nexpected client assertion type

[lemmycaution]

Hi there,

I'm trying to run client_assertation_certificate_example but stuck with below error. It seems I'm missing something in configuration but cannot find it. Any tip most welcome, thanks a lot.

Seeing the same issue. @lemmycaution did you ever resolve this?

[lemmycaution]

No, sorry. I ended up with using some other platform.

@lemmycaution Thanks

I had this it's an easy fix - if you look through the code of the dotnet version, it uses a different JWT_BEARER string:

https://github.com/AzureAD/azure-activedirectory-library-for-dotnet/blob/2e528e99d50ea3176c968ea95820f6c033b48b59/src/Microsoft.IdentityModel.Clients.ActiveDirectory/Internal/OAuthConstants.cs#L73

Someone's already done a pull request too: #39

In the meantime you can monkey patch the gem to fix:

module ADAL
  class TokenRequest
    module GrantType
      JWT_BEARER = 'urn:ietf:params:oauth:client-assertion-type:jwt-bearer'
    end
  end
end
