An administrator can can delegate administration allowing a limited administrator to create and manage users in their group, and assign folders that they themselves have access to. We'd call this administrator a Restricted Admin account.

First need to create a user Group with the corresponding Group Template account. This latter is to be assigned some top level VFS directory under which the group member users will have their own working directories later on. The same VFS is to be granted to the Restricted Admin, these two settings together will confine both the admin and the group members under that directory, with no escalation possible. This only works for local files.
11.2.2_10+ Supports Connection Profiles at User Manager too. Using Connection Profiles the Restricted Admin can assign remote locations to the group members.




Then grant the admin on the Setup Roles panel the Remote User Only Administration (Limited) role permission, the group name to administer, and eventually restrict the admin roles even further on the Setup Permissions ( limited admin only) panel.


In CrushFTP v10 we now support multiple groups for the same admin. Each group has to have designated it's own Group Template account, and the VFS directories assigned to these need also to be granted to the Restricted Admin, or this latter to be pointed to an upper-level directory.
With the Restricted Admin scenario functional:
1.) If the user is not a member of the group, the change is rejected.
2.) If the home folders being specified are not a subfolder of the home directory that the group user can access, the change is rejected.
3.) If the change involves adding an event to a user that specifies a "plugin" action, the change is rejected.
4.) Other admin escalation permissions are denied too.
These are done to enforce security and prevent privilege escalation. Any attempted violation is logged in the server log for audit purposes.

Finally, the view from a limited admin when they log in. Please note the group selector in the top-center area.
