Having the challenge to get the set manager to work.
The permissions are right in my app as long as I have understood.
The app also has the Company Administrator and the Helpdesk Administrator role.
If those roles also have User.ReadWrite.All, Directory.ReadWrite.All everything should be alright?
In Powershell it works (but in another authentification context of course)
Set-AzureADUserManager -ObjectId $user.ObjectId -RefObjectId $manager.ObjectId
Then I can see the Manager with get-AzureADUserManager -ObjectId $user.ObjectId
Content-length is the length of the JSON string, and I calculate it with strlen in PHP. I hope that's correct.
But this gives me no response. Which is normal, I guess. But nothing happens actually. If I enter a wrong email or wrong format in the input, I get a related error message. So a part of it works. But not the set stuff.
