Trying not to send outer identity in the Access-Accept message

[Torres López María Isabel]

Dear Sir or Madam.
Currently, we are running Freeradius 3.0.11. It works correctly with our wireless controler, but when we upgrade the firmware of our wireless controlles, the users are not able to stablish sesión anymore.
The problem is that the freeradius is sending two User-Name values in the Access-Accept packet (the inner and the outer identity), and the Wireless controler detects two values and drops the packet. The authentication is correct, but the Wireless controller does not stablish the user sesión.
Besides, as the Freeradius sends both identities, sometimes the accountings shows the outer identity, not the inner one.
¿Is there any way to send only the inner identity in the Access-Accept packet?
