You can change the settings for existing domains from the Domain Management page. You can also convert an existing enterprise domain to a hybrid domain.
To change the authentication information for an enterprise or hybrid domain, click the appropriate authentication name at the bottom of the page. On the Edit Authentication page, change settings as required. (See Authentication settings.)
To change the directory information for an enterprise domain, click the appropriate directory name at the bottom of the page. On the Edit Directory page, change settings as required. (See Adding directories or custom SPIs.)
If the enterprise domain that you are converting does not contain directory settings, any LDAP authentication settings are lost.
