since upgrading to iOS9 my icloud account is messed up.

[iMore Question]

It has signed my student in to icloud with an accout he doesn't have. It is not his apple id that is signed into icloud. It doesn't let me sign him out of the account currently on icloud because we do not know the password. I have had several students with this issue since updating. Any suggestions on how to get this icloud i.d. off and get their apple i.d.s back?

Log out of iCloud on all the devices and log in with correct AppleID and password.
