Abstract

A technique to establish a secure session to a network-accessible application from a mobile device executing a native app. Initially, the network-accessible application is provisioned for access by an enterprise associating a set of one or more of its enterprise users with the network-accessible application. Thereafter, access to the application is enabled via an identity provider. In operation, the identity provider receives a request to validate that an enterprise user seeking access to the network-accessible application is associated with the application. The request is generated by the application in response to a login request initiated from the native app from a mobile device, wherein a certificate for the application is not available to the native app. Upon validating that the enterprise user is associated with the network-accessible application, the identity provider returns to the application an authentication token evidencing that the enterprise user is permitted to access the network-accessible application for a session.

Claims

1. A method to establish a secure session to a network-accessible application from a mobile device executing a native app, comprising:

configuring the network-accessible application for access by mobile device users by associating a set of one or more enterprise users with the network-accessible application;

receiving a request to validate that an enterprise user seeking access to the network-accessible application is associated with the network-accessible application, the request to validate having been generated by the network-accessible application in response to a login request initiated from the native app to the network-accessible application from a mobile device of the enterprise user, wherein a certificate for the network-accessible application is not available to the native app executing on the mobile device; and

upon validating that the enterprise user is associated with the network-accessible application, returning to the network-accessible application an authentication token, the authentication token evidencing that the enterprise user is permitted to access the network-accessible application for a session;

wherein upon receipt of the authentication token, access to the network-accessible application from the native app executing on the mobile device is enabled for the session.

2. The method as described in claim 1, further including serving a login page to the native app to facilitate establishing the secure session to the network-accessible application from the mobile device executing the native app.

3. The method as described in claim 2, wherein the login page comprises a unique session key, the unique session key comprising an authentication service URL, an update service URL, and a polling service URL.

4. The method as described in claim 3 wherein during an attempt to establish the session, a polling service reachable at the polling service URL receives one or more polls from the login page executing in the native app, wherein a poll seeks an authentication status.

5. The method as described in claim 3 wherein during an attempt to establish the session, an authentication service reachable at the authentication service URL receives and responds to a request to authenticate the unique session key.

6. The method as described in claim 5 wherein during an attempt to establish the session, an update service reachable at the update service URL responds to a successful authentication of the unique session key to generate and provide the authentication token to the network-accessible server.

7. The method as described in claim 1 wherein the authentication token is a SAML assertion.

8. An apparatus configured as an identity provider (IdP) to facilitate establishment of a secure session to a network-accessible application from a mobile device executing a native app, comprising:

a processor;
