"Login failed" with new email accounts

[beatnik]

I moved from RC 0.1.x to 0.2.2 in late May.  I installed the new version into a new folder (I did not overwrite the old set of files).  Existing users have had no problems logging in; but two new email accounts (added using my ISP's CPanel application) have login problems.
Specifically, I am told "Login failed" when I attempt to login.

Coincidentally, I still have a copy of Ilohamail, the webmail program I used before RoundCube, and I am able to login to these two new accounts via Ilohamail.  According to all the information I have from my ISP, the accounts created are IMAP accounts, and since I've not had problems before, I don't think this is the issue.

Any ideas?  I am baffled!

check what the value of $rcmail_config['auto_create_user'] is in your config.

It was set to FALSE.  I changed it to TRUE and everything works fine, now.  Thank you so much!
