Radius authentication passphrase length
-
OK, I got it all cleaned up and patched it. It is yielding the same error from the debug info. From the debug output it looks liek it's grabbing 16 characters.
"username is blahblah with len 8 encryptedpassword is …........with len 16 ........"
-
Any debug from the Encrypt() function? I tested it with 15-17 character passwords and it seemed to do the right thing there. I don't have a way to test against RADIUS, but the function looks good now :-/

No real debug info from the Encrypt() function. I can dig a little deeper. I can also give you access to the box if you'd like.

So it does allow for shorter paswords but generates some errors:
radius-port: 1812 radius-host: 10.10.102.2 username: blahblah key: TestRadiusKey password: testpasswd username is blahblah with len 8 encryptedpassword is šJ»[à6%¤2ÍǃhÄ with len 10 nasHostname is portal-a.lab.local with len 18 writing 95 bytes Warning: Cannot modify header information - headers already sent by (output started at /usr/local/captiveportal/radius_authentication.inc:48) in /usr/local/captiveportal/index.php on line 335 radius-port: 1813 radius-host: 10.10.2.25 username: blahblah username is blahblah with len 8 nasHostname is portal-a.lab.local with len 18 writing 113 bytes [/code] The errors on the RADIUS server for a >16 char passphrase are as i'd expect for an incorrect passphrase. -

It'd be helpful to be able to point at a radius server with an account that has a 17 (or larger) character password. I've got no way of testing that I'm following the RFC correctly - 16 and under still work with the new code I assume?

It authenticates with the new code with a RADIUS box with >=16 passwords but the redirection after fails with some php errors. I assume that is a cosmetic fix and not critical. I can work on getting a radius box up probably tomorrow if that'd be helpful.

So it now authenticates accounts with > 16 char passwords? And authenticates accounts with < 16 char passwords? Only a PHP error to cleanup? Good news. Maybe the PHP error is coming from the $debug define.

Actually it only authenticates 16 char or below passwords. I mistyped. Sorry.

Has anyone else noticed this behavior? Would it be beneficial for me to set up a RADIUS box and give you access to test against?

Yes, please do. Bill does not have access to a tesitng environment for this.

If you can provide me a radius target I can test this myself.

I'll work on this this afternoon and post when it's done.

I have this up, I'm still verifying correct functionality. How would you like to go about testing?
-
ok, I have this working whenever you'd like to start working on it.

Can you PM me an IP to test against along with two usernames, one with a 15 char password, one with a 20 char password. I can provide a static IP if needed that I'll be testing from.

OK, fixed. Thanks!
Grab http://www.pfsense.org/~billm/radius_authentication.inc.txt until this is commited.

I also verified that the code in HEAD works, it's only RELENG_1 that's affected by this.

This works like a dream now, even in my wacky kerberos backended setup.
Thanks for all the hard work, it is appreciated.nb

So what exactly should I MFC?
