Hi,
We have a serious issue with SharePoint 2013 after installing the latest version of Secure Authentication. It worked fine before, it works fine when the management and authentication components are the latest, 2.5.23.0 version and SharePoint is left at 2.4.13.0.
Once we upgrade(uninstall old 2.4.x and install new 2.5.x), SharePoint is having issues. It works fine until a user(no matter if he has 2FA enabled, or disabled) press "refresh" in his browser. After a "refresh", the page does not load correctly anymore, keeps loading, like it would wait for some very long process to respond etc., but finally it does nothing anymore and the only solution is to close the browser and start again.
We tested few different browsers, cleared cache, cookies etc. Nothing helped. Once I downgraded(uninstall 2.5.x and install 2.4.13.0) we are unable to replicate the issue anymore so it clearly is something with the latest 2.5 version.
Is there something special you have to do for the 2.5 ESA version to work with SharePoint 2013? The installation wizard went just fine without any warnings and errors.
