Google shows quite a bit of information about this and it seems
related to not clearing errors before using the dl* methods.

Shows an (old) patch for Samba3 to add it.

http://www.freebsd.org/cgi/cvsweb.cgi/ports/net/samba3/files/Attic/patch-lib_module.c?rev=1.1&content-type=text/x-cvsweb-markup

Seems like this patch is required for auth/auth-module.c

This is against RC7.
