keystone requires pysaml2 4.0.2 (tested with 4.5, didn't pass tests).

I've patched 4.0.2 in r2, let me know if that's sufficient to stablize
Comment 6 Thomas Deutschmann (RETIRED) gentoo-dev 2018-01-11 23:58:30 UTC
Looks like you have missed to patch "verify()" method. See https://github.com/jkakavas/pysaml2/commit/6312a41e037954850867f29d329e5007df1424a5 and https://github.com/jkakavas/pysaml2/blob/4.0.0/src/saml2/authn.py#L180
Comment 7 Matthew Thode ( prometheanfire ) archtester Gentoo Infrastructure gentoo-dev Security 2018-01-12 00:06:55 UTC
ok, fixed in 4.0.3-r3
Comment 8 Thomas Deutschmann (RETIRED) gentoo-dev 2018-01-12 01:26:25 UTC
OK, we now have to stabilize =dev-python/pysaml2-4.0.2-r3. I already updated the GLSA.
