set static group and user for every mailbox

[edoput]

This should solve the issue with multiple maildirs

It doesn't work.
From /var/log/mail.log:

Jun 8 23:28:27 mail dovecot: lda(test_user@lilik.it): Fatal: setgid(100(users) from userdb lookup) failed with euid=800(postman), gid=800(postman), egid=800(postman): Operation not permitted (This binary should probably be called with process group set to 100(users) instead of 800(postman))

Override an entire file (/etc/dovecot/dovecot.conf) only to add two lines is not a good practice, since it cause the loss of all the configuration change from the package maintainers.

homeDirectory and vdhome are either ldap attributes and none of them is a valid dovecot userdb attribute.

If this line is only a trick to disable default users_attrs query I suggest something more self explaining.

Funny fact
this query works fine too (tested!)

users_attrs = pippo=pippopippo #(I hope you enjoy the reference)

[edoput]

user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid
# or if you're using global UID and GID:
user_attrs = homeDirectory=home

that was on the ldap configuration on the wiki, guess it's outdated too.

Why aren't we using a static userdb? It seems that it's the best choice

Since dovecot-lda looks up the user only from the userdb, it of course doesn't work with static userdb because there is no list of users. Normally static userdb handles this by doing a passdb lookup instead. This works with most passdbs...

We could get rid of this insane back and forth with LDAP users database
