Abstract: User authentication is based on a home network user database that authenticates users to external service providers. A user logs into home network and starts accessing the external service by clicking on a link labelled for the external service provider. The link is directed to script at a home server. The script causes the home server to obtain details related to the user from a home network user database. The home server passes information related to the user to a foreign server associated with the service provider. Based on the passed information, the foreign server grants or denies authentication of the user to the external service. If granting, the foreign server provides the home server with access data and the home server forwards the access data to the user so that the user can initialize an authorized external service session using the access data.

Abstract: A method is described for providing access to service in an access management system accessible via a data network, in which data network a user is registered and/or authenticated to a service by providing at least one detail related to the user. A user is provided with an option to add a direct view to the service from an external micro application platform and allowed to select the option of adding the direct view and responsively negotiating with the external micro application platform credential information in order to form a trusted relationship for accessing the direct view from the external micro application platform. After recognizing of a show view request from the external micro application platform based on the trusted relationship, the external micro application platform is provided with the view to the service. Corresponding method in a micro platform is described.
