Hi Daniel,

The "userdb" ldap is in this section:

protocol lmtp { mail_plugins = " quota sieve" userdb { args = /etc/dovecot/dovecot-ldap-lmtp.conf.ext driver = ldap } }

And dovecot-ldap-lmtp.conf.ex contains this:

hosts = xxx.xxx.es:389 dn = uid=xxxxx,o=xxxxxx,c=es dnpass = xxxxxxxxxxx ldap_version = 3 base = o=xxxxxxxxxxxx,c=ES user_attrs = mailMessageStore=home,mailquotasize=quota_rule=*:bytes=%$ user_filter = (uid=%u)

Hi Raul,

We get user's quota limit from LDAP.  It works fine when user has quota attribute in LDAP (this is when it's different from default quota). But when user doesn't have quota limit attribute Dovecot doesn't take default value defined in quota plugin and assign unlimit quota to user.

Our configuration is similar to the example from wiki ( http://wiki2.dovecot.org/Quota/Configuration ). This is the plugin configuration

plugin { quota = maildir:User quota quota_rule = *:storage=1G }

And this is the recovered fields in LDAP search:

user_attrs = > mailMessageStore=home,mailquotasize=quota_rule=*:bytes=%$

It works if user has mailquotasize in its LDAP entry. But if it hasn't it Dovecot assign 0 instead of  *:STORAGE=1G

This is the log when LTMP deliver a mail to a user without mailquotasize attribute:

_auth: Debug: ldap(eepp68,172.31.100.119): result: mailMessageStore=/buzones1/e/eepp68; MAILQUOTASIZE MISSING

LDAP Entry for mailquotasize is missing... so far so good.

auth: Debug: master out: USER#0111#011eepp68#011home=/buzones1/e/eepp68#011QUOTA_RULE=*:BYTES= lmtp(8235): Debug: auth input: eepp68 home=/buzones1/e/eepp68 quota_rule=*:bytes= lmtp(8235): Debug: Added userdb setting: plugin/quota_rule=*:bytes=

Here comes the interesting part, ldap "userdb" has returned "QUOTA_RULE=*:BYTES=" and this empty value seems to correspond to 0 Bytes as you can read from the resulting Quota rule:

lmtp(8235, eepp68): Debug: Quota rule: root=User quota mailbox=* bytes=0 messages=0

The "bytes=..." value should be different from 0.

http://wiki2.dovecot.org/Quota/Configuration#LDAP states that user_attrs is used only if you use userdb ldap.

Where is the "userdb" ldap in your doveconf -n output and where do you get the user information like quota from?

Any idea about where is the problem?

The default is not taken since your LDAP query returns a quota_rule with an empty bytes= value when the mailquotasize entry is missing.
