I did not test it however when I tried stratum proxy for YAC shares were not stored in DB... what worker name did you use?
The best would be to put changes required for YAC/YBC into newest pooler's cpuminer ith stratum support
Finally, it works great, thanks a lot!
Incredible speed!!

The method works, but can not accredits share.
I changed several times the worker's name and password!
