Hi,

I have noticed that during auth cache hits usernames are not updated. (We use ldap backend and change username with user_attrs = uid=user, mailMessageStore=home, mailQuotaSize=quota_rule=*:bytes=%$

cold cache

lmtp(14414): Debug: auth input: testmon_testmon home=/vmail/te/testmon_testmon quota_rule=*:bytes=104857600 lmtp(14414): Debug: changed username to testmon_testmon lmtp(14414): Debug: Added userdb setting: plugin/quota_rule=*:bytes=104857600

hot cache

lmtp(14715): Debug: auth input: iqmon@mon.test.pl home=/vmail/iq/testmon_testmon quota_rule=*:bytes=104857600 lmtp(14715): Debug: Added userdb setting: plugin/quota_rule=*:bytes=104857600

auth replays are

USER\t2\ttestmon_testmon\thome=/vmail/te/testmon_testmon\tquota_rule=*:bytes=104857600\n on a cache miss

and

USER\t3\ttestmon@mon.test.pl\thome=/vmail/te/testmon_testmon\tquota_rule=*:bytes=104857600\n with a cache hit

without cache user is rewriten as expected, with cache it isn't

requests made by imap or pop3 are always rewriting the usernames

is it a bug or is it intentional ?

this kills our dictionary based quota (users have multiple quota instances depending on timing and alias the email was delivered to.

Is there a way to force addition of user to the auth cache ?

Did you posted your doveconf -n and ldap settings somewhere?

I have atached a dirty hack that fixes the issue for me (username changes are cached in userdb auth cache).

config follows

dovecot -n

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

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

dovecot-ldap.conf.ext

debug_level = 32 auth_bind = no ldap_version = 3 base = ou=accounts,o=test,c=pl

user_attrs = uid=user, mailMessageStore=home, mailQuotaSize=quota_rule=*:bytes=%$ user_filter = (&(&(!(accountStatus=deleted))(objectClass=qMailUser))(|(mail=%u)(uid=%u)(mailAlternateAddress=%u)))

pass_attrs = uid=user, userPassword=password pass_filter = (&(objectClass=qMailUser)(|(mail=%u)(uid=%u)(mailAlternateAddress=%u)))

iterate_attrs = uid=user iterate_filter = (&(&(objectClass=qmailUser)(!(accountStatus=deleted))))

full doveconf -n
