I have a Microsoft Teams group tab and I'd like to implement a permission system in which users can do different things in the tab depending on their role in the team (or channel). The context I get from the Teams JavaScript API cannot be trusted, so I have to check group/team/channel role through the MS Graph API.
The only way I've found to check whether a user is an owner or only a member of a team is to call /teams/{groupId}/channels/{channelId}/members. In the response I can see which roles users have and I so I can find out if the current user has owner privileges.
The problem is that this endpoint requires admin consent (I guess because it displays data of other users). I'd like to avoid having to ask for admin consent, however. Is there another way of finding out about the role of a user in a team without admin consent? (As private channels behave differently in Teams, this would be the same as finding out about the role in a channel)
I know that I can get if a user is in a group through the optional group claims that are added to the ID token but this doesn't include the rule inside the group/team/channel.
To read a user's role in a channel currently requires admin consent, the permission needed is ChannelMember.Read.All see list conversation member documentation here. Admin consent is also required to get a member of a team or list members in a team. For your particular use case, I would recommend asking your admin to grant these permissions.

Inviting a consumer user to Azure AD B2C has been covered by other Stack Overflow questions & answers, and AFAIK requires the use of custom policies that entail a signed JWT being created and used during invite redemption.
What I'm trying to figure out: In our application, we have differently permissioned user groups and different organisations managed by internal RBAC logic. We identify & authorize users based on their oid claim in the access token that's returned to msal-react/msal-browser and used to authenticate against our backend's API.
In Microsoft Graph, a user can be invited and the API will respond with the created user's oid. However, this is the wrong type of user and not appropriate for B2C scenarios.
With the custom policy route not creating the user object in AAD B2C at the time of invite, and therefore without knowing the user's oid at the time of inviting them to the application, what might be the best way to configure their in-app profile and have them identifiable to the application itself upon first login?
My thought at the moment is to have the application store the emails of users that are invited who have not yet redeemed/signed-in. We can configure the emails claim to be returned upon login, which is checked against the invited emails store when an oid claim is returned that isn't present in the database. This can then trigger a function to update the user's internal id with the oid in their first login's claim.
If this is inadvisable or if there's a better way, I'd be very grateful to hear it.
It would work, or just pre create the user up front via MS Graph API. Then you have an email and objectId available.
You could also put an extension attribute on the account indicating whether the user has redeemed their invite. That would allow you to monitor who has redeemed, and also be a way to provide a different experience depending on if the user has redeemed or not redeemed the link.
I need to emit a role's permissions as claims in the JWT.
The aim is to get a certain user's permissions as claims in the JWT for authorization purposes.
The user belongs to a group which is assocciated to a certain role which has certain permissions in the Azure Active Directory.
Clarification:
If I add some items to the appRoles array in the app's manifest, the role names are emitted as role-type claims in the JWT in the following format:
http://schemas.microsoft.com/ws/2008/06/identity/claims/role: [value property in the appRole item as appears int he manifest appRoles array]
But I couldn't find any way to emit role's permissions' names (or any other property) as claims.
I've been googling and digging in MS docs for days but couldn't find anything. I hope that it's possible.
If it isn't possible, a clumsy workaround may be to represent the permission we need to be emitted as an AAD role, and to represent the role (in the meaning of "a set of permissions") as an AAD special group, and then to associate the groups we wanted to be associated with the role (in an ideal world) to that special "role"-group.
But it's very clumsy as we will actually lose the natural meaning of role which is a set of permissions, and the natural meaning of group which is a set of users and/or groups
Thanks for any help :)
The value property is the custom role name you configured and will be returned in JWT. It's by design.
The permission name won't be returned in the JWT. After you have added an appRole into the Azure AD app, you need to assign users and groups to the role.
You need to add the needed permissions in Azure AD APP and then control the permissions in your code.
We assume you have assigned a custom role in an Azure AD app and added a user to this role.
When a user signs in, a token which includes the role claim will be returned. You can judge the user's role in the code. If it matches a custom appRole, he is allowed to perform an operation. If the user does not match any of the appRoles, he does not have permission to perform any operations.
I am added to project collection administrator group in VSTS. Still not able to add a new user. I am added using my official email ID i.e. Microsoft work account.
Its says
Guest users are not allowed to perform this action.
I saw the reason on this link
I believe the primary reason for this error is because when a co-admin
with Microsoft account is added to a subscription, it gets added into
the subscription AD as Guest user type.
but since it is very old thread i like to know if there is an easy way to get myself ability to add new user or basically manage VSTS on behalf of client. I hate requesting client to add a new user in team. Also he is not tech savvy so I would like suggest him a simple solution (running Powershell might be annoying for him).
You are inviting users from outside directory. The user will be able to access the account and its resources, so you need the enough permission to add new user to the AD, but you are the Guest user, so it throws Guest Users are not allowed to perform this action.
You need to contact to the corresponding user (e.g. AD admin) to add users to AD or grant the enough role and permission to you to add user to AD.
No easy way to do this, because it is related to security.
I hope you're fine, this is my first question and I really don't know where to start from, so here it is,
I've been trying to build a sample with Microsoft Web api Template where I have to authorize users based on roles for example "Admin, Moderators, etc..." so, the thing is the I don't want to put all those roles on the top of the controller like
[Authorize ( Roles ="Admin, Moderators, etc...")]
I see this as not a good practice because What happens if I create another role in my db? I will have to modify the controller to add the new Role xD, really bad, isn't it? so the question is. How to extend some class like AuthorizeFilter to get the roles from database and validate with the controller? I mean if there is a user who is in the role admin authorize it and viceversa?
the other question is How to build a great authorzationfilter which can manage something like if a user if in Moderator Role but the only right he has is to user the Create action in the controller?
I hope you can help me with an example...
Thanks in advance
Ps. Sorry for my english
I agree role based authorization is somehow limited and authorize attribute is a bit rigid.
In some scenarios role based authorization is not enough, you need to extend it. You can introduce the permission concept. Instead of be a requirement that you have to be a member of a specific role to execute an action, you could state that to be authorized to execute an action you need a specific permission. So instead of authorize attribute you use RequiredPermisionAttribute. Of course you need to write RequiredPermissionAttribute as an authorization filter.
In the database you have the Permissions Table, the RolesTable, the RolePermissions table and UsersInRole table.
So a user can be a member of one or more roles. A role can have one or more permissions. A user has a specific permission if he/she is a memeber of a role that has that permission.
The required permission filter checks if the logged in user is a member of a role that has the permission, if not, then returns 401 not authorized.
This is a more flexible approach, actions are not tied to roles and roles don't have a fixed number of permissions.
I am new to the framework cakephp and I am using the Authentication component as well as the ACL. I have followed this tutorial: http://book.cakephp.org/2.0/en/tutorials-and-examples/simple-acl-controlled-application/simple-acl-controlled-application.html to get me started.
How do I give a not logged in User a role (group) ACL such as 'Guest'?
Should I even consider giving a not logged in user such a role (group) ACL? I mean would it bring any disadvantages?
Usually you would not give a role to a user that is not logged in, because the user would not have a record in the user table therefore the User could not belongTo a Role. If you wanted to do alot of special programming I guess you could do it, but I don't see a point.
Most people just allow non-authenticated and authenticated users access to various parts of there app with the $this->Auth->allow() parameter in the controller. Then they section off other parts of the application to allow certain authenticated Users belonging to certain Roles to access with ACL.
