Hello everybody!
I am trying to build a cyrus murder with virtual hosting enabled. In the
future we will probably have two or three frontends on round robin dns, so
I have imapd:s running on an IP-aliased interface. This works fine, let's
call it foo.abo.fi.
Now, on the same frontend I need another set of imapd:s which run on yet
another IP-alised interface, which has a DNS-entry on another domain,
say bar.baz.org. The reasons for doing this is:
- they want "their" imap-server on their own domain
- they want to log in as "username", not "username@domain"
- they want to authenticate to their active directory (through
saslauthd-krb5, all other virtual domains use mysql auxprop)
Now, if I create a mailbox "testuser@xxxxxxx" and log in as
testuser@xxxxxxx everything works as it should:
> telnet foo.abo.fi imap
* OK foo.abo.fi Cyrus IMAP4 Murder v2.2.12-AAU-RPM-2.2.12-3.RHEL4.1.aau server ready
1 LOGIN testuser@xxxxxxx ********
1 OK User logged in
2 LIST "" *
* LIST (\Noinferiors) "." "INBOX"
2 OK Completed
3 SELECT INBOX
* FLAGS (\Answered \Flagged \Draft \Deleted \Seen)
* OK [PERMANENTFLAGS (\Answered \Flagged \Draft \Deleted \Seen \*)]
* 3 EXISTS
* 1 RECENT
* OK [UNSEEN 3]
* OK [UIDVALIDITY 1160720446]
* OK [UIDNEXT 4]
3 OK [READ-WRITE] Completed
4 LOGOUT
* BYE LOGOUT received
4 OK Completed
But if I try to use the server on bar.baz.org, the LIST command fails to
retrieve any mailboxes:
> telnet bar.baz.org imap
* OK foo.abo.fi Cyrus IMAP4 Murder v2.2.12-AAU-RPM-2.2.12-3.RHEL4.1.aau server ready
1 LOGIN testuser@xxxxxxx ********
1 OK User logged in
2 LIST "" *
2 OK Completed
3 SELECT INBOX
3 NO Mailbox does not exist
4 LOGOUT
* BYE LOGOUT received
4 OK Completed
The same thing happens when I omit the @baz.org part:
> telnet bar.baz.org imap
* OK foo.abo.fi Cyrus IMAP4 Murder v2.2.12-AAU-RPM-2.2.12-3.RHEL4.1.aau server ready
1 LOGIN testuser ********
1 OK User logged in
2 LIST "" *
2 OK Completed
3 SELECT INBOX
3 NO Mailbox does not exist
4 LOGOUT
* BYE LOGOUT received
4 OK Completed
If I dump the contents of mailboxes.db I get the correct results on all
machines in the murder.
Ok, then some snippets from the config files:
bar.baz.org-imapd.conf:
configdirectory: /var/imap
sievedir: /var/sieve
defaultpartition: virtual
partition-virtual: /var/spool/virtual
hashimapspool: false
unixhierarchysep: no
altnamespace: yes
sharedprefix: shared
singleinstancestore: yes
duplicatesuppression: yes
allowusermoves: yes
servername: bar.baz.org
virtdomains: on
loginrealms: baz.org
defaultdomain: baz.org
sasl_pwcheck_method: saslauthd
(... + other SASL, lmtp, tls and mupdate stuff)
The working server foo.abo.fi has the same config, except for:
servername: foo.abo.fi
loginrealms: xxx yyy zzz abo.fi
defaultdomain: abo.fi
sasl_pwcheck_method: auxprop
I get the same result when using "virtdomains userid". I tried to mix the
forms but that didn't work at all (but there could have been other reasons
as well.)
Any ideas? It seems like the fact that the virtual server is on another
network (in DNS, not physically) somehow screws up the mailbox lookups
from mailboxes.db. (I've run several instances of imapd:s on other servers
with different configs, though not with virtual domains on, and I think
other people use it as well.) This should be possible to do, right? There
are no complaints in the logs.
cyrus.conf:
SERVICES {
mupdate cmd="/usr/lib64/cyrus-imapd/mupdate" listen=3905 prefork=1
imap cmd="/usr/lib64/cyrus-imapd/proxyd -C /etc/imapd-foo.conf" listen="foo.abo.fi:imap" prefork=0
imaps cmd="/usr/lib64/cyrus-imapd/proxyd -s -C /etc/imapd-foo.conf" listen="foo.abo.fi:imaps" prefork=0
himap cmd="/usr/lib64/cyrus-imapd/proxyd -C /etc/imapd-baz.org.conf" listen="bar.baz.org:imap" prefork=0
himaps cmd="/usr/lib64/cyrus-imapd/proxyd -s -C /etc/imapd-baz.org.conf" listen="bar.baz.org:imaps" prefork=0
}
I use the RHEL4-supplied x86_64 packages, though recompiled to disable the
autocreate patches.
