[RADIATOR] Slow Auth process

Hello,

Trying to implement a MFA with offband token validation.

The validation phase, between receiving a SMS, opening the web page  
and clicking the validation link, can take from a couple of seconds to  
30s where the radius auth process is waiting to either ACCEPT or REJECT.

So, the solutions to allow for other authentications to happen at the  
same time are:

1. we set a FarmSize other than 0, but we break the use of Context and  
so multiple auth methods stop working, or

2. we Fork the authentication process where the validation happens  
(AuthBy SMSToken)

The last seems to be the best solution but we can't seem to get it  
working properly. On IGNORE the authentication continues and the  
clients end up getting an ACCEPT. The SMSToken continues on the  
background but to no use.

The configuration is:

<Handler ...>

    AuthByPolicy ContinueUntilReject

    <AuthBy GROUP>

        AuthByPolicy ContinueUntilAccept

        AuthBy NTLM_DOM_A

        AuthBy NTLM_DOM_B

        AuthBy NTLM_DOM_C

    </AuthBy>

    AuthBy SMSToken

    AuthBy DynPool_this

</Handler>

Thank you.
