Hi, I'm new to using SAML with django and I was following the tutorial at https://developers.onelogin.com/saml/python. Last friday, I was able to set it up and login through onelogin to the demo django app. However, 4 days later, I started getting

invalid_response
Reason: Deprecated signature algorithm found: http://www.w3.org/2000/09/xmldsig#rsa-sha1

errors while trying to authenticate to onelogin from the same app. To check again, I set up another app from the same tutorial and I still get the same error. The webpage looks like below:

What could be the reason?

Making these changes in advanced_settings.json helped fix the problem.

"rejectDeprecatedAlgorithm": false,
"wantAttributeStatement": false

However, it did not feel right to change these to false as this could bring security issues. Any recommendations?

At the IdP, you can define how the SAMLResponses gonna be signed, select a non deprecated algorithm. (SAML Signature Algorithm field)
