I am having a very tough time figuring out the permissions in my database. My users gain access to the database through reports on SharePoint (via Impersonated authentication configured through Kerberos). Users, who are impersonated, are all added to AD Groups. And in my database, I am granting permissions to the AD GROUPS (as logins) and NOT to the individual users. I have 1000 users but 10 AD Groups. Each user is part of an AD Group.
The users currently cannot have access to the database – they are only able to see the database if I was to add them individually as logins (obviously not an option). If I add their AD Group, it doesn’t seem like it works. Again, they are authenticated through Kerberos as impersonated accounts. Here is a map of what I’m saying:
IF the AD GROUP has permission, why doesn't the user within has permission??
I reviewed this question, but I'm not sure where is the equivalent for SharePoint Integrated mode.

We implemented SSO on Snowflake and with SCIM, we're able to provision users in Snowflake
Now, I want it to work like SQL Server authentication where I can add users to the same AD group and create a single login on SQL Server for this AD group. To revoke login permissions I just remove the user from the AD group. To give a new person access I just add them to it.
I would like also to map a role to a group, so, for instance, if I could link an Azure AD Group to a Snowflake Role [Read-Only User for Database X], as soon as I'm adding a user Y in Azure AD Group, this user Y will have automatically read-only access to Database X
Is it possible ?
Regards,
This same concept is possible in Snowflake as well with SAML SSO (for authorization) and SCIM (to sync users and their corresponding roles to SF). The details for this are here:
https://docs.snowflake.com/en/user-guide/admin-security-fed-auth-configure-idp.html
https://community.snowflake.com/s/article/HOW-TO-Setup-SSO-with-Azure-AD-and-the-Snowflake-New-URL-Format-or-Privatelink
https://docs.snowflake.com/en/user-guide/scim-azure.html
Both these together will ensure that the user created on Azure AD will be possible to login with the AAD credentials and the SCIM will ensure that the relevant role management is on the AAD side which is reflected exactly as-is on the SF side.
I'm not able to access any tabs in AAD. What could be the issue?
Please check if below points can be worked around in your case.
Buttions or options being greyed out maybe because , you may not have had global admin rights/user administrator rights on the azure AD tenant. There are a few roles which can create users within the directory. You may not have any roles within the directory which permit the operations.
Reference: github issue.
Even in Azure AD free edition ,one should be able to create the users if you have proper roles .
On completion of the first 30 days of Microsoft Azure’s free trial,
your ‘Free Trial’ Azure Subscription will be disabled. To fix this,
the subscription needs to be changed to the ‘Pay-As-You-Go’ plan
instead of the ‘Free Trial’ plan which it is currently on.
For example :For applications under Enterprise application, one of the following roles: Global Administrator, Cloud Application
Administrator, Application Administrator, or owner of the service
principal.
You can check Azure AD built-in roles, and by checking the
description of role , assign the required one to manage identity .
You can Assign Azure AD roles to users to manage the identities
if you have global or role administrator rights. Approach the
admin to assign the roles .Also see custom roles in Azure AD
if needed.
Please check if this issue in - Microsoft Q&A can relate .
If issue still remains you can raise a support request in troubleshoot+support blade.
I have made a Simple CRUD application made in VB with the data stored in SQL Server on my local machine.
Within the Database security I have made Database Roles and assigned permissions accordingly, and added my (Domain) Computer user account into the Role.
My connection string is;
Data Source=(LocalDB)\MSSQLLocalDB;Initial Catalog=Assets;Integrated Security=SSPI
Now when I run my application it assumes the dbo role instead of the user who is running the application. As this is intended to run on a central machine and have multiple users connecting to it, with different permissions, what changes do I need to make so that I connect using my domain user account?
When I run commands in SSMS with the EXECUTE AS USER command the permissions apply.
If you want users to connect via their Windows login, your connection string is fine. However, you need to recongifure your security model. Ideally, you'll want to create one Active Directory group per application role. Then, you'd add users' Windows accounts to the appropriate AD group. Now, on SQL Server, you'd add the AD groups to the appropriate database roles.
For example, you create a database role "db_read_only". You'd create an AD group "MyApp.ReadOnly", using your company's AD group naming convention of course. You'd then add MyApp.ReadOnly to your database's db_read_only DB role. Then, John Doe wants read-only access to your app, so he'd request to be added to AD group MyApp.ReadOnly.
Your app roles define how many AD groups and DB roles you'd need. You might have MyApp.Admin, MyApp.DataEntry, MyApp.Approver... whatever.
I am using differential query (AzureAD graph API) to detect changes in Azure AD from the last sync. I am getting all users, group memberships, manager changes. Only missing information is Directory Role assignment (e.g Billing administrator, SharePoint administrator etc).
How can I detect a change in roles of any user?
API - https://graph.windows.net/{org}/directoryObjects?api-version=1.5&deltaLink=xxxxxttttxxxxxxxx
First, if you have enabled those Directory Roles, you can use AAD Graph API operations on directory roles to list members of those roles.
GET https://graph.windows.net/myorganization/directoryRoles/{object_id}/$links/members?api-version=1.6
But, This API can also list service principals which assigned this role.
Situation:
A Windows user is member in multiple AD groups.
Every AD group is mapped to a SQL Server login.
Every SQL login is mapped to a database user.
Every database user has specific roles.
Question:
Is it possible that a Windows user is logging into SQL Server (using WinAuth) and that he gets all roles which he could get due to his membership in multiple AD groups?
Yes. A user's permissions on an object is the union of all permissions paths s/he qualifies for (including any DENY permissions). A quick way to verify is by using the sys.user_token and sys.login_token views as well as the sys.fn_my_permissions function. From an administrative perspective, these work especially well because they are accurate under impersonation (i.e. execute as login = 'yourDomain\someUser').
