WARNING: Outer and inner identities are the same. User privacy is compromised.

I have a clean Freeradius install v. 3.0.14, and  so far just made a few 
config modifications and generated new certificates.  My test user is 
added to users (.../raddb/users).

My task is to set up WPA enterprise.  I'm testing with my iPhone, and it 
seems to work fine.  But in the 'log' (radiusd -X output) the following 
message appears:

(35) Virtual server inner-tunnel received request
(35)   EAP-Message = 0x027000061a03
(35)   FreeRADIUS-Proxied-To = 127.0.0.1

(35)   State = 0x9197e30a90e7f90d1e18c9ac6236626c
(35) WARNING: Outer and inner identities are the same.  User privacy is

/usr/local/etc/raddb/sites-enabled/inner-tunnel

This seems kind of bad, any ideas?
