I have created an App role for my AZURE AD Backend Api and assigned this role to a group. Now I want to authenticate user in my .net core backend application on the basis if user has a group which has this role. I am getting the group ids in the access token but how can I get app roles assigned to these groups.
Please check how you enabled group claims in Azure Portal.
If you check the Emit groups as role claims option like below you cannot see application roles, but you can see group ids.
If the above option is enabled, make sure to uncheck the box.
Note
If you use the option to emit group data as roles, only groups will
appear in the role claim. Any application roles that the user is assigned to won't appear in the role claim.
Also, I would suggest you refer to this Microsoft official documentation below which states that if you add a service principal to a group, and then assign an app role to that group, Azure AD does not add the roles claim to tokens it issues.You can modify the “groupMembershipClaims” field in application manifest if you want to include groups claim in your token like below: -
Add app roles to your application and receive them in the token
For more in detail, please refer below link:

net core application and trying to implement authentication and authorization. I have set of users and these users belong to different regions. For example I have region APAC and I have some users in it. Then I have roles like global admin or regional admin. Now these users are type of regional admin global admin etc. Now I want to return role claim in my token. To return role claim in my JWT token I should add app roles in manifest. So how should I return app roles now. If I select as group then all users belong to that group emits this role details. I am little bit confused here. I have grouped users according to regions. Inside each region users are of type regional admin, global admin etc and they have different permissions inside app. Segregation of these groups vs roles I am finding lot of challenge and no use full document also I found. Can some one help me to segregate these groups vs roles.
As I understand you have users with different roles under the groups segregated by the regions. When you are trying to authorize by group all the users with different roles of the group emit the group role details.
Assuming regional admin you mentioned as a custom role for your application(as there is no such role in AAD) following is a suggestable approach.
A user can be assigned to multiple groups and Roles can be assigned to individual users/groups.
Create groups separately for regional admin, global admin users and assign roles to these groups accordingly.
If you are using the role claim in the token for role-based access control, authorize applications based on the role permissions granted by the administrator to groups. Please refer this link for the detailed documentation on how to create/manage roles for an application in Azure AD.
I have an application registered on Azure AD. The application has been configured to include groups claim on Token Configuration section on Azure Portal. When I access to the application, follow the process to authenticate against AzureAD, and access to an Controller endpoint, I see that the Claims for the user property does not have the groups. Instead, I'm getting a property, hasgroups, defined with true.
I'm assigned to 89 groups, I don't know if there's any limitation about the number of groups and for that reason Azure change the claims (instead one for each group, it's emitting one with the boolean value I have told you).
This situation happens with an organization tenant. I have test the same with my own tenant on Azure and I'm getting the groups. But in my own tenant I'm assigned only to 2 groups. This is the reason I've highlighted the number of groups i belongs to in my organization.
There is a limitation to how many groups can be returned due to size limitations of tokens.
You must always be ready to query for user groups from MS Graph API, e.g. with:
Get group members: https://learn.microsoft.com/en-us/graph/api/group-list-members?view=graph-rest-1.0&tabs=http
Get user groups: https://learn.microsoft.com/en-us/graph/api/user-list-memberof?view=graph-rest-1.0&tabs=http
Check group access for user: https://learn.microsoft.com/en-us/graph/api/user-checkmembergroups?view=graph-rest-1.0&tabs=http
If you get the hasgroups claim, you need to query for groups.
I can't understand how to create custom roles in fusionauth. I want to create my own set of roles and put them in respective groups.
Are roles and groups are synonymous in fusionauth ? I see roleIds object inside groups but can't find much detailed documentation on that.
Also jwt token has roles[]. Is it possible to return those custom roles in jwt token?
Any help is appreciated.
You may use the UI or the API to create roles for an application. When you create an Application in FusionAuth you may create the roles at the same time. The UI link above is a tutorial to create an application in the UI.
The roles for the default application FusionAuth cannot be modified. This application represents the admin user interface. You will create at least one application that represents your application.
Are roles and groups are synonymous in fusionauth ?
No. Roles belong to an Application. An application in FusionAuth represents and authenticate resource. A Group is a logical grouping of users, and a way to manage roles across multiple applications.
To manage roles for an Application once it has been created navigate to the Application Roles. Settings --> Applications --> Manage Roles The Manage Roles button is the dark blue one in the row action.
