How can I use automatic NTLM authentication from python on Windows?
I want to be able to access the TFS REST API from windows without hardcoding my password, the same as I do from the web browser (firefox's network.automatic-ntlm-auth.trusted-uris, for example).
I found this answer which works great for me because:
It's using the WinHTTP.WinHTTPRequest.5.1 COM object to handle authentication natively:
import win32com.client
URL = 'http://bigcorp/tfs/page.aspx'
COM_OBJ = win32com.client.Dispatch('WinHTTP.WinHTTPRequest.5.1')
COM_OBJ.SetAutoLogonPolicy(0)
COM_OBJ.Open('GET', URL, False)
COM_OBJ.Send()
print(COM_OBJ.ResponseText)
You can do that with https://github.com/requests/requests-kerberos. Under the hood it's using https://github.com/mongodb-labs/winkerberos. The latter is marked as Beta, I'm not sure how stable it is. But I have requests-kerberos in use for a while without any issue.
Maybe a more stable solution would be https://github.com/brandond/requests-negotiate-sspi, which is using pywin32's SSPI implementation.
NTLM credentials are based on data obtained during the interactive logon process, and include a one-way hash of the password. You have to provide the credential.
Python has requests_ntlm library that allows for HTTP NTLM authentication.
You can reference this article to access the TFS REST API : Python Script to Access Team Foundation Server (TFS) Rest API
If you are using TFS 2017 or VSTS, you can try to use Personal Access Token in a Basic Auth HTTP Header along with your REST request.
