From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; The virLoginShellAllowedUser method must not free the 'groups' parameter it is given, as that is owned by the caller. The virLoginShellAllowedUser method should be checking '!*ptr' (ie empty string) rather than '!ptr' (NULL string) since the latter cannot be true. Signed-off-by: Daniel P.
