I finally managed to get this going but I have noticed in my case that:
- I need to make sure the user logon name in AD and the samAccountname are exactly the same, case and all. It seems postfix uses the samAccountname and Dovecot the User logon name.
- I also noticed that if the Display name for a user in AD is blank, that user cannot log in using telnet <server ip> 110.
I am quite willing to work with it as it is but if anyone knows if this is normal behavior or not, I would be glad to know. Not sure if some could be configured better.
Just for information, I am including my current configs. Thanks for your assistance Steffen.

The command doveadm user -u username successfully returns the username and
any information it can for the user in AD. As a matter of fact, I entered some home directory information in AD and this command returned the User's Home Directory as well. Is it a problem though that the telnet test won't work?
Hmm, I don't understand the question,
telnet xyz 143 1 login username password
must work in order to login via IMAP.
But you didn't answered the other question, see below

^^^^^^^ that same as the username in doveadm?Here. You've posted mangled information only, so if the extra fields return another username, other tests are different.
What about:
doveadm user -u username
?
When I tried to log in again using telnet 127.0.0.1 110, the error shows up
in maillog. I first tried logging in with just the username, then I tried using username@domain.com. Using doveadm still works though.
