LDAP

This page desperately needs to be filled out or brought up to date. If you're familiar with the operations of this part of the site, please help!

FIXME: There's almost no server info here

FIXME: What about client startup when servers are flaky?

Hosts should be to use LDAP for users and some other stuff.

Things are moving to NIS... very, very slowly...

setup LDAP client on new machine

• run /home/wikipedia/bin/setup-ldap
• copy zwinger:/etc/ldap.conf to the new machine

LDAP server is on srv1 (master) and srv2 (slave). failover should be automatic. to add new users, add them on srv1, then run ldapsync. srv2 will update automatically.

Overload

If the local caching daemon nscd dies on clients, the server can get badly overloaded and logins can fail.

If necessary restart it sitewide. :P

Server logging

slapd's logging stuff goes to a channel on syslog that's not logged by default. On a new server, you may have to manually edit syslog.conf and add something for local4.*

Then set an appropriate loglevel in /etc/openldap/slapd.conf
