23.6 Tunneling from DCC to Access Manager Over Oracle Access Protocol

Access Manager supports HTTP communication over the Oracle Access Protocol (OAP). In this case, a WebGate configured as a DCC uses the ECC servlets for credential collection during Access Manager authentication.

The following sections contain more details.

23.6.1 How DCC Tunneling with OAP Works

The tunneling process works for DCC WebGates only.

Figure 23-5 illustrates how the tunneling process works.

The following steps provide more details in regards to the OAP Tunneling process.

  1. The URL to be tunneled is configured in the DCC WebGate profile.

  2. This same URL is mapped to a servlet or JSP page in the Access Manager server.

  3. On accessing the tunneled URL, the WebGate intercepts the HTTP request and converts it to an OAP request.

  4. The OAP request is forwarded to the Access Manager server.

  5. The Access Manager server (OAM proxy) receives the OAP request and passes it to the tunnel proxy.

  6. The tunnel proxy will convert the OAP request to an HTTPServletRequest and invoke the corresponding servlet (or compiled servlet in the case of a JSP).

  7. The response is converted back to an OAP message and passed to the OAP end point.

  8. The OAM end point responds to the WebGate with the converted OAP message.

  9. The WebGate converts the OAP message back to an HTTP response.

  10. The WebGate provides the HTTP response to the caller (browser).

23.6.2 Configuring OAP Tunneling

To configure OAP Tunneling, a WebGate must be installed and configured to work with the Access Manager server as a DCC.

The Access Manager endpoint must be deployed on the Access Manager Server. After ensuring these prerequisites have been met, add a user-defined parameter to the WebGate profile that defines all URLs to be tunneled using the form TunneledUrls=<URL>,<URL1>. For example:


Lastly, protect the Tunneled URLs with an Authentication Policy. For details, see Managing Authentication and Shared Policy Components.
