Abstract: A distributed session failover mechanism is disclosed for facilitating the replication and retrieval of session information. A first server, in a trusted network, providing a single sign-on (SSO) solution, stores session information pertaining to a particular client requesting services associated with the server. In order to provide session failover, the first server sends a copy of the session information to a bus mechanism, which is connected to one or more persistent repositories. When a second server attempts to validate the client, the second server may discover that the first server failed. The second server then requests a copy of the session information pertaining to the client from the bus mechanism. The bus mechanism retrieves the copy from a persistent repository and provides the copy to the second server.

Abstract: A method to limit active sessions connecting user access to a computer network is presented. First, a request to initiate a new user session in the computer network is authenticated. The authentication is operatively conducted within a single sign-on provider. A session quota is then determined through a session quota logic of the single sign-on provider with the session quota logic retrieving a stored session quota. Then the number of active sessions is compared with the determined session quota. The determined session quota is enforced though a session quota enforcement logic of the SSO provider.
