W10 / Ikev2 + radius on PFSENSE

@aniodon
Try to change
Default EAP Type to

aniodon

Thanks @Konstanti ,

This does not resolve the issue.

here are my test :

User with Clear password, without google : OK
User with MD5 password, without google : KO
User with Clear password, with google : KO
User with MD5 password, with google : KO

@aniodon

and make sure that the IPSEC client and freeradius use certificates signed by the same CA.

aniodon

thanks,

they were indeed different. I corrected the CA and certificate in radius and restarted IPSEC.

i still get (1) Login incorrect (Failed retrieving values required to evaluate condition) , when i am not in a "No password encryption/no google" setup.

Konstanti

@aniodon

You need to stop the Freeradius service
/Status/services/
From the PF console run freeradius in debug mode
radiusd -X

Then you try to establish a connection and analyze the errors

@Konstanti :

Sorry for the delay, took me a while to connect, get logs and sanitize

Thank you @Konstanti, but, you cannot set password when in google mode :

@aniodon

Miscellaneous configuration and hints:

The configuration for different mobile devices can be found here.

And here is the software for mobile devices.

Please read the limitations to make sure how secure this is.

mOTP will probably not work with EAP, CHAP, MSCHAP. If it does - tell me how :-)

aniodon

@Konstanti : The quote is from the mOTP section. Are mOTP and the One-time-Password from users pannel the same ?
mOTP is disabled in my conf

Do you know if i have an alternative ?
i would not like to use credentials in clear text and i would like to use more elaborate ways of authenticate

thank you

Hi @aniodon

Did you ever get this working? I am trying to achieve something similar and have run into the same problem.

aniodon

@nippertje hello, sorry but no. I concluded this was not possible and Just gave up.

jimp

You can't use that kind of OTP with EAP because using mOTP/GA requires PAP which is unencrypted, while EAP will refuse to work with anything less than complete end-to-end encryption of the credentials.

You would need some other sort of MFA hooked into radius, likely from an external/third party radius server.

Thanks @jimp - I found that out with additional reading, so changed tack and now am using OpenVPN with ESET Secure Authentication, which works well and provides convenient push authentication.