The FusionAuth Group can be used to assign roles from multiple applications to a user through Group membership.
For example, assume you have multiple Applications, Support Portal and Workday, and each of these applications contains an admin role.
A FusionAuth Group could be created called Admins and it would be assigned the admin role from Support Portal and Workday.
A User can be assigned the admin role for both of these Applications through Group membership. The user will still require a registration to the application to receive the roles assigned to the Group. This mechanism provides a way to manage role assignment for groupings of users.
The roleIds inside of the Group object is how the API will interact with Application Roles. If you utilize the UI you can just point and click.
Also jwt token has roles[]. Is it possible to return those custom roles in jwt token?
The roles assigned directly through a User Registration or by Group Membership will come back in the JWT in the roles claim when logging into a specific Application.
I am using Azure AD B2C and I want a group based user distribution for my application. Lets say I have two subdomains subA.myapp.com and subB.myapp.com. On the other hand, I have two groups subA and subBin Azure B2C. Now a user wants to signin to subA.myapp.com, but is not a member of group subA, I would like to deny the user to sign in.
I know that Azure B2C does not include group info in the access token. So I will actually use Graph API to get the group membership of the user. But I am not quite sure if there is an appropriate event where I could intercept the validation process and manually deny a user to sign-in. Also, I thought I could use one of the *Validator methods of TokenValidationParameters but not sure which one.
I have read Authorize By Group in Azure Active Directory B2C. My problem is different because that problem is trying to protect only some actions based on group memberships, I want to prevent the whole login process to fail based on group membership.
You can use a ValidationTechnicalProfile on a page created by the SelfAssertedAttributeProvider technical profile. Using the validation technical profile, you can first authenticate the user, and then call a Rest API that can look up users group membership and return a successfull/fail response.
If the response is successful, the flow will continue. If it's a failure, an error will be shown to the user.
I am new to Keycloak and I try to use it as authentication server in my solution.
I have the following entity's model: the devices are owned by a particular company to which some users belong. User with role admin can grant permission for viewing some set of devices to a regular user but only those devices that belong to the admin's company. Thus all users except admins can view only a subset of all devices in company.
Based on these requirements, I decided to make companies as groups and devices as Keycloak's resources. To evaluate permissions, I chose rule based policy.
The question is -- Can I set group as an owner of resource to check this relation in policy?
If someone is more experienced in keycloak and knows how to better represent such model, please help.
Thank you in advance.
As working on keycloak, I didn't find any way to set the multiple owners for particular resources.
I'm having the alternate option to give the access permission, that owners have for their resources.
Let say Resource A owner is OWNER A, now there are two more user USER A and USER B. If suppose OWNER A already share the access permission to USER A and USER A wants to share Resource A to USER B on behalf of the Resource owner, then how should USER A can share the resource scopes to USER B?
Answer
Keycloak provides the facility of token exchanging or impersonation feature. With the help of this USER A can able to share the resources to USER B on behalf of the OWNER A (Owner of Resource A).
Reference: You just need to follow this Keycloak Impersonation
Add comments if you still face the problem
In Keycloak, you may represent a particular company (or any organization or organizational unit) as a realm:
https://www.keycloak.org/docs/latest/server_admin/index.html#core-concepts-and-terms
Create a new realm:
https://www.keycloak.org/docs/latest/server_admin/index.html#_create-realm
Then represent the company's users as users in the company's Keycloak realm
https://www.keycloak.org/docs/latest/server_admin/index.html#user-management
... and devices as Keycloak Clients (any kind of resource you want enforce permissions on is a Client in Keycloak model):
https://www.keycloak.org/docs/latest/server_admin/index.html#core-concepts-and-terms
An admin role is already defined by default for each role (Roles menu).
Instructions tested on Keycloak 4.0.0.
For each device, create the corresponding Client in Keycloak (Clients menu). Switch on Permissions Enabled on the Permissions tab of the new client. A list of admin console permissions will appear just below the switch button, such as the view permission.
Then, in order to assign the permission to view the device to some user, the admin should click on the view permission (link) just mentioned, create a User Policy (Create Policy... listbox) and select the users (assignees) in the Users field.
In order to assign the permission on multiple devices to the same group of people, use a Group or Role Policy instead (put the users in the same group before).
In order to assign the permission to groups of devices, use one Group/Role per group of device, then assign users to the Group/Role.
