WebContainerLoginModule (Apache JSPWiki 2.11.2 API)

java.lang.Object
- org.apache.wiki.auth.login.AbstractLoginModule
- - org.apache.wiki.auth.login.WebContainerLoginModule

All Implemented Interfaces:

javax.security.auth.spi.LoginModule
```
public class WebContainerLoginModule
extends AbstractLoginModule
```
Logs in a user by extracting authentication data from an Http servlet session. First, the module tries to extract a Principal object out of the request directly using the servlet requests's getUserPrincipal() method. If one is found, authentication succeeds. If there is no Principal in the request, try calling getRemoteUser(). If the remoteUser exists but the UserDatabase can't find a matching profile, a generic WikiPrincipal is created with this value. If neither userPrincipal nor remoteUser exist in the request, the login fails.

This module must be used with a CallbackHandler that supports the following Callback types:
1. HttpRequestCallback - supplies the Http request object, from which the getRemoteUser and getUserPrincipal are extracted
2. UserDatabaseCallback - supplies the user database for looking up the value of getRemoteUser
After authentication, the Subject will contain the Principal that represents the logged-in user.
