Aarhus municipality does not support RequestedAuthnContext so we need to apply the patch Aarhus-municipality-does-not-support-RequestedAuthnContext.patch to the contrib module saml_sp:
cd profiles/loopdk/modules/contrib/saml_sp/
curl --location --silent https://raw.githubusercontent.com/os2loop/profile/master/patches/Aarhus-municipality-does-not-support-RequestedAuthnContext.patch | patch --strip=1
