Notify admins they cannot edit the directory they're logged in through

The UI for the User Directories configuration in Confluence's admin has an operations column.

When you are logged in using a user registered for a directory, this user don't have the privilege to modified the directory it belong to. As stated here:

You cannot edit, disable or remove the directory your user belongs to. This precaution is designed to prevent administrators from locking themselves out of the application by changing the directory configuration in a way that prevents them logging in or removes their administration permissions.

However, there is nothing in the UI that indicates why a directory cannot be edited.

Possible Resolution

I suggest we keep the "Edit" button but grayed it out. When a user hover over the grayed out button add a simple message like "you are logged in via this directory, hence it is not possible to modify it" in the operations column when that is the reason the directory cannot be edited.
