Mikrotik as NAS with PPPoE - checkval

[Maciej Drobniuch]

Hi!
I want to bind a login with Calling-Station-Id but i've got problems...
*I've had added the Calling-Station-Id to mysql radcheck table.
*I've had turned on the rlm_checkval by adding it into authorize section
*I've had set the notfound-reject variable to yes

I get the following errors in debug:
rlm_checkval: Item Name: Calling-Station-Id, Value: 00:11:22:33:44:55
rlm_checkval: Could not find attribute named Calling-Station-Id in check
pairs
++[checkval] returns notfound

What is the problem? 
Please help!
Thanks for all!!!
