I know this problem has been addressed before, but I was unable to find an answer that made any sense. I have openldap-2.0.21-1 on a RH7.2 sys with pretty much the defaults on the slapd.conf file (the only parts changed were adding my domain name to the examples) I can post the slapd.conf if needed, but as stated earlier it's the RH default slapd with only my domain name added in. Ok, when I run: slapd -d 256 I get: slapd -d 256 daemon: socket() failed errno=97 (Address family not supported by protocol) daemon: bind(6) failed errno=98 (Address already in use) daemon: bind(6) failed slapd stopped. connections_destroy: nothing to destroy ON previous mails, I see people stating that another process is using port 389. I then ran netstat -nat| grep 389 and saw: tcp 0 0 0.0.0.0:389 0.0.0.0:* LISTEN I then killed ldap with: service ldap stop and reran netstat to see if that port was still in use and it wasn't: Netstat -nat|grep 389 returned no results. I then checked to ensure all firewalling programs were killed: service ipchains stop service iptables stop service portsentry stop I then restart ldap (service ldap start), try to use ldapadd, and as usual, nothing. I'm at a loss here, if there is anyone who can help me it would be greatly appreciated.
