Sneaky LDAP name services

I woke up this morning and found I could not get xscreensaver to prompt me for my password. I couldn’t log in as root. I popped up the temporary head I have on my OpenBSD box, fired up tcpdump, and saw nothing of merit. I also forgot to enable Alt-SysRq on my desktop Linux box. So I hit the reset switch. As it’s coming back up, automount (of all things) hangs for a long time. A few reboots and single user modes later, I find there’s another configuration file, /etc/openldap/ldap.conf that contains the LDAP server’s address. In this case I’d changed only /etc/ldap.conf and not /etc/openldap/ldap.conf. I don’t know how it’s determined which file is used, but once I change the LDAP server in /etc/openldap/ldap.conf, everything started working again. If you can, I guess I’d advise just changing it with authconfig in Red Hat, probably. I’m afraid to run it because I suspect it will overwrite some of my custom settings. Sigh.
