> sasl-authentication-factory and sasl-server-factory creates chain of SaslServerFactories - for example ServerNameSaslServerFactory only delegates creating to following with rewriting of the server name.
> In this chain is also *SetMechanismInformationSaslServerFactory*, which only call callback handler to send MechanismInformation into ServerAuthenticationContext - there it will cause state change from InactiveState to InitialState.
> The problem is, if the configurable-sasl-server-factory is used, the *SetMechanismInformationSaslServerFactory* is in chain twice. The first occurence (by sasl-authentication-factory) will cause change state to InitialState, but before the serverName+protocol is overriden by SaslServerFactories following in chain. The second occurence (by configurable-sasl-server-factory) already have serverName+protocol set, but because the ServerAuthenticationContext is already in InitialState, the exception "Too late to set" is thrown and createSaslServer returns null - fail completely.
> The chain of SaslServerFactories:
> {code:java}
> AuthenticationTimeoutSSF
> TrustManagerSSF
> AuthenticationCompleteSSF
> SetMechanismInformationSSF => cbh => InactiveState -> InitialState(undefined, null)
> ServerNameSSF
> ProtocolSSF
> SetMechanismInformationSSF => cbh => "Too late to set" => return null
> SecurityProviderSSF
> {code}
