Configure Link to use Azure AD authentication

Enable Azure AD Authentication

• Open the Link website root folder.

• If you created the application as single tenant you have to replace “common” in the azureADLoginUrl with your tenant ID.
  

  Code Block
  { "azureADClientId": "6014aee9-5bb6-40a2-84cb-6a3af0036ac2", "azureADLoginUrl": "https://login.microsoftonline.com/common/oauth2/v2.0/authorize?prompt=select_account&response_mode=fragment&response_type=token&scope=https://graph.microsoft.com/groupmember.read.all https://graph.microsoft.com/user.read&nonce=abcde" }

• Recycle the IIS application pool.

Setup Link User Groups

When a user logs in to Link for the first time using Azure AD authentication, Link will create a new user and assign one or more user groups. Which groups depends on what AD groups the user is member of. On a link user group it's possible to specify a Domain Account. If a user has an AD group with that name the user group will be assigned to the user.

...

NOTE: If the Azure AD group is synchronized from Windows AD, Domain account name might need to be prefixed with the Domain name eg: DOMAIN\Developers

Specify Azure AD tenants to accept logins from

• The Link login dialog should now look like this
  

  

• Click Sign in with Microsoft and enter your credentials.

• The first time you sign in you will be presented with the following message
  

  

• To allow logins from the tenant edit the table [Users].[tAzureADTenants]. The row has already been created but you need to specify a DataOwnersId and set Approved to true.
  

  

• Now users from the Azure AD tenant can login to Link.
