To remove a security manager from the Directory server's security manager list

Click Security under Configure on the menu on the left-hand side of an Enterprise Server Administration Web page.
Click Directory Server.
In the Security Manager List, select the definition that you want to remove by clicking the relevant radio button in the Select column.
Click Remove.
You are now prompted to enter an administrator username and password. Directory Server must be able to verify this user when the security manager has been removed from the list. That is, where there are other security managers in the list, the user account must either exist in at least one of those security managers. Where there are no other security managers in the list, Directory Server will use its legacy security model, and the user must be defined within that model.

If Directory Server cannot verify the user, the security manager will not be removed.

Note:

This only removes the definition from the list, it does not remove it from the security manager pool.
Where you are running MF Directory Server with Restrict administration access set, and you make a change to the security manager list that it uses, you are challenged to supply:
1. a set of credentials that are valid with the configuration prior to the changes being applied
  and
2. a set of credentials that will be valid with the configuration after the changes are applied. This is to ensure that you can still access the MF Directory Server screens.
If appropriate credentials are not supplied or are not valid, the changes will not be applied.
