From 34ea46ef8c4d94f59c11a7b1edc79db382970e0c Mon Sep 17 00:00:00 2001 From: Jeremy Allison Date: Tue, 10 May 2005 04:25:11 +0000 Subject: r6696: Another attempt to fix the (unreproducible for me) bug #2346 (read-only excel files). Ensures that any missing user ACL entry will be generated from a union of all group permissions that contain the user. Awaiting feedback from the reporters. Jeremy.
