When you remove a trustee of a Novell file system directory or file, you delete a user’s rights to that directory or file. You must have the Access Control right to remove a trustee.
In a file manager, right-click the Novell file or directory whose trustee you want to remove.
Do one of the following:
GNOME: Click Novell Properties.
KDE: Click Actions > Novell Properties.
Click the Novell Rights tab.
In the Trustees list, select the trustee you want to remove.
Click Remove, then click OK.
