      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?

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

                          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.

                                    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.
