The database connection string contains no secret anymore, and can reside in the appsettings, varying by environment. Say hello to your new connection string: Server=,1433 Database=my-database Authentication=Active Directory Default Look ma, no password! For local development, deploy/migrations etc. For apps running on Azure.Īuthenticate with an Azure AD identity by using password-less and non-interactive mechanisms including Managed Identities, Visual Studio Code, Visual Studio, Azure CLI, etc. For my example, there are two relevant authentication modes, with description from the Microsoft docs:Īuthenticate with an Azure AD identity by using system-assigned or user-assigned managed identity. When an application is connecting to an Azure SQL database using AAD authentication, the database connection string must specify an Authentication keyword. It acquires an access token from AAD, attaches it to the SQL connection, and handles token caching and renewal.
#Sql server connection string format driver
The driver takes care of all the magic happening. Version 3.0.0 was released in June 2021, and it leverages Azure.Identity. is the official and recommended driver for SQL Server. This script creates the contained user and grants read and write permissions to the specific database table: CREATE USER FROM EXTERNAL PROVIDER ĪLTER ROLE db_datareader ADD MEMBER ĪLTER ROLE db_datawriter ADD MEMBER 4. When using User assigned identity, the contained user must have the same name as the managed identity. NB! When using System assigned identity, the contained user must have the same name as the app. This can only be done by entities in the AD group set as AAD admin in step 1.

Passwordless or not, you need a user in the database.Įnable authentication to the database by creating a contained user. For this example, I will create a system assigned identity for my app. It doesn't matter if you use system assigned or user assigned identity.

The main purpose of the AAD admin is to create database specific roles, but we'll come to that. The users in this group will get the db_owner role for all databases on the server, so this should be a highly limited group. For easier management and flexibility, I recommend it to be an AD group, so I've created a group called grp-sqladmin and added myself as member. Set an "Azure Active Directory Admin" for the database server.įirst up, you need to set an AAD admin for the SQL server. I will demonstrate how this app can connect to the database in 5 simple steps.
#Sql server connection string format password
Even if you store these credentials in KeyVault, a password needs maintenance/rotation and it might end up in the wrong hands (for instance if sloppy developers keep the password on their development computers). Traditionally, the connection string to the Azure SQL database contains both username and password.
