If seen this happen when there are dns problems. You may want to check out /etc/resolv.conf and ensure all is okay there.

Recently, anytime a user tries to log in they are unable to. I managed to log in as root and try to do any command that requires looking up a username, and the system hangs. Even doing an 'ls /home' hangs. I've determined it has something to do with nss...if I remove ldap from nsswitch.conf, the system responds, but user ids are not translated to user names. /var/log/messges doesn't show much, just: Mar 30 15:43:38 sapphire ls: nss_ldap: could not search LDAP server - Server is unavailable Mar 30 15:43:38 sapphire ls: nss_ldap: reconnecting to LDAP server (sleeping 4 seconds)... Mar 30 15:43:42 sapphire ls: nss_ldap: reconnecting to LDAP server (sleeping 8 seconds)... Mar 30 15:43:44 sapphire ls: nss_ldap: reconnecting to LDAP server (sleeping 16 seconds)... Mar 30 15:44:00 sapphire ls: nss_ldap: reconnecting to LDAP server (sleeping 32 seconds)... I haven't changed anything on this system and have no idea why this started. Its a fully patched RHEL 5 box. Any ideas where to start looking? -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
