Sorry if this has been asked before, but I searched and couldn't find anything. A clients EPiServer 4.61 installation all of a sudden fails all authentication attempts on all accounts. A server reboot does not help, and as far as I know, nothing has been changed on the server (except perhaps content changes). I don't have physical access to the server (nor can I log in remotely), so I would like to know, is it possible to turn on detailed debugging information about why an authentication attempt fails?
