You must link all LDAP directory identity sources to the system. After linking, all users in the identity source can be viewed and managed through the Security Console. Users are visible in the top-level security domain by default, but you can move them to other security domains as necessary. Additionally, you can configure the system to place users from the identity source into a specific security domain automatically. For more information, see Default Security Domain Mappings.
Before you begin
You must be a Super Admin.
If you link an Active Directory Global Catalog, you must also link each identity source that replicates user data to that Global Catalog. For example, if identity sources IS1 and IS2 replicate information to Global Catalog GC1, and you link GC1 as an identity source, you must also link IS1 and IS2 to the system.
In the Security Console, click Setup > Identity Sources > Link Identity Source to System.
From the list of available identity sources, select the identity source that you want to link , and click the right arrow.
