Hi,

I am trying to enable per user quotas, but I get the following error:

Feb 18 23:59:20 vmail dovecot: auth(default): 

ldap(tester,10.10.100.150): ldap_search((uid=tester)) failed: No such object

It seems as if ldapsearch for username/password won't work with my new settings, but I can't find why.

I run Dovecot v1.2.11 on CentOS 5.5.

I changed my working dovecot.conf (see later) with the following changes (I used the roomNumber attribute to store the quota value):

1. Added in main part:

   mail_uid = 500 mail_gid = 500

2. Changed userdb with:

   userdb ldap { args = /etc/dovecot-usrdb-ldap.conf }

   and /etc/dovecot-usrdb-ldap.conf is:

   hosts = localhost tls = no base = ou=people, dc=example, dc=com scope = subtree ldap_version = 3 auth_bind = yes user_filter = (uid=%u) pass_filter = (uid=%u) pass_attrs = uid=user,userPassword=password auth_bind_userdn = uid=%u,ou=people,dc=example,dc=com user_attrs = roomNumber=quota_rule=*:bytes=%$,uid=home=/home/vmail/%u

3. Changed passdb with

   passdb ldap { args = /etc/dovecot-passdb-ldap.conf }

where /etc/dovecot-passdb-ldap.conf is identical to dovecot-usrdb-ldap.conf.

What am I doing wrong? Please advise.

Thanks in advance, Nick

My working dovecot.conf is:

 and dovecot-ldap.conf is:
