You don't authenticate with Dovecot via an alias. You need to

authenticate with the actual username.

<br />To add to what Michael said - you also don't authenticate with any combinations of uppercase/lowercase. The reason the system coughed when you put in JohnDoe for the username - the username must be all lowercase.
<br />
<br />So you create the user "johndoe". That account will automatically accept e-mail for "johndoe", "JohnDoe", "JOHNDOE", "JoHnDoE" or any other combination of upper/lower as long as they spell out "johndoe". But no matter what email address the user wants to use - he MUST log in with the all lowercase "johndoe" username. Anything else (including any capitals at all) will fail authentication.
<br />
<br />And to expand on what Michael mentioned - creating the alias "JD@" for that user account "johndoe" does not mean he can log in with "JD". Its just a e-mail alias - login is still the username "johndoe" all in lower case.
