Hi,

I have a project where I would like to use FreeRadius/OpenVPN to create users through the API and be able to manage the VLAN and network routes by each individual user.
But I am facing issues adding users both through the UI and the FreeRadius API.
Currently I am focusing on just getting the UI to work, then I will go back and test the API.

This the current state:
OpenSense firmware version is 21.1.4
I have created a client in the UI and this user is correctly updated in /usr/local/etc/raddb/clients.conf
client "FreeRadius_local" {.....}

I have created two users in the UI and I can find the users in the config /conf/config.xml
<freeradius>
...
          <user uuid="01911552-c3d2-43ad-b1ef-d3d1021a4bbf">
            <enabled>1</enabled>
            <username>testuser1</username>

            <sessionlimit_max_session_limit/>
            <servicetype/>
            <linkedAVPair/>
          </user>
...
</freeradius>

But in /usr/local/etc/raddb/users only the first user us created!  :(
root@vpnaccess:/usr/local/etc/raddb # cat users

testuser1  Cleartext-Password := "12345678"
       Framed-IP-Netmask = 172.16.1.1,
       Framed-Protocol = PPP


DEFAULT Framed-Protocol == PPP
        Framed-Protocol = PPP,
        Framed-Compression = Van-Jacobson-TCP-IP

DEFAULT Hint == "CSLIP"
        Framed-Protocol = SLIP,
        Framed-Compression = Van-Jacobson-TCP-IP

DEFAULT Hint == "SLIP"
        Framed-Protocol = SLIP

Running freeradius in debug mode, /usr/local/sbin/radiusd -X and testing with System->Access->Tester

I get this error in the browser:

For some reason the password for the first user is garbled.  :(

I hope you can help with an otherwise great product  :)

The local tester has a known bug introduced with 21.1.4. Do you want to apply a patch or wait for 21.1.5?
March 31, 2021, 12:32:53 PM #2
Let me try the patch....

Awesome the patch worked, but unfortunately I still have issues for my first user. The user is still the same as above.

The tester now gives me this:
The following input errors were detected:

radtest is working

When using debug (radiusd -x), how does it look with radtest?
April 07, 2021, 05:51:08 PM #8
I just tried with password like 45te22mQQQ and this worked fine

 :o duh - the shared secret was wrong on the server  :-[

It is actually in this debug output
(0) WARNING: Unprintable characters in the password.  Double-check the shared secret on the server and the NAS!
::)

Thanks for your help
