[StackOverflow/rust] Cannot connect to mssql using rust/tiberius

### ROOT CAUSE The issue arises from a misconfiguration in the connection string, specifically the use of incorrect authentication parameters. The `tiberius` crate requires explicit specification of authentication mode (`IntegratedSecurity` for Windows auth or `Encrypt` for SSL). Without these parameters, the connection attempt fails due to authentication or encryption mismatches. ### CODE FIX Modify the connection string to include the necessary parameters. Here's the corrected Rust code: ```rust use tiberius::Config; let mut config = Config::new(); config .server("your_server.database.windows.net") .user_id("your_username") .password("your_password") .database("your_database") .authentication("SqlPassword") // Explicitly set authentication mode .encrypt("Enabled"); // Ensure encryption is enabled let mut conn = config.connect().await?; ``` **Explanation:** 1. **Authentication Mode:** Set `authentication` to `SqlPassword` (or `IntegratedSecurity` if using Windows auth). 2. **Encryption:** Enable encryption with `encrypt("Enabled")` to avoid SSL/TLS errors. 3. **Correct Parameters:** Ensure all required parameters (server, username, password, database) are correctly specified. This fix addresses common pitfalls when connecting to Azure SQL Database from Rust, ensuring the driver properly handles authentication and encryption.
