On two RHEL4u5 lab machines, LDAP authentication stopped working. The only thing that was done was DHCP was enabled on a previously-unconfigured interface. That messed up ntpd.conf, so I know that weird stuff was going on. Anyway, all attempts to log in with an LDAP user result in ldap_simple_bind: Can't contact LDAP server However, the machines can ping the LDAP server, and nmap shows 389 and 636 as open. /etc/ldap.conf has not changed. /etc/nsswitch.conf has not changed. I ran "authconfig" and the server line was empty, so I filled it in. No dice.
I am completely stumped.

What do your slapd logs show? Can you still use ldapsearch? What slapd version do you have?
