Cannot remove 'Library Administrator' group from having Full Control on Spotfire Library
By default, "Library Administration" group is not visible under the "Permissions for Selected Folder" section of the root Library folder (Analyst Client >> Tools >> Library Administration. If the root folder is edited by using the 'Edit' option without selecting any of the library folders and if the "Library Administration" group is added to "Full Control" section of the permissions, it can never be removed from this permissions list.
The 'Library Administrator' group by default has -
1)Complete access to the Library
2)Is invisible when you look at the Root Folder Permissions
3)Members of this group are also the only ones allowed to create, delete and change permissions for top level folders.
4)Additional groups can also be provided access to the Library Administration via the Group Licenses but they will be unable to edit permissions on the Library folders unless they have been granted explicit access to the required folder whereas a user who is a member of the Library Administration can edit any of the available library folders.
Once changes are made to the 'Root/Library' permissions, then this group will be visible and it can't be removed as Spotfire needs to have a default group with Full Control on the Library.
