[EdLUG] Lubuntu 14.04 guest session login failure

[Edinburgh Linux Users Group]

Hi,

I don't see how a guest could be causing this issue.  We are experiencing
this guest session login failure loop on several machines at several
difference low income shelters.  We are still stymied.  Someone suggested
that removing appamor would work, but it didn't.
