These can be replaced with global settings:

mail_uid = vmail
mail_gid = vmail
mail_home = /var/maildir/%u

Just set those global settings and drop uid/gid/home from here. Or you
could get them working here too, but the syntax is slightly wrong:

user_attrs = =uid=vmail, =gid=vmail, ..

(With the above settings you're telling Dovecot that LDAP "uid" field
will be assigned to Dovecot's "vmail" field, and the "gid" field
immediately overrides it, and LDAP "home" field's value is set to
Dovecot's "/var/maildir/%u" field.)
