I set up imapd.conf how I think it should be and restarted cyrus (even
rebooted hosts). I log into the source server cyradm:
sudo cyradm --user cyrus --server server1.sub1.domain.amazon.com --auth
plain
Run the xfer
server1.sub1.domain.com> xfer user.vbperry server2.sub2.domain.com
And get:
xfermailbox: Server(s) unavailable to complete operation
This is in log on source:
Apr 14 15:08:15 server1 imap[3434]: couldn't authenticate to backend server:
generic failure
Apr 14 15:08:15 server1 imap[3434]: Could not move mailbox: user.vbperry,
Initial backend connect failed
This is on destination server:
Apr 14 15:08:15 server2 imap[3022]: accepted connection
Apr 14 15:08:15 server2 master[3125]: about to exec
/opt/mail/cyrus-imapd/bin/imapd
Apr 14 15:08:15 server2 imap[3125]: executed
This is what the imapd.conf looks like on both servers.
defaultpartition: imap1
configdirectory: /var/imap
partition-imap1: /var/spool/imap1
admins: cyrus support
srvtab: /var/imap/srvtab
quotawarn: 85
popminpoll: 0
autocreatequota: 30000
sasl_pwcheck_method: saslauthd
lmtp_over_quota_perm_failure: 1
allowusermoves: yes
proxy_authname: cyrus
proxy_password: password
The systems are in different subdomains sub1.domain.com and sub2.domain.com
and when I tried to do the hostname_password option it did not like dot's in
the name so I did short names and added the sub#.domain.com to the
resolv.conf so each host could ping by short name. I still got the error
from above so I changed the imapd.conf entry servername_password to
proxy_password since the cyrus account has the same password on both servers
and still got the error above.
Any ideas what I am missing?
Thank you
Perry

Thank you for the reply. Some follow up questions. (sorry to be so dense
I'm making this change on production servers so wanted to make sure I've
got it right).
SASL is running as: /usr/sbin/saslauthd -m /var/run/saslauthd -a pam
Our pam.d configs for both imap and pop look like
auth required /lib/security/pam_stack.so service=system-auth
account required /lib/security/pam_stack.so service=system-auth
Looking at the install-murder doc I should set up all the boxes like they
where frontends? (I pasted in what I think will only apply to my set up
from install-murder).
Additional backend configuration
If your authentication system requires usernames, passwords, etc, to
authenticate (e.g. it isn't Kerberos), then you will also need to specify
proxy_authname (and friends) in the backend imapd.confs as well. This is
so that the backends can authenticate to eachother to facilitate maibox
moves. (Backend machines will need to be full admins).
In short I just need to set up a common user account in the OS on each box
and define the user as proxy_authname: and put the password for that
account listed as host1_password: and host2_password etc....
Correct.
Do I need to add this proxy_authname to imapd.conf admins: as well for the
full admins requirement?
Yes.

Hi All,
We are running cyrus-imap 2.2.8 and sasl 2.1.15. We have two RHEL 3
servers with about 4800 users split between them.
I am looking to migrate the users to 2 new RHEL3 hosts with the same
cyrus-imap and sasl versions. I added the allowusermoves to imapd.conf
restarted cyrus and tried to do a test move.
host1.domain.com> xfer user/ host2.domain.com
xfermailbox: Mailbox does not exist
Both cyrus-imap and cyrus-sasl where compiled with --enable-murder (least
that is what my notes say is there a way to verify?), but it looks like
murder has not been set up with a master or imapd.conf file changes.
Question, Is it possible to xfer a mailbox without configuring murder?
Yes and no. You don't need mupdate, but the backends need to know how
to authenticate to each other. Look at install-murder.html and take a
look at the stuff regarding authentication. Also note that you can't
XFER the entire user/ hierarchy with one command, you have to do it one
user at a time. Assuming that you're using unixhierachysep, you would do:
xfer user/vbperry host2
