We recently had the following problem with SharePoint 2013:
User A suddenly was logged in on his computer with the name of another user (user B). Both use Windows 7 and Google chrome as browser.
User A claims, that he just opened a Link to the SharePoint portal in his browser and was logged in automatically.
How is that possible?
How could we reproduce this error?
Remark: To my knowledge, user B has never used the computer of user A and therefore should also never have entered his password on this computer.
How can we find out what happened and how we can avoid it?
Did anyone else here have a smiliar problem?
