Subject: [PATCH 22/23] oidc_child: increase wait interval by 5s if 'slow_down'
is returned
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
While waiting for the user to authenticate with the IdP oidc_child
currently only handles the error code 'authorization_pending' and waits
for the given interval until a new request is send. But there is also
'slow_down' which should not be treated as fatal error but should just
increase the waiting time permanently for 5s.
