Is it possible to have local users with mail in maildir:%h/.maildir

and virutal users with mail in maildir:/home/exim/%u/.maildir

I seem to have authentication working for both local users and LDAP users. But I'm getting this error trying to access a virtual users mail.

Per your previous message, your LDAP server is down. Dovecot can't communicate with it.

LDAP isn't returning home. You'll need to return it in user_attrs in dovecot-ldap.conf.

Or .. Well, two choices:

a) return /home/exim/user as home directory from LDAP

b) return mail=maildir:/home/exim/user/.maildir from LDAP.

You can't set multiple default_mail_env settings currently, so the home must come from LDAP. Or I suppose alternatively you could use static instead of LDAP as userdb if all your virtual users use the same UID.

Thank you Timo,

I changed default_mail_env = maildir:/home/exim/%n/.maildir

I may not have to support local users

But I'm still running into the problem that the user authenticates as Firstname Lastname which is the cn in LDAP but the uid in LDAP, which would be something like flastname needs to be used for mail location.

Is there a way to use the uid in LDAP to specify the mail location, without modifying the current LDAP database to include the full path?

It would have been easier to answer if you had given your dovecot-ldap.conf settings. But if "uid" in LDAP contains the short form, then giving pass_attrs = uid=user,.. should help. Although that was also there by default..

I've gone with option a) in order to proceed with testing. I am going to need local and virtual users with independent mail_env. How feasible would it be to allow dovecot to override default_mail_env on a per userdb basis?

A static won't work in my case since the maildir path is derived from info in LDAP. I also haven't been able to get dovecot to use the uid from LDAP for %u or %n as apposed to the cn which is what is used for authentication.

The good news is that so far the testing of performance looks promising relative to the courier-imap we've been using :)
