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:

Return extra fields from passwd userdb

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.

Does users exist in both passwd and ldap?

If you did this for Dovecot, revert it.

use two databases for both passdb and userdb. One using pam / passwd, the 
other one the standard LDAP config.

see: 
https://wiki2.dovecot.org/Authentication/MultipleDatabases

Use LDAP instead of SQL userdb and passdb.

I guess, you will find posts in the sense "virtual and system users".

If there is no user in both databases, the order does not matter (except 
for speed); otherwise:

each database is tried in order of definition until a successful hit was 
found.

You can order the passdb's and userdb's differently, e.g. if
passwd-passdb
is first and the user's password match, and the ldap-userdb is first and 
you get a hit there, the user authentificates against passwd, but its data 
is retrieved from LDAP.
See comment in page: "look up users from SQL first (even if authentication 
was done using PAM!)"

You cannot merge, but use one-after-another.
