[OpenSIPS-Users] How to limit number of AOR for user

[Răzvan Crainea]

Can you print $avp(maxaor) just before the save() function? I am pretty 
sure it is not populated. And the reason is that you are not specifying 
an AVP to store it. The load_credentials parameter should be
"$avp(loadedip)=domain;$avp(subscriber_username)=username;$avp(maxaor)=maxaor"
