eap sim authentication for multiple clients

[Iliya Peregoudov]

There is a clear distinction between the two cases.

First case: user record is found in users file:

> rad_recv: Access-Request packet from host 192.168.2.1 port 2048, id=1, length=215
[skipped]
> +- entering group authorize {...}
[skipped]
> [files] users: Matched entry 1510019760806391 at wlan.mnc001.mcc510.3gppnetwork.org at line 1
[skipped]
> +- entering group authenticate {...}
[skipped]
> Sending Access-Challenge of id 1 to 192.168.2.1 port 2048

Second case: user record is not found in users file:

> rad_recv: Access-Request packet from host 192.168.2.1 port 2048, id=2, length=215
[skipped]
> +- entering group authorize {...}
[skipped]
> ++[files] returns noop
[skipped]
> +- entering group authenticate {...}
[skipped]
> Failed to authenticate the user.
[skipped]
> +- entering group REJECT {...}
[skipped]
> Sending Access-Reject of id 2 to 192.168.2.1 port 2048

It seems your users file is broken in some way. You need to fix it.
