We're seeing an issue with repeated attributes causing auth failure for some IdPs, and need to take some time to investigate. See unpinning issue https://github.com/openedx/edx-platform/issues/32327 for details. This is expected to reintroduce some bugs in testing SAML in devstack. This has the effect of reverting the following PRs: - Unpinned: https://github.com/openedx/edx-platform/pull/32167 (partial) - Upgraded: https://github.com/openedx/edx-platform/pull/32168 However, we're keeping the safe_lxml adjustments from the first PR, so it should be fine on that front to re-upgrade whenever we're ready.
