[Dovecot] Marathon Day 6 of First Install: MySQL Connection Problem

This is my 6th day installing my first Postfix/Dovecot installation. The Postfix mailing list indicates I've got the MTA under control so now I'm seeking your help with the MDA. I get these errors with legitimate email addresses:
Oct 24 11:47:38 myserver dovecot: auth-worker: Error: mysql(localhost): Connect failed to database (postfix): Access denied for user 'dovecot'@'localhost' (using password: YES) - waiting for 25 seconds before retry

Now I've logged in myself:
mysql -u dovecot -p
Enter password: xxx
and succeeded. What am I doing wrong?

I've noticed that every time I restart dovecot I get this error in the dovecot-deliver.log:

Oct 24 11:31:11 lda: Error: userdb lookup: connect(/usr/local/var/run/dovecot/auth-userdb) failed: Permission denied (euid=512(vmail) egid=512(vmail) missing +r perm: /usr/local/var/run/dovecot/auth-userdb, dir owned by 0:0 mode=0755)
Oct 24 11:31:11 lda: Fatal: Internal error occurred. Refer to server log for more information.

Every time I go to chmod 666 on that file, restarting dovecot wipes those permissions. How fix?
Even when I fix that, I still get the "temporary failure".
Please advise.
