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.

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.

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
