[Dovecot] dovecot-pgsql.conf can't find in chroot? (debian)

6 Mar 2005


      In my original email I noted that the directory /usr/local/etc was in
the dovecot.conf variable valid_chroot_dirs :
valid_chroot_dirs = /usr/local/etc:/etc:/var/mail:/lib
Is that not sufficient?  Under the /var/run/dovecot directory the
directories ./usr/local/etc exist with dovecot-pgsql.conf in.
Is there some big RTFM item I'm missing here?

P.S. - email address changed due to problems with upstream, will jump
back as soon as this is fixed so I can finish my migration :)

The file exists, and permissions look good:

...let me guess, you're not in the chroot here?
So, how should dovecot be able to find this file while it runs chrooted?
You need to put all needed files into the chroot.

Yep, that's how it's with 0.99.x. With 1.0-tests however Dovecot opens
the dovecot-pgsql.conf before chrooting.

Plagued with an error I can't get past:

I have dovecot (+ssl) configured on debian in a chroot with
postfix+pgsql+sasl.
The file exists, and permissions look good:
root at alfa:~# ls -la /usr/local/etc/dovecot-pgsql.conf
lrwxrwxrwx  1 root dovecot 31 2005-03-04 20:35

-rw-r--r--  1 root dovecot 2875 2005-03-01 23:38
/etc/dovecot/dovecot-pgsql.conf
But... dovecot-auth can't see it?  That's weird...

Excerpts from /etc/dovecot/dovecot.conf:
auth_userdb = pgsql /usr/local/etc/dovecot-pgsql.conf

login_chroot = yes

Any recommended next steps?
Thanks a million!
