public class InvalidPrincipalException
extends java.lang.SecurityException
InvalidPrincipalException
exception is thrown by a security
provider if the principal that was generated for a user has become invalid.
For example, the InvalidPrincipalException
may be thrown because
the principal has been deleted from the system while there was
an active subject with that principal, or if there is a principal that purports to be
in a given security realm but it is not in that realm.
