I'll admit I don't understand what you're trying to do with the above 
parameters, but let me share what I'm using and see if it helps.  I 
happen to be using a pure virtual configuration, with my mail users 
logging in using their full email address as a username.  So all I need 
to store in LDAP is the email address and the password.

dovecot-ldap.conf
user_attrs = maildir:%d/%n/Maildir=mail,%d/%n=home
pass_attrs = mail=user,userPassword=password

dovecot.conf
[...]
mail_location = maildir:/var/mail/%d/%n/Maildir
[...]
userdb static {
  args = uid=vmail gid=vmail home=/var/mail/%d/%n 
mail=maildir:/var/mail/%d/%n allow_all_users=yes
}
[...]

This lets me store all mail under /var/mail/DOMAIN/USER/Maildir - with a 
home of /var/mail/DOMAIN/USER.

I'm pretty sure at least some of the parameters I'm using are redundant 
or unused, but thus far it works great.
