I don't know the exact details of the antispam configuration. But I have asked and the administrator told me that we are not doing ARC tests.

I don't find any good guide and everything I have found is some years old. Has any of you done a recent integration with CAS and can share the details ? I can't help you with rouncube part (because we use horde as webmail), but dovecot we have configured with pam_cas module. The idea is that horde pass a PGT as user password, and with PAM dovecot server checks it. -- Angel L.

Re: Exclude userdb from iterate users
I'm trying to configure an iterate_filter returning an empty result. So
I have configured:
iterate_filter = (objectClass=objectClassNoExiste)
My question is, why I'm having this log in ldap?
Oct 25 12:46:41 canis30 slapd[25736]: conn=1192459 op=1 SRCH
base="ou=Correo,ou=Groups,dc=Telematica" scope=2 deref=0
filter="(?objectClass=objectClassNoExiste)"
It is adding a question mark ("?" char) at the beginning of the search.
The problem is that sometimes dovecot auth is crashing with:
Oct 25 12:57:13 myotisfa61 dovecot: auth-worker(24036): Debug: ldap:

Hi,
I have a system with various userdbs defined, mostly all of them
based on ldap (and a few passwd-files).
I want one of my ldap userdbs not to be used in "doveadm user -A"
commands, that is to be excluded in iterate searchs. I have no
iterate_filter neither iterate_attrs configured in that userdb, but it
is still used.
Is it possible? How?

I'm trying this. In the ldap configuration, I have:
pass_attrs =
=userdb_user=%{ldap:mail},=userdb_quota_rule=%{ldap:quota:*:storage=10G},=userdb_uuid=%{ldap:entryUUID}
user_attrs =
=user=%{ldap:mail},=quota_rule=%{ldap:quota:*:storage=10G},=uuid=%{ldap:entryUUID}
and in my dovecot config I get:
mail_home =/mail/mailboxes/%L{uuid}
but when I get user fields I have:
field value
uid vmail
gid vmail
home/mail/mailboxes/unsupported_variable_uuid
mailmdbox:~/mdbox:INDEX=/mail/indexes/um.es/an/angel.luis
quota_rule *:storage=10G
uuiddc6c5cd6-bf4d-1030-8d28-d5b8647941b3
it seems I can't use this "uuid" variable in mail_home config.
Is it possible? Am I doing something wrong?
