When importing existing users using the user excel import, a checkbox lets the user manager decide how to deal with those existing users. The default is to overwrite the profile data with the data from the excel file and to not update the passwords.
This is somewhat inconsistent and can lead to accidental profile overwrites in case of users who do not read the dialog carefully and just press next. Thus, the new default is set to not touch existing users at all.
The dialog is adjusted to display a more colorful message to make the user aware that he must make a decision how to proceed with existing user data.
