Authentication protocol support

Use this page to reference information regarding supported authentication protocols.

Authentication protocol support

Beginning with WebSphere® Application Server Version 7.0, the WebSphere Application Server Version 7.0 servers only support the Common Secure Interoperability Version 2 (CSIv2) authentication protocol. Secure Authentication Service (SAS) is only supported between Version 6.0.x and previous version servers that have been federated in a Version 7.0 cell. The option to select between SAS, CSIv2, or both will only be made available in the administration console when a Version 6.0.x or previous release has been federated in a Version 7.0 cell.

In future releases, IBM® will no longer ship or support the Secure Authentication Service (SAS) IIOP security protocol. It is recommended that you use the Common Secure Interoperability version 2 (CSIv2) protocol.

You can configure both protocols to work simultaneously between Version 6.0.x and previous version servers that have been federated in a Version 7.0 cell. If a server supports both protocols, it exports an interoperable object reference (IOR) that contains tagged components describing the configuration for SAS and CSIv2. If a client supports both protocols, it reads tagged components for both CSIv2 and SAS. If the client and server support both protocols, CSIv2 is used. However, if the server supports SAS (for example, the server is a previous WebSphere Application Server release) and the client supports both protocols, the client chooses SAS for this request.

Choose a protocol using the com.ibm.CSI.protocol property on the client side and configure this protocol through the administrative console on the server side.
