A very strange problem I had (people not being put into their secondary groups
on ssh login after switching LDAP to use STARTTLS) boils down to nss_ldap's
configure script failing to detect the presence of pthread_once() on NetBSD.
[It then doesn't register pthread_atfork handlers, but later doesn't manually
detect forks by PID comparison either because that logic tests on the presence
of pthread_atfork, which succeeds. Oh well.]
The test for pthread_once fails in the first place because the test program
doesn't #include <pthread.h> (which I learnt from ws@ does clever things to
make ptherad_once() usable without linking against libpthread).
Even with #include <pthread.h>, it fails once because it does queer things
#define'ing pthread_once itself, and another time by providing a built-in
prototype differing from the real one.
With three patches, the test succeeds and the original problem disappears.
databases/nss_ldap is marked ONLY_FOR_PLATORM NetBSD, so probably a
ssimple-minded patch is OK.
The issue has been reported upstream
(http://bugzilla.padl.com/show_bug.cgi?id=437) over two years ago to no avail.
cd databases/nss_ldap; make configure
look for "pthread_once"
