dovecot - Feb 2006 - Outlook anonymous IMAP login

Hello guys,

I'm trying to setup anonymous IMAP login on a bunch of Outlook clients,
but it doesn't seems to work.

I'm using dovecot-0.99.14-r1, on a Gentoo Linux OS. 

Using command line anonymous login, it's working just fine:

youri / # telnet localhost 143
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
* OK dovecot ready.
. CAPABILITY
* CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT
LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED NAMESPACE STARTTLS
AUTH=PLAIN AUTH=ANONYMOUS
. OK Capability completed.
. AUTHENTICATE ANONYMOUS
+

. OK Logged in.

But with Outlook it's not working at all. I tried using no password, or
just some random stream, it makes no difference.

The error I got in dovecot's logs are:
Feb 07 12:31:16 Info: PAM: pam_authenticate(anonymous) failed:
Authentication failure
Feb 07 12:31:19 Info: PAM: pam_authenticate(anonymous) failed:
Authentication failure
Feb 07 12:31:28 Info: PAM: pam_authenticate(anonymous) failed:
Authentication failure

My assumption is that Outlook doesn't provide anonymous IMAP support.
Could someone confirm this ? Do you know if any workaround/anonymous
plugin exist ?

Thanks !

That's right. Most IMAP clients don't since it's so rarely used.

You could create anonymous user with empty password, which would then be
used.

If you upgraded to 1.0beta, you could do this:

passdb passwd-file {
  args = /etc/anon.passwd
}
passdb pam {
}
userdb passwd-file {
  args = /etc/anon.passwd
}
userdb passwd {
}

Where /etc/anon.passwd contains something like:

anonymous:{PLAIN}:1000:1000:,,,:/home/anonymous:/bin/false
