[Serusers] Restrict registration to one user per login

[Jffdsaklj dsjk]

Finally I found a solution. I've attached the block I included in the
SER cfg file.
The problem (big problem) is that after a day (more or less), there
are defunct processes. I think it's a problem of the exec_msg
sentence, but I'm not sure. With these defunct processes, SER crashed.
:(

    break;
   };

   # This block prevents a user from registering with a login
previously registered from another machine

   # Verify it's not a deregistration message

     # It's a registration message
     # Verify that there's no register in the table location with the
same user but from a differente machine
     if (
          !exec_msg('
               USUARIO=`echo $SIP_HF_FROM | sed -n "s/<sip:\(.*\)@.*/\1/p"`;
               QUERY="select username from location where
username=\"$USUARIO\" and contact not like \"sip:$SIP_SRCIP:%\"";
               RESULT=`mysql -uXXX -pXXX -e "$QUERY" ser`;
               if [ -z "$RESULT" ]; then exit 0; else echo "The user
$USUARIO is already registered" >> /var/log/serprueba.log; exit 1;
fi;')
     ) {
       # The user is already registered
       sl_send_reply("404", "Not Found");
       break;
     };
   }

   save("location");
   break;
  };
