Freeradius MSSQL

Hi, I'm trying to get Freeradius to work with MSSQL. I have "driver = "rlm_sql_mssql"" but as stated in the above section:

# Configuration for the SQL module # # The database schemas and queries are located in subdirectories: # # sql/<DB>/main/schema.sql Schema # sql/<DB>/main/queries.conf Authorisation and Accounting queries # # Where "DB" is mysql, mssql, oracle, or postgresql.

There should be a file within, sql/mssql/main/schema.sql but it's not there, there is no mssql folder. Also when selecting the rlm_sql_mssql driver, what should be the "dialect"? Should it just be mssql? Thank you!
