You could use
passdb { driver = ldap args = /path/to/dovecot-auth-ldap.conf.ext }
passdb { driver = passwd skip = authenticated }
instead. then you can map quota stuff for your LDAP users and not for the passwd users.

Hi, thanks for your helpful reply.
I understand that default_fields is not my solution.
To be more accurate, all users in ldap db need to use mail, but some users in /etc/passwd file use mail too. For this reason I set up "driver=passwd" in userdb section and in /etc/nsswitch.conf I set up "passwd: files ldap". Now I want to use dovecot per user quota to limit ldap users mailbox size. I need quota only for ldap users, no need for users in /etc/passwd file.
Which is the correct configuration to do this? I understand that I need to use extra fields to obtain user quota from users db. But you said "the userdb section cannot merge two databases together". So I can not use dovecot per user quota with "driver=passwd" in userdb section? I could use only global quota?
Thanks in advance

P.S.
I use dovecot-lda as delivery agent.
I send again my dovecot configuration:

I have problems in return extra fields from passwd userdb. My users are partially in passwd files and partially in LDAP. Users who use mail are in LDAP db.
If I use "default_fields = quota_rule=*:bytes=100M" in userdb,
if I use "default_fields = quota_rule=*:bytes=%{userdb:quotabytes}" in userdb,
default_fields supplies default values, if the userdb does not return them. Hence, you cannot reference a LDAP result.
the userdb section cannot merge two databases together. You said "Users who use mail are in LDAP db", so you would one userdb with driver ldap.
