Re: [Dovecot] problems with folders in another server (2nd. issue)

[Jose Luis Faria]

Hello Timo,

I'm using qmail-LDAP in cluster with 2 servers:

mx1.di.uminho.pt and mx2.di.uminho.pt

the email cx1 is on mx1 and I want to get access using both servers.

dovecot-ldap.conf.ext:
...
pass_attrs = uid=user,userPassword=password,=y=proxy_maybe,mailHost=host
...

every user on LDAP have the attribute

mailHost=mx1.di.uminho.pt

or

mailHost=mx2.di.uminho.pt

we are using two servers, with dovecot 2.0.5, Sx and Sy,
with:

cat dovecot-ldap-ext:

...


When I access server Sx via IMAP I see all my folders.
When I access server Sy via IMAP it do not proxy to Sx.

It doesn't look like it's even trying to proxy. Otherwise your login to
Sx would fail with "Proxying loops to itself" error. So..

1) Change =y=proxy to =y=proxy_maybe

2) Show your doveconf -n output

3) Set auth_debug=yes and show the logs when logging in to Sy.
