Feedback on usability would be helpful at this point. If anyone wants to jump in and get a real manpage started, that would be nice too. The main objective here was to eliminate the libldap dependencies/clashes that the current pam_ldap/nss_ldap solutions all suffer from. A secondary objective was to allow for the possibility of more sophisticated caching than nscd provides. (E.g., run slapd back-ldap + pcache on each node.) Of course, you can also completey eliminate cache staleness considerations by running a regular database with syncrepl. And of course, another major objective was to allow all security policy to be administered centrally via LDAP, instead of having fragile rules scattered across multiple flat files. As such, there is no client-side configuration at all for the pam/nss stub libraries. (They talk to the server via a Unix domain socket whose path is hardcoded to /var/run/nslcd/). As a side benefit, this can finally eliminate the perpetual confusion over /etc/ldap.conf vs /etc/openldap/ldap.conf. User authentication is performed by internal simple Binds. User authorization leverages the slapd ACL engine, which offers much more power and flexibility than the simple group/hostname checks in the old pam_ldap code. At this point some cleanup is probably still needed, and merging the nslcd bits back into Arthur de Jong's code base is still underway. (Which means this code will be showing up in Debian soon, and I will be recommending it to the Ubuntu guys next month as well.) -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
