Custom NTLM client in ABAP

NTLM is a protocol used to authenticate against a variety of Microsoft products.

NTLM is not a recommended authentication protocol, but sometimes it’s the best there is.

Now it’s possible to do NTLM authentication over HTTP via ABAP!



I started the project back in 2015, and now it finally polished, thanks to @kvtorp


For each commit to the open-source project, abaplint is triggered to perform static analysis and style checks.

Additionally, all unit tests are executed for each commit! The unit tests run on GitHub Actions, see the workflow configuration.

And as always, don’t write custom crypto, but sometimes there are no good alternatives.
