When the slapd is down but the server is up, failover is immediate because the server will actively refuse connections on the LDAP port. When the server itself is down, connections timeout only when TCP times out. You can force a shorter timeout in the clients using ldap_set_option with LDAP_OPT_NETWORK_TIMEOUT. -- Howard Chu Chief Architect, Symas Corp.

I took the slapds down on the first server and the clients seemed to failover to the second server until I actually shutdown Linux on the first server. Then a small number clients started to hang on LDAP requests. These problems did not show up in my initial testing. Is there something else I need to configure? Using LDAP for people, groups and automounts. LDAP server are Red Hat 7.3 with openldap.2.0.26 with server side TLS. Clients are Red Hat 7.3 with openldap-clients-2.0.27-2.7.3.i386.rpm Gerry
