'NoneType' object has no attribute 'token_type'

I am trying to get access token via acquire_token_with_username_password in python 2.7, but I get the following issue:

  File "E:\Projects\python\adal\adal_test.py", line 8, in <module>
    '994e5ec6-28f2-45b3-a892-c9131b266a05')
  File "E:\Projects\python\adal\adal\authentication_context.py", line 125, in acquire_token_with_username_password
    return self._acquire_token(token_func)
  File "E:\Projects\python\adal\adal\authentication_context.py", line 89, in _acquire_token
    return token_func(self)
  File "E:\Projects\python\adal\adal\authentication_context.py", line 123, in token_func
    return token_request.get_token_with_username_password(username, password)
  File "E:\Projects\python\adal\adal\token_request.py", line 265, in get_token_with_username_password
    token = self._get_token_username_password_federated(username, password)
  File "E:\Projects\python\adal\adal\token_request.py", line 243, in _get_token_username_password_federated
    username, password)
  File "E:\Projects\python\adal\adal\token_request.py", line 210, in _perform_username_password_for_access_token_exchange
    return self._perform_wstrust_assertion_oauth_exchange(wstrust_response)
  File "E:\Projects\python\adal\adal\token_request.py", line 182, in _perform_wstrust_assertion_oauth_exchange
    grant_type = _get_saml_grant_type(wstrust_response)
  File "E:\Projects\python\adal\adal\token_request.py", line 55, in _get_saml_grant_type
    token_type = wstrust_response.token_type
AttributeError: 'NoneType' object has no attribute 'token_type'

And my code snippet is like:

import adal
context = adal.AuthenticationContext('https://login.microsoftonline.com/<tenantID>')
RESOURCE = '00000002-0000-0000-c000-000000000000' #AAD graph resource
token = context.acquire_token_with_username_password(
    RESOURCE, 
    'username',
    'paddword',
    'aad_clientId')

print token
refresh_token = token['refreshToken']

I cannot figure out why. Could you help me to fix it.

@Walk4Muscle, your account is federated. It is more recommended to use interactively login, check out the sample. Let me know whether this works for you.

[Walk4Muscle]

So which type of account I can use in the acquire_token_with_username_password function?

[yugangw-msft]

For non-federated accounts acquire_token_with_username_password should just work. For federated accounts, those identities provided through on-prem servers, it is complex because it involves the ADFS server configuration. If you have test accounts we can repro this issue, that will speed up the diagnosis. I can be reached by email: yugangw at microsoft dot com
/CC: @addev-ashish, can you ask your team for whether this is a known issue?

[yugangw-msft]

Also, if you have accounts with 2 factor authentication enforced, acquire_token_with_username_password won't work as well. Interactive login work for any account types.

Dear yugangw, I have the same problem. Login per credential (username/passord) - without user interaction - is required if a service do the data exchange. I can provide you a test account. Thanks. BR MIT

[yugangw-msft]

@MIT02 I should submit a fix on early next week.

[yugangw-msft]

@MIT02 , @Walk4Muscle, it will take some more days to get the package published out, but you can try out by installing the package from git
pip install https://github.com/yugangw-msft/azure-activedirectory-library-for-python/tarball/federated
And let me know if you see any issues.
The change includes the fix for this issue, and also improves the support on federated accounts particular on wstrust 2005.

fixed in 0.4

@vogranovic, are you getting the same stack trace?
