LDAP-UX Client Services B.05.00 Administrator's Guide
5.4 Adding a directory replica
Your LDAP directory contains configuration profiles downloaded by each client system and
name service data accessed by each client system. As your environment grows, you may need
to add a directory replica to your environment. LDAP-UX can take advantage of replica directory
servers and the alternates if one of them fails. Follow these steps to inform LDAP-UX about
multiple directory servers:
1. Create and configure your LDAP directory replica. For the HP-UX Directory Server, see the
HP-UX Directory Server deployment guide.
2. Edit an existing profile and modify the defaultServerList or preferredServerList attribute to
specify a replica directory server. See Section 5.12 (page 183).
See Appendix B (page 349) for a description of the defaultServerList or preferredServer
attribute.
3. On all clients that are to use the replica server, edit the start-up file, /etc/opt/ldapux/
ldapux_client.conf, to refer to the replica host. Modify the LDAP_HOSTPORT line to
specify the replica server.
4. After modifying an existing profile, each client that regularly downloads its profile
automatically will get the changes as scheduled. SeeSection 2.5.8 (page 113).
NOTE: Client systems using an LDAP directory replica may not be able to modify the directory
replica. In this case, the passwd command will not work on those systems. They can use the
ldappasswd command described in Section 7.4.2 (page 294).
