Return extra fields from passwd userdb

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,

Output of "doveadm -D quota get -u afasystems" is:

1) default_fields supplies default values, if the userdb does not return 
them. Hence, you cannot reference a LDAP result.

2) 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.

Return extra fields from passwd userdb

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

Michele

P.S.
1) I use dovecot-lda as delivery agent.

2) I send again my dovecot configuration:
