[Dovecot] My "%%" variables in the namespace settings do not appear to be expanding.
Hello,
I've been using the dovecot 1.2.x branch server software for a
while now. With the advent of the 2.0.x branch going 'stable' I
decided to attempt a migration and make use of some of the features
that I've not needed before. One of these is the shared
folder/namespace feature. No luck. I've hit a wall and can not
determine the problem. At the moment it looks like a bug to me,
but it may well be that I'm missing some related configuration, or
file permission.
I can not get the %% variable expansion in a namespace to work.
What I end up with, on an IMAP connection is a directory named, for
instance, '%h'. The same goes for any of the %% variables used at
this point. My current set-up is 'not' the same as the current
setup and I'm using virtual users that are not 'live' on the
current system.
I would really appreciate it if someone could cast an eye over my
config and let me know if I've missed something obvious.
Thanks.
Kenneth Cope

Set mail_debug=yes. What does it log when 1) logging in and 2) when it creates the %% directory (or is that also on login)?
namespace { list = children location = maildir:%%h:LAYOUT=maildir++:INDEX=~/shared.%Dn_%Dd prefix = shared/%n@%d.
prefix = shared.%u.
Although this won't work well because your username most likely has '.' characters. The only good solution would be to change all separators to '/', but that can then cause problems with existing clients that use your system (possibly requiring some kind of client cache refresh / account recreation).
Hi Timo,
Thank you for the response.
I've attached the output for the login connections. The SSL lines
have been stripped as that is not properly set up yet.
This log is with the change suggested (prefix = shared.%u.),
although I can't tell any different in the log entries not in the
results.
Just to clarify, the directory that gets created is named "%h".Kenneth

This is ok.
namespace { hidden = yes inbox = no list = no location = prefix = INBOX separator = . type = private }
This doesn't much make sense and I doubt Dovecot actually uses it for anything. Just remove it.
namespace { list = children location = maildir:%%h:LAYOUT=maildir++:INDEX=~/shared.%Dn_%Dd prefix = shared/%n@%d.
I forgot, prefix here should contain %%u, not %u, because %u gets expanded to your own username while you want it to be expanding to other users' username.. I'll add a check against this.

Unfortunately, I can't use %%u variable as is. The usernames
contain the dot character. That's essentially why I was using the
%Dn_%Dd construct. I can't find a way of doing this type os
escaping/modifying for the %% variables.
%%Dn, for example, gives:Sep 02 16:26:01 auth: Debug: passwd-file(@23foxgrove.co.uk): lookup: user=@23foxgrove.co.uk file=/usr/local/dovecot-2.0.1/auth/passwd.dovecot
%D%n, does not work, understandably, and caused a LOT of error
messages and stops the server being usable.
I was originally hoping for a modifier for the dot character in
variables, in the same way that the quote characters can be escaped
with the %E prefix modifier.
I'm pretty sure that I can't change the separator to a '/' as there
is a large installed user base and we'd prefer this to be as
transparent as possible.
All this help is appreciated.Kenneth Cope.

Use %%Dn and %%Dd

Hmmh.

Oops, you mentioned %%Dn. Yeah .. looks like there are some problems using modifiers there. Should be possible to get that fixed..

Now I remember. It of course needs to be able to reverse the %%Dn_%%Dd when parsing it back to user@domain, and no such code exists (and I'm not all that interested in adding such code).
Maybe one potential way to solve this would be to create user aliases that don't have any dots in the usernames and do the sharing via those names.

Fair enough, I don't blame you.

It may be that I'm leading this down a track because I've already tried to sort this out and gone about it the wrong way.
Essentially I have users with a dot in the name, with a namespace separator that is set to be a dot character also, and I'd like a configuration that lets them have shared folders via IMAP ACLs. Is there a configuration that will allow this with the current dovecot?

No. That would require changing the dots to something else and back in several places in the code. Maybe this could be done automatically some day..
