I'm wondering if the bind_policy and bind_timelimit would help here.
Also this may not per say be a development issue so I suppose I should
move this discussion off the devel list, however, if libnss-ldap is
having this problem due to possibly a libc issue and yes now that you
mention it I did see that in the debug log, would not pam_ldap also
experience that same thing?
