About Radius Server Returned time out problem

[DanivosYoun]

Hi Contributors

I got some problem with Pam_Radius_auth,

I configured, Server(pam_radius_auth) -> Microsoft NPS (With Azure MFA Extension)

Auth flow

Try to login pam_radius_auth sent request code 1-> MS NPS received request -> send to Azure MFA -> MS Authenticator Push -> MS NPS Radius -> Response code 2 -> pam_radius_auth Auth Success,

when user clicked MS Authenticator Push with out delay it works perfect

but when, MS Authenticator Push clicked Permit with few delays (about 3~5s ) & auth failed & retry Auth request (on pam_radius.conf timeout parameter 20)

What does the conf file look like?

The code to parse timeout is pretty simple. There's not a lot which can go wrong here.
