Fwd: unmatch Acctsessionid is stored on mysql database

[khalil at awrosoft.com]

Dears,

i have installed freeradius and i'm using mysql as a data store, but i have a problem and the problem is,  user is connecting successfully but with a different acctsessionid, for example NAS send acctsessionid= 000003A9 for user alice but 00000396 will be saved on the database. 
does anyone knows what is the problem why acctsessionid is changed. 

any help will be appreciated,
thanks,
Khalil
