[Serusers] Problem when Uncomment loadmodule "/usr/local/lib/ser/modules/auth_db.so" digest authentication

[mohammed irfan]

Hello,

we are using ser version 0.8.14 and the script ser.cfg is working fine without database.
But after enabling write to database mode, and digest authentication we get one way request and no response from the server.

We variefied this is happening when we uncomment 
loadmodule "/usr/local/lib/ser/modules/auth_db.so"

I am sending U the complete script which we are using, please help us to solve our problem.
