Hi all again, I've just realized that I did a bad cut&paste in my previous mail, then I rewrite my request. I apologize.

I am trying to set up my dovecot configuration using LDAP and virtual mailboxes. I succeeded in authenticating the users correctly with LDAP, but have problems with referencing the correct mail location directory. I manage several domains. The mailboxes are stored under separate directories for each domain:

/mail/vmail/domains/writers.com/William.Shakespeare/ /mail/vmail/domains/writers.com/Jack.London/

/mail/vmail/domains/painters.com/Pablo.Picasso/ /mail/vmail/domains/painters.com/Vincent.VanGogh/

Now, I supposed I could build the path by setting the common part of the paths as mail_location into dovecot.conf:

mail_location = maildir:/mail/vmail/domains/%h passdb ldap { args = /etc/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot-ldap.conf } userdb prefetch { }

and getting the variable part ("domain/user", i.e. writers.com/Jack.London) from the userdb in dovecot-ldap.conf:

auth_bind = yes auth_bind_userdn = mail=%u,vd=%d,o=hosting,dc=example,dc=com ldap_version = 3 base = o=hosting,dc=example,dc=com deref = never scope = subtree user_attrs = mail,,mailbox,mail,, user_filter = (&(objectClass=VirtualMailAccount)(accountActive=TRUE)(mail=%u)) pass_attrs = mail=user,userPassword=password,mailbox=userdb_home,mail=userdb_uid,mail =userdb_mail pass_filter = (&(objectClass=VirtualMailAccount)(accountActive=TRUE)(mail=%u)) default_pass_scheme = CRYPT

In the LDAP database the fields are something like:

mail = Jack.London@writers.com mailbox = writers.com/Jack.London uid = Jack.London

However, the above does not work. Here is an extract from the log:

Oct 16 15:57:07 mymail.example.com dovecot: auth(default): ldap(Jack.London@writers.com,::ffff:127.0.0.1): user search: base=o=hosting,dc=example,dc=com scope=subtree filter=(&(objectClass=VirtualMailAccount)(accountActive=TRUE)(mail=Jack.London@writers.com))

fields=mail,mailbox,mail Oct 16 15:57:07 mymail.example.com dovecot: IMAP(Jack.London@writers.com): Ambiguous mail location setting, don't know what to do with it: writers.com/Jack.London/ (try prefixing it with mbox: or maildir:) Oct 16 15:57:07 mymail.example.com dovecot: IMAP(Jack.London@writers.com): Failed to create storage with data: writers.com/Jack.London

Any hints? BTW, I am trying to prefetch, as you see, but I am not sure that works too. Thanks in advance
