There are several situations in Security Manager when editor for managing users accounts is not available. In these cases, a message explaining why the editor cannot be displayed is shown in its place. Possible messages are as follows:
To view the list of users select a connection from the drop-down list on the window toolbar or click Refresh
No connection is selected, and there are no objects in the user list (i.e. there is no user to select).
You do not have enough privileges to view users. Select another connection or change connection settings and click Refresh
User has no rights to read security metadata.
Cannot show editor because no users are selected or objects of different types are selected
Different types of objects are selected in the tree or if host is selected.
