I have a SharePoint Server 2010 site setup with SSL. (https://sitename.com) Whenever someone tries to save an Excel or Word document to the site through Save As or Save To SharePoint they get "Mutual Authentication Failed.
The servers password is out of date at the domain controller". The desktop experience feature is installed and the webclient service is running. They also receive certificate is not available and if they wait a little bit or hit OK it will show the directory
and not the website like on a regular http site.
