fix it (and we'll drop HP-UX support anyway). One problem I remember was
that
Pth and OpenLDAP disagreed on the return codes. Pth was returning
something
which was meant to be success but OpenLDAP interpreted as an error
return code.
But on Linux you should be fine with LinuxThreads. At least the "make
test"
was successful for me (our production server is on Solaris).
