I recently upgraded to Ubuntu 13.10 (64bit) on my Dell Laptop. Since then, at each login, a dialog window entitled "Authentication request ... Please enter the password for account "...@gmail.com"." appears (I would rather post a screenshot if I could, but I am not entitled to do that because I do not have the necessary 10 reputation credits). I neither have any idea why my password (I checked it a hundred times) does not work ("Password was incorrect") nor why this dialog is displayed at all. As said, I never saw it before 13.10. I looked around in different forums and it seems (please correct me if I am wrong) that it stems from evolution server. I also deleted ~/.config/evolution/ entirely - without any effect. Further note that I am not using evolution at all and I would rather like to get rid of it completely, but I do not dare to remove evolution-server.
Thanks in advance, Ulrich
