A method of authenticating a client comprising receiving (400), at an application server from a client, a connection request and sending (402), from the application server to the client, a request for client authentication identifying at least one repository server and at least one associated authentication method; selecting, at the client, an identified repository server and an associated first authentication method; a selected repository server receiving (404) a first authentication request including a first authentication credential indicated by the selected authentication method from the client. The repository server authenticates the client according to a first authentication method using the first authentication credential and sends (406) to the client, first authentication information indicating whether the client is authenticated to the repository server, which the client forwards (408) to the application server. The application server may request multiple authentications for the client at different repository servers or using different authentication methods. |
