The author of nss_ldap and pam_ldap officially abandoned those packages ~9 years ago. Support
for those packages was redirected from the authors at PADL.com to Symas.com back in 2007 or so,
and we (Symas) have promoted nss-pam-ldapd and OpenLDAP nssov since 2010.

nss-ldap is not mature, it is dead.
