Method Detail

disconnectClient

public void disconnectClient(String clientIdentifier)

Description copied from interface: IAuthenticationManager

Called to notify the authentication system that the client has disconnected. Each implementation will decide what to do in this case. Either do nothing and keep the user connected (if the authentication repository is shared by external systems), of logout the user from the authentication system (if it is a DIF specific authentication system).

Specified by:

disconnectClient in interface IAuthenticationManager

Parameters:

clientIdentifier - the Id that identifies the specific client. Depends on the Channel used to communicate

See Also:

IAuthenticationManager.disconnectClient(java.lang.String)

getLoggedUser

public IDIFUser getLoggedUser(String clientIdentifier)
                       throws AuthenticationManagerException

Description copied from interface: IAuthenticationManager

Searches for the user authenticated for this client in the authentication system and returns it if present.

Specified by:

getLoggedUser in interface IAuthenticationManager

Parameters:

clientIdentifier - the Id that identifies the specific client. Depends on the Channel used to communicate

Returns:

the authenticated user record

Throws:

AuthenticationManagerException - if the resources needed for authentication can't be accessed

See Also:

IAuthenticationManager.getLoggedUser(java.lang.String)

isClientLogged

public boolean isClientLogged(String clientIdentifier)

Description copied from interface: IAuthenticationManager

Checks if a given user is already authenticated on the Authentication Module. TODO: When integrating External Authentication/Authorization/Identity servers like LDAP, Kerberos and others this may change a bit. See these APIs for good candidates for implementing these needs: http://www.ja-sig.org/products/cas/index.html http://www.acegisecurity.org/

Specified by:

isClientLogged in interface IAuthenticationManager

Parameters:

clientIdentifier - the Id that identifies the specific client. Depends on the Channel used to communicate
