Hello,

I'm trying to set up LDAP stored quota on Dovecot but it doesn't work and doesn't get reported by the command doveadm quota get.

I'm using the field departmentNumber in my LDAP server to store the quota.

doveadm quota get -u test

Quota name Type    Value Limit                                                                                %
User quota STORAGE     0     -                                                                                0
User quota MESSAGE     0     -                                                                                0

log file associated with doveadm quota get command:

Nov 21 11:38:47 imap dovecot: auth: Debug: master in: USER#0111#011test#011service=doveadm
Nov 21 11:38:47 imap dovecot: auth: Debug: ldap(test): user search: base=ou=People,dc=example,dc=com scope=subtree filter=(&(objectClass=posixAccount)(uid=test)) fields=departmentNumber
Nov 21 11:38:47 imap dovecot: auth: Debug: ldap(test): result: departmentNumber=1M; departmentNumber unused

Bellow my configuration files:

conf.d/10-mail.conf

mail_plugins =  $mail_plugins quota

conf.d/20-imap.conf

protocol imap {
  mail_plugins = $mail_plugins imap_quota
}

conf.d/90-quota.conf

plugin {

  quota = maildir:User quota
  quota_rule2 = Trash:storage=+100M
  quota_grace = 10%%
  quota_status_success = DUNNO
  quota_status_nouser = DUNNO
  quota_status_overquota = "552 5.2.2 Mailbox is full"

}

dovecot-ldap.conf.ext

user_attrs= \
=mailRoutingAddress=user \
=uid=vmail \
=gid=mail \
=home=/var/mail/%d/%n \
=quota_rule=*:bytes=%{ldap:departmentNumber}

Can somebody help me with this or give me some advice for debugging?
