getPrincipal

public java.security.Principal getPrincipal(java.lang.String username)

Description copied from interface: UserRealm

Get the principal for a username. This method is not guaranteed to return a Principal for non-authenticated users.

Specified by:

getPrincipal in interface UserRealm

isUserInRole

public boolean isUserInRole(java.security.Principal user,
                            java.lang.String role)

role - A role name.

Returns:

True if the user can act in that role.

reauthenticate

public boolean reauthenticate(java.security.Principal user)

Description copied from interface: UserRealm

Re Authenticate a Principal. Authenicate a principal that has previously been return from the authenticate method. Implementations of this method may adorn the calling context to assoicate it with the authenticated principal (eg ThreadLocals). If such context associations are made, they should be considered valid until a UserRealm.deAuthenticate(UserPrincipal) call is made for this UserPrincipal.

Specified by:

reauthenticate in interface UserRealm

Returns:

True if this user is still authenticated.

authenticate

public java.security.Principal authenticate(java.lang.String username,
                                            java.lang.Object credentials,
                                            Request request)

Authenticate a user.

Specified by:

public void disassociate(java.security.Principal user)

Removes any auth info associated with eg. the thread.

Specified by:

disassociate in interface UserRealm

Parameters:

user - a UserPrincipal to disassociate

pushRole

public java.security.Principal pushRole(java.security.Principal user,
                                        java.lang.String role)

Temporarily adds a role to a user. Temporarily granting a role pushes the role onto a stack of temporary roles. Temporary roles must therefore be removed in order.

Specified by:

pushRole in interface UserRealm

Parameters:

user - the Principal to which to add the role

role - the role name

Returns:

the Principal with the role added

popRole

public java.security.Principal popRole(java.security.Principal user)

Description copied from interface: UserRealm

Parameters:

user - A UserPrincipal previously returned from pushRole

Returns:

The principal without the role. Most often this will be the original UserPrincipal passed.

getRoles

public java.security.acl.Group getRoles(JAASUserPrincipal principal)

logout

public void logout(java.security.Principal user)

Logout a previously logged in user. This can only work for FORM authentication as BasicAuthentication is stateless. The user's LoginContext logout() method is called.

Specified by:

logout in interface UserRealm

Parameters:

user - an Principal value
