[Satosa-dev] hasher microservice

Hi- After upgrading our Satosa to the latest, I am getting some deprecation warnings in the Satosa log. I'll address the other 2 warnings later (I think they are related to python3), but for now I'm interested in how to use the new hasher microservice. I am not having much luck finding documentation for it. The warning in the log is this: "/usr/local/lib/python3.6/site-packages/satosa/base.py:56: DeprecationWarning: 'USER_ID_HASH_SALT' configuration option is deprecated. Use the hasher microservice instead." Can you point me to some help in using that new microservice? Thanks!
