Managing External Applications

15 Managing External Applications

An external application is any application that implements its own authentication process. Specifically, it is an application that does not take part in the single sign-on process for WebCenter Portal.

Application administrators can register and manage external applications using Fusion Middleware Control or the WLST command-line tool, or at runtime through built-in administration pages or using external application task flows.

All external application changes that you make for WebCenter Portal post deployment, are stored in the MDS repository as customizations.

Note:

External application configuration is dynamic. Configuration changes are immediately reflected in WebCenter Portal; it is not necessary to restart the application or the managed server.

Permissions:

To perform the tasks in this chapter, you must be granted the WebLogic Server Admin role through the Oracle WebLogic Server Administration Console and the Administrator role granted through WebCenter Portal Administration.

For more information about roles and permissions, see Understanding Administrative Operations, Roles, and Tools.

15.1 About External Applications

If WebCenter Portal interacts with an application that handles its own authentication, you can associate that application with an external application definition to allow for credential provisioning. In doing so, you use an external application definition to provide a means of accessing content from these independently authenticated applications.

To replicate a single sign-on experience from the end user's perspective, the external application service captures the user name and password, and any other credentials for the external application, and supplies it to the WebCenter Portal tool or application requiring the credentials. The WebCenter Portal tool or other application then uses this information to log in on behalf of the end user. This username and password combination is securely stored in a credential store configured for the WebLogic domain where the application is deployed.

Note:

When logging in to an external application, if you clear the Remember My Login Information check box, then the credentials provisioned for that user session are lost in the event of a failover in a high availability (HA) environment. You are prompted to specify the credentials again if you try to access the external application content in the same user session.

15.2 Registering External Applications

You can register external applications for WebCenter Portal through Fusion Middleware Control or using WLST commands.

Before registering an external application, access the application's login page and examine the HTML source for the application's login form. All the registration details you require are located in the <form tag>.

For example, the underlying code for the Yahoo! Mail login form looks something like this:

<form method=post action="https://login.yahoo.com/config/login?" autocomplete="off" name="login_form">
...
<td><input name="login" size="17"</td>
...
<td><input name="passwd" size="17"</td>
...

In this example, to provide WebCenter Portal users with a direct link to the Yahoo! Mail application, the following sample registration information is required:

Registration Information	Sample Value	HTML Source
Login URL	`https://login.yahoo.com/config/login?`	`action`
User Name / User ID Field	`login`	`name="login`"
Password Field Name:	`passwd`	`name="passwd"`
Authentication Method	`post`	`method`

Note:

External application configuration is dynamic. New external applications and updates to existing applications are immediately available; there is no need to restart WebCenter Portal.

This section includes the steps for:

Table 15-2 External Application Connection - Login Details

Field	Description
Enable Automatic Login	Select to allow automatically log users in to this application. Choosing this option requires you to complete the Login URL, HTML User ID Field Name, and HTML User Password Field Name fields With automated single sign-on, the user directly links to the application and is authenticated automatically, as their credentials are retrieved from the credential store. Selecting this option provides the end user with a seamless single sign-on experience. Note: Automated login is not supported for: External applications using BASIC authentication. External applications configured for SSO. External applications with a customized login form (built using ADF Faces) that does not implement the J2EE security container login method j_security_check for authentication. External sites that do not support UTF8 encoding. External applications that accept randomly generated hidden field values or cookies for successful login.
Login URL	Enter the login URL for the external application. To determine the URL, navigate to the application's login page and record the URL. For example: `http://login.yahoo.com/config/login` Note: A login URL is not required if the sole purpose of this external application is to store and supply user credentials on behalf of another service.
HTML User ID Field Name	Enter the name that identifies the "user name" or "user ID" field on the login form. Tip: To find this name, look at the HTML source for the login page. This property does not specify user credentials. Mandatory if the Authentication Method is GET or POST. Leave this field blank if the application uses BASIC authentication (see Authentication Method).
HTML User Password Field Name	Enter the name that identifies the "password" field on the login form. Tip: To find this name, look at the HTML source for the login page. Mandatory if the Authentication Method is GET or POST. Leave this field blank if the application uses BASIC authentication (see Authentication Method).

Select the authentication method used by the external application.

Table 15-3 External Application Connection - Authentication Details

Field Description

Field	Description
Authentication Method	Select the form submission method used by the external application. Choose from one of the following: GET: Presents a page request to a server, submitting the login credentials as part of the login URL. This authentication method may pose a security risk because the user name and password are exposed in the URL. POST: Submits login credentials within the body of the form. This is the default. BASIC: Submits login credentials to the server as an authentication header in the request. This authentication method may pose a security risk because the credentials can be intercepted easily and this scheme also provides no protection for the information passed back from the server. The assumption is that the connection between the client and server computers is secure and can be trusted. The Authentication Method specifies how message data is sent by the browser. You can find this value by viewing the HTML source for the external application's login form, for example, `<form method="POST" action="https://login.yahoo.com/config/login?" AutoComplete="off">`

15.5 Managing External Applications at Runtime

An external application is any application that implements its own authentication process. Specifically, it is an application that does not take part in the WebCenter Portal application's single sign-on process. If your WebCenter Portal application interacts with an application that handles its own authentication, you can register an external application to allow for credential provisioning.

By default, users with the Administrator role have the AppConnectionManager role; and therefore, can configure and manage external applications through the WebCenter Portal Administration Console at runtime. For more information about AppConnectionManager role, see Default Application Roles.

This section includes the following topics:

15.5.1 Registering External Applications at Runtime
