Sample Sql Authentication Provider implementation

This repository provides a sample implementation of SqlAuthenticationProvider that can be used for ActiveDirectoryInteractive authentication mode with System.Data.SqlClient as well as Microsoft.Data.SqlClient (with namespace toggle).

The CustomAuthProvider implements SqlAuthenticationProvider and the authentication is performed using MSAL (Microsoft.Identity.Client).

  • DataSource: Target Azure SQL Server endpoint
  • InitialCatalog: Name of Azure Database instance
  • UserID: Username for silent authentication (applicable when cache is persisted)
