MATE eiciel is a Graphical editor for access control lists (ACLs) and extended attributes (xattr), either as an extension within Caja, or as a standalone utility. It's based on Eiciel by Roger Ferrer (http://rofi.roger-ferrer.org/eiciel/). Source code has been modified to allow mate-eiciel to coexist with the original eiciel. Currently has some code to build with Gtk2 in case you have a Gtk2 MATE Desktop, but it will be removed in a future release.
