If you are not logged in, go to the iFolder Management Console, click Global Settings, enter your administrator username and password, then click login. For details, see Logging In to the iFolder Management Console.
Click Global Settings > User LDAPs.
The User LDAPs page lists the existing LDAP servers you have identified to iFolder.
Click Delete All.
This removes the LDAP objects that are associated with all of the LDAP servers from the LDAP directory. The LDAP objects can no longer be managed through the iFolder Management Console. You must add LDAP servers to the list so that iFolder can authenticate users.
