The URL on the wiki, which had probably been shared before with you;

suggests it does.

The URL quotes:

Step 5. Passwordless authentication

If you have logged on from Windows to the AD domain, try leaving the password field, on the account, on the MUA, blank. The username / password, from the initial logon to the Windows machine, are seamlessly picked up and supplied to the challenge-response process between the MUA, Dovecot and AD. Employing this way of authentication  we achieve single sign-on and we don't need to maintain MUA local passwords.

Did you follow the suggestions that are on that page? (all of them).

Thank you,
