Update
Azure Functions need to access on-prem MS SQL Databases via Azure Managed Identity.
Does Azure Managed Identity support this?
Update
Managed identities allows Azure resources to authenticate or authorize themselves with other supported Azure resources.
On-Premise MS SQL Server supports two authentication modes, Windows authentication mode and mixed mode.
Azure Managed Identity does not support your case - Azure Function connection to On-Premise MS SQL Server.

I've got an Azure App Service that needs access to a classic SQL Server (non-Azure SQL, not SQL Managed Instance) and I'd prefer to do this via System Managed Identity. This is enabled on the App Service and a corresponding Enterprise Application is created on Azure AD.
The SQL Server is also connected to this Azure AD and User accounts on the AD already have access to the database. However I can't find how to create a login for the Enterprise Application. If this was an Azure SQL database I could do it with CREATE LOGIN [AZUREAD\app] FROM EXTERNAL PROVIDER but this does not work on a classic SQL Server, only on Azure SQL/MI.
A solution would be to use SQL accounts and reference the login/password in the connection strings, but as mentioned I'd much rather use Azure AD for authentication.
To answer my own question: SQL Server 2022 includes Azure AD authentication Link
Using integrated security or an access token it will be possible to authenticate with an App Registration.
This is currently in preview with no RTM date specified.
I am required to migrate an on-prem ASP.Net web application with its SQL Server 2019 backend to Azure.
The Web application initial migration must be IaaS (Windows VMs running IIS).
The SQL 2019 has to be Azure SQL PaaS (Not Azure SQL Managed instance).
The existing on-prem Web application has several virtual directories, and each application in a virtual directory, is in a separate IIS app pool.
Each app pool is run under the context of a different domain service account.
Connection to the SQL databases is via integrated security.
In the current on-prem solution, the domain service accounts are added as logins to the SQL Server and each has permissions to one or more of the databases (Execute / Connect permissions; addition to datareader role etc).
I believe there will have a domain join to Azure AD, so the on-prem AD service accounts will be accessible in azure (as far as I can understand).
SQL Azure does not support CREATE LOGIN [MYDOMAIN\MYSVCACCOUNT] FROM WINDOWS;
Is there a way I can setup the existing on-prem domain accounts with the access, permissions and roles in the SQL PaaS solution, to mirror the current on-prem setup?
Alternatively, could someone could help me identify resources for best practice for the architecture described.
Thank you
I found a a few good posts that assisted me to understand all available options:

Is there a way to AUTHENTICATE to Azure Sql DB with DBeaver with MFA enabled? Our organization use Azure Active Directory Universal - Universal with MFA to authenticate user to the DBs. Is there a way to use Dbeaver instead of MSSMS?
The tool uses the jdbc driver to connect azure SQL. Now, the driver does not support Azure AD with MFA. So we have no way to do these. For more details, please refer to here and here
Currently I have everything on premise - .NET Core 3.0 API and SQL Server database.
Azure AD/Service account are configured in IIS and database has given access to the service account.
All requests use that Azure AD service account.
Now we are planning for an Azure migration. API is published in App Services.
Now I want to use the same Azure AD account to connect to an Azure SQL Server database.
How should I do that?
Don't send me Microsoft links, those are having toooo much info.
Tell what and how to do configuration in Azure SQL and App Services.
Any help is appreciated.
Now I want to use the same AD account to connect to an Azure SQL Server database.
AD accounts can't connect to Azure SQL Database. Only SQL and Azure Active Directory (AAD) Logins/Users.
There are some options, but there's a clear best-practice: Provision a Managed Service Identity (MSI) for your Azure App Service Application and use that to connect to SQL Server.
Here is a simple tutorial for how you should integrate App Service and Azure SQL Database:
Tutorial: Secure Azure SQL Database connection from App Service using a managed identity
I have an application written in VB, which used to connect with a Microsoft SQL Server, which is placed on a VM in the domain, using Windows Authentication(Local Domain).
But, I have moved my DB to a SQL Server which is placed on an Azure VM.
My problem is that i don't know how i can use Windows Authentication(or somehow to "ask" the Active Directory about the user who tries to connect).
I have seen the modes of SQL Server:
Active Directory - Password
Active Directory - Integrated
but i can't understand how i can use them. Should i have to do trust relation between 2 domain(Local, Azure)?
Can someone help?
I have moved my DB to a SQL Server which is placed on an Azure VM.
SQL on an Azure VM is the same product you might run on-premises, and supports SQL Auth and Windows Integrated Auth. The Azure Active Directory authentication methods supported by Azure SQL Database and Azure SQL Data Warehouse are not applicable to SQL Server running in an Azure VM. See:
Azure Active Directory authentication is a mechanism of connecting to
Azure SQL Database and SQL Data Warehouse by using identities in Azure
Active Directory (Azure AD).
See Use Azure Active Directory Authentication for authentication with SQL Database, Managed Instance, or SQL Data Warehouse
For SQL Server running in an Azure VM you use either SQL Authentication or Windows Authenticationl, as outlined here Authentication in SQL Server
You can use Windows Auth in your VM with either local accounts (created on the VM), or you can deploy a Domain Controller on a separate VM into your VMs VNET and use identities from the Domain. The Domain Controller you deploy into your Azure VNET can be an isolated Domain, or it can be a replica for your on-premises domain. If you want to deploy a replica of your on-premises domain into an Azure VNET you also will need to use a site-to-site VPN or ExpressRoute, as explained here Guidelines for Deploying Windows Server Active Directory on Azure Virtual Machines
