From 3899f95e1f44a4dfe31b42119ad5e14304d8a4b4 Mon Sep 17 00:00:00 2001 From: Volker Lendecke Date: Fri, 7 Jul 2006 18:53:19 +0000 Subject: r16865: This is a proposal to fix bug 3915. Before sending patches around, this is what svn is for. The idea is that we fall back to a pure unix user with S-1-22 SIDs in the token in case anything weird is going on with the 'force user'.
