Authentication us mySQL and AD(LDAP)

[chenjiang]

   Hi! Experts

   Sorry for disturbing, I am struggleing with FreeRADIUS user
   authentication through Windows AD(LDAP), but I found when enable LDAP
   mySQL backend is not works any more.

   From debug output(radius -X), we found even mySQL module returns
   OK,FreeRADIUS still returns Accept-Reject when LDAP module returns
   fail.

   Waking up in 4.9 seconds.

   Cleaning up request 0 ID 130 with timestamp +25

   Ready to process requests.

   Is this expected behaviour? How can I enable them() both at same time,
   The scanario is I want to use AD for internal exploymee 802.1x
   authentication and use mySQL for visitor authentication.

   Thanks for your support!
   BR!
