Hi,

Thanks - that was just was just what I was looking for, although I assume something like the following would go into /etc/freeradius/sites-enabled/default

authorize
{
...
ntlm_auth
        {
                if (User-Password =~ /^(.+)([0-9]{6})$/) {

                 update request {
                 User-Password = "%{1}"
                 Some-PIN-Attr = "%{2}"
                }
        }
        }
...

Although it complains in the debug (radiusd -XXX) about the following:

Wed Apr 17 12:47:23 2013 : Debug: including configuration file /etc/freeradius/sites-enabled/default
Wed Apr 17 12:47:23 2013 : Error: /etc/freeradius/sites-enabled/default[216]: Too many closing braces

Is there a way I could trim a variable (such as a password variable)

using unlang here: http://freeradius.org/radiusd/man/unlang.html#lbAB
but could not find anything about trimming variables.

Use a regexp:

authorize {
...
if (User-Password =~ /^(.+)([0-9]{6})$/) {

update request {
User-Password = "%{1}"
Some-PIN-Attr = "%{2}"
}
}
...
}

If you mean "trim when expanding" you can't; you must transform the variable into another one, then use that. If you don't want to mangle User-Password, define another attribute in the dictionary, taking note of the correct attribute numbers to use (as defined in the comments)
