Description of problem: Recently, Chromium started to complain about web certificate on IPA server. Error NET::ERR_CERT_COMMON_NAME_INVALID talks about [missing_subjectAltName]. It was working correctly since recently. IPA CA certificate is added to system trust database. Similar issue was reported to the mailing list recently: https://www.redhat.com/archives/freeipa-users/2017-April/msg00195.html Version-Release number of selected component (if applicable): freeipa-server-4.4.4-1.fc26.x86_64 google-chrome-stable-58.0.3029.81-1.x86_64
A workaround exists via Chrome policies: https://www.chromium.org/administrators/policy-list-3#EnableCommonNameFallbackForLocalAnchors For example, on macOS: defaults write com.google.Chrome EnableCommonNameFallbackForLocalAnchors -boolean TRUE
