/** The interface <code>javax.resource.spi.security.GenericCredential</code>
* defines a security mechanism independent interface for accessing
* security credential of a resource principal.
*
* <p>The <code>GenericCredential</code> interface provides a Java
* wrapper over an underlying mechanism specific representation of
* a security credential. For example, the <code>GenericCredential</code>
* interface can be used to wrap Kerberos credentials.
*
* <p>The connector architecture does not define any standard format
* and requirements for security mechanism specific credentials. For
* example, a security credential wrapped by a GenericCredential
* interface can have a native representation specific to an operating
* system.
*
* <p>The GenericCredential interface enables a resource adapter to
* extract information about a security credential. The resource adapter
* can then manage EIS sign-on for a resource principal by either:
* <UL>
* <LI>using the credentials in an EIS specific manner if the underlying
* EIS supports the security mechanism type represented by the
* GenericCredential instance, or,
* <LI>using GSS-API if the resource adapter and underlying EIS
* instance support GSS-API.
* </UL>
