Multiple LDAP domains

You can establish multiple network domains within the same forest or for completely non-trusted domains.

The recommended method for handling multiple domains is to create a separate LDAP server record for each domain. Each LDAP server record must point to a domain controller for that domain. This means the local network must allow connections to each of the domain controllers.

After expanding to more than one network domain, it is critical that you identify unique LDAP attributes for the application usernames and import coalesce values. A common unique coalesce attribute for Active Directory is objectSid. Unique usernames may vary based on the LDAP data design. Common attributes are email or userPrincipalName.
