I am using an Azure Analysis Services instance and need to grant access to all authenticated users in the domain. The problem is that I don't see any groups within our Azure AD tenant that resemble "everyone" or "authenticated users". It looks like this is something that can be accomplished with dynamic groups, but I wanted to check and see if maybe I'm overlooking a group that is already available in the tenant by default containing all authenticated users.
Thanks,

From https://learn.microsoft.com/en-us/azure/active-directory/users-groups-roles/groups-dynamic-membership:
Create an "All users" rule
You can create a group containing all users within a tenant using a membership rule. When users are added or removed from the tenant in the future, the group's membership is adjusted automatically.
The “All users” rule is constructed using single expression using the -ne operator and the null value. This rule adds B2B guest users as well as member users to the group.
user.objectid -ne null

We have developed a webapp and configured its authentication to use our Azure Active Directory tenant. This works fine. We have clients which are other organizations and when a user from one of those clients authenticates they are presented with content that is specific to their organization. This also works fine.
Under the hood: To accomplish this, in our tenant we have created groups (one for each client) and we have invited users from those clients and assigned them to the appropriate groups (after they are added we have to manually change their user type from 'Guest' to 'Member')
Problem:
If one of our clients signs in to Azure AD they are able to see ALL other groups and all other users. They are also able to add and delete groups and do virtually everything our global administrator account can! This tells me we have done something very very wrong. We are new to Azure AD and there appears to be very much about it that we do not understand.
What I've tried.
Read about administrative units (that doesn't seem to be it)
Roles and administrators: this page has a long list of roles which have check boxes next to them that appear to do nothing.
Home > Tenant > Users > Username > Assigned Roles > Add Assignment: I can select from any of that same list of roles but they are all different kinds of administrators. This would seem to be granting more permissions, not taking them away.
Home > Tenant > Groups > Groupname > Roles and Administrators: This page simply says "no roles found"
Essentially I need our members to not be able to do anything on azure AD except return a list of the groups they are in as well as their own details (name, email, profile picture, etc.)
Assuming you are adding the client users in a specific that group itself already have some admin privileged/Global Administrator/Directory writer Permission.
In that case only user can do operations on group and other users’ data.
Would suggest you check at the Group->Role and administrator & User->Role and Administrator should have only Directory Read permission.
For me in User->Assigned Role->Active Assignment only have Directory Read Role permission so I can only see my details and list of groups that is present in Active Directory but can not do any operation on any group/users like write/delete/update expect read.
Note: To assigned role at the group level you require an Azure AD Premium P1 license.
Update
For assiging role to group please go through in this way---
AAD->Role and Adminsitrator-> Select Role->Add Assigment->Select Member(Group)
Is it possible to add users to different groups based on the url they are coming from. All users to be added under the same Azure B2C directory but under different group during registration.
Example:
www.admin.com - User should go to "Admin" group.
www.user.com - User should go to "Users" group.
Thanks :)
You could use azure ad dynamic user group to do that, when you create a dynamic group with rules, the system evaluates all rules in a directory to see if the change would trigger any group adds or removes. If a user satisfies a rule on a group, they are added as a member of that group.
Reference - Dynamic membership rules for groups in Azure Active Directory
In your case, create the dynamic user group Admin, to add the users to the Admin group, you just need to add the rule like (user.userPrincipalName -match ".*admin.com*."), another one is the same logic.
After the system updated the group completely, it will appear like below.
My goal is to have the user authenticate with Azure AD and then be presented with a drop-down of profiles they want to access. Based on which profile is selected, the user will have different permissions on the site. I'm trying to avoid a user having to have multiple logins to enforce the different permissions per profile.
Can Azure AD handle this or do I need to tie in custom code in a database?
No, Users have one identity and can have a set of roles on an app.
Well, just one role unless you have group-based role assignment available :)
This concept sounds like something you will have to build in your app.
Or you will have to have multiple users registered for this one person.
As you can see my question above, I was wondering if it is possible to retrieve the assigned groups of an Azure Active Directory (AAD) based user via Microsoft GraphAPI.
My situation is, that I have an ASP.NET MVC project with Microsoft Azure enabled. My goal is, that an Azure user can login on my website with it's Azure account.
The idea is, that an azure user is an admin or an user (depending on the azure groups) and depending of this role group, the user can view more or less of my webpage.
For example:
When Peter logs in with his azure account on my webpage, he should only be able to see:
Add new Document
Edit Document
Remove Document
because he is only assigned as "User" in Azure Active Directory.
