nss-pam-ldapd is actively maintained while nss_ldap/pam_ldap are not updated in a while. nss-pam-ldapd is more robust too (I had a similar problem like https://bugs.archlinux.org/task/33672 that didn't occur with nss-pam-ldapd; and according to that bug report actually a nss_ldap/pam_ldap setup is simply broken). According to the author ( http://arthurdejong.org/nss-pam-ldapd/) nss-pam-ldapd is faster and more easily to debug (I didn't measured performance, but indeed nss-pam-ldapd is easier to debug, since it's service nslcd have a nice log output). I think Fedora and Mageia uses nss-pam-ldapd for default instead nss_ldap/pam_ldap. Even our Wiki (https://wiki.archlinux.org/index.php/OpenLDAP_Authentication) is recommending nss-pam-ldapd instead of nss_ldap/pam_ldap (actually, if you follow our Wiki using nss_ldap/pam_ldap you will have a non-working LDAP setup). So I suggest to drop nss_ldap/pam_ldap to AUR and put nss-pam-ldapd on [Extra] repository. -- Thiago Kenji Okada <thiago.mast3r@gmail.com> PGP Key: EEC09705
