Microsoft SQL connector for logins

I’m just attempting this and not sure if it’s even supported on RC. Authenticating from a MS SQL Server.

We have a licensed Microsoft Sql Server. One of our web servers integrated with it to authenticate username and password logins.

Its integrated with:
Database Host:
Database Name
Database user/password
Database Table: Web_users
username field: username
password field: user_password

I notice the Zapier app for Sql, but we can’t afford it for the number of requests taking place each month.

I have no idea where to start on this integration for login…

Just a nudge in right direction would be helpful.

Thank you!
