Interface AuthProvider

All Known Implementing Classes:

ClearspaceAuthProvider, CrowdAuthProvider, DefaultAuthProvider, HybridAuthProvider, JDBCAuthProvider, LdapAuthProvider, NativeAuthProvider, POP3AuthProvider

public interface AuthProvider

Provider interface for authentication. Users that wish to integrate with their own authentication system must implement this class and then register the implementation with Openfire in the openfire.xml file. An entry in that file would look like the following:

   <provider>
     <auth>
       <className>com.foo.auth.CustomAuthProvider</className>
     </auth>
   </provider>

Method Detail

isPlainSupported

boolean isPlainSupported()

Returns true if this AuthProvider supports authentication using plain-text passwords according to JEP--0078. Plain text authentication is not secure and should generally only be used for a TLS/SSL connection.

Returns:

true if plain text password authentication is supported by this AuthProvider.

isDigestSupported

boolean isDigestSupported()

Returns true if this AuthProvider supports digest authentication according to JEP-0078.

Returns:

true if digest authentication is supported by this AuthProvider.

                         InternalUnauthenticatedException

Returns if the username and password are valid; otherwise this method throws an UnauthorizedException.

If isPlainSupported() returns false, this method should throw an UnsupportedOperationException.

Parameters:

username - the username or full JID.

Returns if the username, token, and digest are valid; otherwise this method throws an UnauthorizedException.

If isDigestSupported() returns false, this method should throw an UnsupportedOperationException.

Parameters:

username - the username or full JID.
