<P>
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.
