4406529 artificial limit of 10 threads per backend
4516075 LDAP connections could be reused more
4696964 LDAP naming services should support Kerberos authentication
4740951 Need host based authentication options in Native LDAP
4952533 Some backends of gethostby* do not set h_errno correctly
4979596 getXbyY calls should have better buffer mechanism
5028908 /usr/bin/logins accesses free memory deep in nss_getent_u().
5046881 nscd: old-data-ok parameter is not useful, should go away
