Lookup the TlsSRPLoginParameters corresponding to the specified identity. NOTE: To avoid "identity probing", unknown identities SHOULD be handled as recommended in RFC 5054 2.5.1.3. SimulatedTlsSRPIdentityManager is provided for this purpose. 
Params:
  • identity – 
           the SRP identity sent by the connecting client
Returns:the TlsSRPLoginParameters for the specified identity, or else 'simulated' parameters if the identity is not recognized. A null value is also allowed, but not recommended.
