Windows RDP SMS doesn't work

[rmoreRojoli]

Hi, I have moved a 5.8.2.9 server running in docker to 5.9.7.1, uninstalled the old Credential Provider on Windows and installed the new 5.9.7.1 version. On the server when I test a user like multiotp USERNAME sms I receive the SMS and I see the debug logs as well working. However when I try to log in through RDP on the Windows side it says SMS sent but in the logs I get the following:

debug CredentialProviderRequest Info: Value for IsCredentialProviderRequest: 0 364801b3491b debug Server-Client Info: CheckUserExists server request for USERNAME with challenge XXX 0 364801b3491b debug Server-Client Info: CheckUserExists intermediate error code: 22 0 364801b3491b debug Server-Client Info: Server secret used for command CheckUserExists with error code result 22: b3b8af57b6b247b5 0 364801b3491b debug CredentialProviderRequest Info: Value for IsCredentialProviderRequest: 0 364801b3491b debug Server-Client Info: ReadUserData server request for USERNAME 0 364801b3491b debug Server-Client Info: *Server secret used for command ReadUserData with error code result 19: b3b8af57b6b247b5 0 364801b3491b

I have installed the Cred Provider with https://IP:8443 and server secret, no cache, allow SMS on login screen, remote only option

Is there something I left out or changed in the config? Thanks for the help!

Hello, it looks like your secret is not the same on the server and on the Credential provider. In docker can you please run the following command : php multiotp.php -config server-secret=abcd1234 (try with abcd1234, juste to make sure there is no special caracters that are not supported)

Then on the Windows RDS go to the registry and change the value of : HKEY_CLASSES_ROOT\CLSID{FCEFDFAB-B0A1-4C4D-8B2B-4FF4E0A3D978}\multiOTPSharedSecret to abcd1234

Try to login

If it works change the secret to something more complex.

Issue seems to persist even with that change and a reboot:

Do you click on the button "Receive an OTP by SMS" ? Did you configure the SMS provider settings ? (sms-password, sms-userkey, sms-provider)

What is you sms provider ?

Best regards

[rmoreRojoli]

These logs are generated when I click "Receive an OTP by SMS" Using the custom SMS provider I have Twilio set up, which works with the multiotp USERNAME sms command

[multiOTP]

Is it the case for all users ?

[multiOTP]

Hello, can you please delete all the files in [ProgramFiles]\multiOTP\users and try again.

If it's still not working can you please check if the user.db file is created in this folder

Best regards
