Error when changing user name in Apigee <p>I have a space in the user name in my organization's Apigee account. I use the User Settings page to attempt to update the user name by deleting the space and keeping only the alphabet characters, but I keep getting the error "Username should contain only alphanumerals, dot, dash and underscore. Please try again." This has to be a bug in the Apigee UI. How else can one change the user name?</p>
