All Components in One Data Center

The simplest deployment includes all required SiteMinder components in a single data center.

The following diagram illustrates:

• All applications in a single data center.
• A Policy Server writing to a master user store. SiteMinder Password Services attempts to perform an LDAP write to the user account on every authentication.

  Important! For more information about multi–mastered LDAP user store support limitations, see the Policy Server Release Notes.

• SiteMinder reading a consumer user store.

  

Consider the following:

• Although not illustrated, SiteMinder supports database clusters configured for write and read–only transactions.
• You can configure multiple components in a data center for operational continuity, redundancy, and high availability.
