WsTrust server returned error in RSTR

[quentinhardy]

Hello,

I have used:

python3.10 spray365.py generate normal -ep ex-plan.s365 -d dom.de -u users.txt -pf pwds.txt

It is a fresh install.

python3.10 spray365.py spray -ep ex-plan.s365

It seems the msal library has been modified. I think authentication now requires a UPN, an not a username only.

Best regard,

Seeing similar behavior on my end, but only in specific situations. I believe this is not related to UPN specification, but instead redirects caused by federated identity providers such as Okta, ADFS, OneLogin, etc. I have also seen this happen when a GSuite account accidentally makes its way into my spraying list. When attempting to log in with your "testaccount" above via a browser, are you redirected to an alternate login portal?

Let me know if not, and I can try to make some code modifications to specify a UPN to share here.

Regardless, we need to work on error handling in spray_exception_wrapper.py. It needs some work to better pass on/handle more fringe errors produced by msal.
