Problem with Alcatel 4604 and Cisco ACS

[matteo]

   Hello,
I'm in trouble trying to authenticate a client connecting to an Alcatel 
4604 (Aruba device) to a Cisco ACS, because my alcatel send as 
Called-Station-Id value its mac-address. On the Cisco side, this value 
correspond to the SSID value, while this attribute on Alcatel is send 
via Aruba-Essid-Name (attribute 5 in dictionary.aruba). Is there a way 
to change this behavior or a remap of this attribute for Alcatel?
Thanks.
Matteo
