I suppose that first is inherit_user and the second inherit_user_on_chown only isn't? The first always does the role change to the one of the user that calls the binary (always root) the second make the role change after a CHANGE_OWNER request, this last is the one you should mark in the binary. Check if AUTH permit to do this CHANGE_OWNER request (CHANGE_AUTHED_OWNER under UM) El día 14 de diciembre de 2009 19:26, Javier J.
