You can view and update the list of domains that sync to the Workspace ONE Access directory from the directory's tab. For directories of type LDAP, or Active Directory over LDAP, you cannot change the selected domains. For directories of type Active Directory over Integrated Windows Authentication, you can update the list of domains.
Tip: Choose trusted domains one by one instead of selecting all the domains at once. This ensures that domain save is not a long-running operation that can potentially time out. Choosing domains sequentially ensures that the Directory Sync service spends time trying to resolve a single domain only.
Note: For Active Directory over LDAP directories that have the Global Catalog option selected, the Domains tab does not appear.
