Basic Requirements for LDAP Failover
The following basic requirements must be met before configuring LDAP failover:
An LDAP failover capability requires two or more LDAP servers in a failover group.
These LDAP servers must hold the same content, or at least have the same content in the parts of the directory tree used or searched by Windchill.
Changes made to one server in the group must be quickly applied to all other servers in the group.
All servers in the failover group must use the same bindDN and password for administrative access.
Meeting the requirements requires the use of multi-master replication.
Then, make the Windchill configuration changes described in LDAP Failover Configuration Changes.
