[this is my first PR for FreeBSD, so please bear with me if I missed something]

I've set up a FreeRadius server on this amd64 machine wich is running just fine using flat files ("users") to do the authorization. Now I wanted to switch to a mysql backend (I've chosen "ldap" and "mysql" when I did "make" in the portsdir). 
Radiusd starts just fine:

Info: rlm_eap_tls: Loading the certificate file as a chain
Info: rlm_sql (sql): Driver rlm_sql_mysql (module rlm_sql_mysql) loaded and linked
Info: rlm_sql (sql): Attempting to connect to root at localhost:/conusrdb
Info: rlm_sql_mysql: Starting connect to MySQL server for #0
Info: rlm_sql_mysql: Starting connect to MySQL server for #1
Info: rlm_sql_mysql: Starting connect to MySQL server for #2
Info: rlm_sql_mysql: Starting connect to MySQL server for #3
Info: rlm_sql_mysql: Starting connect to MySQL server for #4
Info: Ready to process requests.

But when it receives an auth-request id dies with:

kernel: pid 48382 (radiusd), uid 30323: exited on signal 10

(that's why I've chosen "kern" for "Category" of this PR)


>How-To-Repeat:
enable "sql" in radiusd.conf:

authorize {
   ...
   sql
}

Have the NAS (Network Access Server, in my case a Netgear Wireless AP) send an Auth-Request to the AAA (radius server) and watch it die with:

kernel: pid 48382 (radiusd), uid 30323: exited on signal 10
