Abstract
It is provided a method performed in a gateway and comprises the steps of: receiving a first client request from the client device, the first client request comprising a first fully qualified domain name, FQDN; transmitting a gateway request to the application server; receiving an application server response from the application server, the application server response indicating a need to provide authentication; generating a second FQDN, based on the first FQDN and an identifier of the client device; generating a client specific shared key based on the second FQDN and a shared key; generating a redirect message comprising the second FQDN, an authentication request, a context identifier and the client specific shared key; transmitting the redirect message to the client device; receiving a second client request from the client device; and generating an authentication response in case the second client request fails to comprise an authentication response.
