WPA2 Enterprise and RADIUS

I configured my Aironet 1262N autonomous AP to authenticate and account my users against a FreeRADIUS server. In the RADIUS server database, I saw some records like:

select username, acctauthentic, acctterminatecause, acctstarttime, acctstoptime from radacct where username='xxxxxx';

As you can see, the Acct-Authentic fields contains two possible values: Local and RADIUS. I didn't create any user with name 'xxxxxx' on AP, and I configure the authentication is against the RADIUS server. Why there are so many Acct-Authentic = 'Local'?

Also, this user always lost his connection and then reconnected quickly. This user login his account in multiple devices, including smart phone and computers. All of them are experiencing the same issue. Is there anyway to debug it? Any protential reasons?
