Auto-Fill Changes to an Incorrect Email Address

Auto-fill changes to an incorrect email address (typically the Administrators)

When using Safari during administration setup,  when editing a users email address or Federation ID, the Safari Autofill will change the field to your own email address (the administrators).  This makes it so you have to re-enter the information in the email or federation field.  This actually happens due to the Auto-Fill feature in Safari.  To change this setting do the following:
In Safari there is a setting called Auto-Fill, this should be disabled.
Safari > Preferences > AutoFill tab -- uncheck User Names and Passwords 

The downside to this is, if you want Safari to remember and fill out your Workfront Login username and password, it will no longer do this.
