Method Detail

getAuthType

public int getAuthType()

Description copied from interface: ISecurityContext

Returns the canonical authentication type for this flavor of authentication. Each value returned should be either a globally registered auth flavor or a local variant.

Specified by:

getAuthType in interface ISecurityContext

Returns:

The unique authentication value identifier. Values with the high order 16 bits clear are local (0x0000 - 0x00FF) where values with the high order 16 bits set (0xFF00 - 0xFFFF are foundation types distributed by JASIG. All other should be registered and globally unique.

getAdditionalDescriptor

public IAdditionalDescriptor getAdditionalDescriptor()

Description copied from interface: ISecurityContext

Returns any additional descriptor information that might have been acquired during the process of authentication. Note that this interface has no methods and the object returned will have to be cast to some concrete type or alternate interface to be useful.

Specified by:

getAdditionalDescriptor in interface ISecurityContext

Overrides:

getAdditionalDescriptor in class ChainingSecurityContext

Returns:

An object containing any additional descriptor information.

IAdditionalDescriptor

authenticate

public void authenticate()
                  throws PortalSecurityException

Description copied from class: ChainingSecurityContext

We walk the chain of subcontext assigning principals and opaquecredentials from the parent. Note that the contexts themselves should resist actually performing the assignment if an assignment has already been made to either the credentials or the UID.

Specified by:

authenticate in interface ISecurityContext

Overrides:

authenticate in class ChainingSecurityContext

Throws:

PortalSecurityException
