#save(nsc) ⇒ Boolean

end

#test(nsc, target, engine_id = nil) ⇒ Object

Test this credential against a target where the credentials should apply. Only works for a newly created credential. Loading an existing credential will likely fail.

Parameters:

  • nsc (Connection) —

    An active connection to the security console.

  • target (String) —

    Target host to check credentials against.

  • engine_id (Fixnum) (defaults to: nil) —

    ID of the engine to use for testing credentials. Will default to the local engine if none is provided.
