Method Details

impersonate

GSSCredential impersonate(GSSName name) throws GSSException

Impersonates a principal. In Kerberos, this can be implemented using the Microsoft S4U2self extension.

A GSSException.NO_CRED will be thrown if the impersonation fails. A GSSException.FAILURE will be thrown if the impersonation method is not available to this credential object.

Parameters:: name - the name of the principal to impersonate
Returns:: a credential for that principal
Throws:: GSSException - containing the following major error codes: GSSException.NO_CRED GSSException.FAILURE