But when Sabrina logs in with her azure account on my webpage, then she should be able to do the same as Peter, but she also can see:
Manage Products
Add new customer
etc.
because she is been assigned as an admin in Azure Active Directory.
My problem is, that I did not find out how I retrieve the assigned group of an user with Microsoft GraphAPI. The part, which user can see or not after I got the roles is not a big deal.
I already tried this API call:
https://graph.microsoft.com/v1.0/me/
But it seems, that the response of this call does not include the actual assigned group of that user.
Do you think it is possible to retrieve the assigned group of an azure user? Is this even possible? Or do I have to do something else to retrieve these information?
I hope you understand my point and I am also looking forward for any response. Thanks in advance!
Add /memberOf to the URL to receive the groups a user is member of.
https://graph.microsoft.com/v1.0/me/memberOf
Here's a link to the specific graph api - https://developer.microsoft.com/en-us/graph/docs/api-reference/v1.0/api/user_getmembergroups
Take a look at this sample application on Github. It does something very similar with a task tracker application, where different users are able to perform different actions based on the group they belong to -
https://github.com/Azure-Samples/active-directory-dotnet-webapp-groupclaims/blob/master/README.md
Also, in cases where a user is a member of too many groups, you get back an overage indicator and have to make a separate call to get all groups. Read about “hasgroups” and “groups:src1” claims here - https://learn.microsoft.com/en-us/azure/active-directory/develop/v1-id-and-access-tokens
According to your system architecture, if some user has too many joined groups, the API https://developer.microsoft.com/en-us/graph/docs/api-reference/v1.0/api/user_getmembergroups will return too many groups.
But if the groups with permissions in your system are not too much, you can use this API: https://developer.microsoft.com/en-us/graph/docs/api-reference/v1.0/api/user_checkmembergroups to check if the current user is the member of specified groups.
It is not good idea to use this API: https://graph.microsoft.com/v1.0/me/memberOf. Because it returns only the groups that the user is a direct member of, but security group can be member of security group.
I can Authenticate user in Active directory but I need to know can we authenticate a specific user in group if we have multiple groups.
Basically I am redirecting to http://[mydirectory].onmicrosoft.com and validating the user but I need to know do we have mechanism to validate a user from specific group so that I can give access according to that.
Assuming this is Azure AD (and not on-premises Windows Server AD), then you have three options to restrict access to an application via groups.
Option 1: Require user/group assignment to application
This is the only option that does not require adding authorization logic in your application.
When configuring your application in the classic Azure portal, you can set the application to require user assignment:
Then, under "Users and Groups" for that application, you can choose which individual users or groups should have access to the application.
The most important thing to consider here is that this will only apply to direct members of the group, not to nested members.
Option 2: Request group claims
This option will allow you to request that the token returned to the application after a user has signed in contain the list of groups that the user is a member of. This includes groups that they are transitive members of (i.e. nested groups).
From your application's configuration page in the classic Azure portal, you can download and upload the app's manifest JSON file. In the manifest, locate the "groupMembershipClaims" attribute, and set it to "All" or "SecurityGroup" (the latter will exclude distribution lists).
Once this is set, after the user signs in, the resulting token will have a groups claim that contains a list of group object IDs that the user is a member of. Your application can then use these claims to decide whether or not the user should have access.
Dushyant Gill goes into group claims in detail in his blog post: http://www.dushyantgill.com/blog/2014/12/10/authorization-cloud-applications-using-ad-groups/ (archive.org link)
The important consideration here is that there is a limit to the number of groups that can be returned. If the user is a member of more groups that this limit, then an "overage" claim is issued, and your application will need to make an Azure AD Graph API call to get the full list. (This is also described in Dushyant's blog post.)
Option 3: Use the the Microsoft Graph API or the Azure AD Graph API directly
The final option is to simply call the Microsoft Graph API (or the Azure AD Graph API, they both act almost identically for this) to establish if the signed in user is a member of a given group. Your application can then make the authorization decision.
There are several approaches you can take (these are all transitive checks, so nested groups are supported):
isMemberOf to check whether a the user is a member of a specified (single) group. This is the simplest if a single group should grant access to your app.
checkMemberGroups to check if the user is a member of any groups in a list of groups. This is useful if different groups grant different roles or permissions in your application.
getMemberGroups to return the full list of groups the user is a member of. This is generally not particularly useful for doing authorization checks.
