From e07913c2c5e4dc5e406c2cb12cf78150cab3d95a Mon Sep 17 00:00:00 2001 From: Steve Dickson Date: Sat, 17 Nov 2012 08:50:09 -0500 Subject: svcgssd: Encryption types not being parsed correctly When svcgssd reads the supported encrytion types from the kernel, they are prefixed with a 'enctypes='. That prefix has to be ignored to correctly parse the rest of the types.
