I believe you are missing the proxyservers parameter on server2. From the
man page:
proxy_authname: proxy
The authentication name to use when authenticating to a backend
server in the Cyrus Murder.
proxy_password: <none>
The default password to use when authenticating to a backend server
in the Cyrus Murder. May be overridden on a host-specific basis
using the hostname_password option.
proxyservers: <none>
A list of users and groups that are allowed to proxy for other users,
seperated by spaces. Any user listed in this will be allowed to
login for any other user: use with caution.
On frontend servers, you would specify proxy_authname and proxy_password
to define how the frontend server connects to the backend server.
On backend servers, you would specify proxyservers to list which usernames
are allowed to proxy for other users.
So, on server2 I believe you need to specify proxyservers and on server1
you need to specify proxy_authname and proxy_password.

I thought nscd might have been tripping me up so I tried by IP address with
the same results. Also thought it may be an issue with a firewall between
these 2 hosts blocking a port so I tried 2 other cyrus servers that do not
have a FW between them with the same result (anyone know what port(s) xfer
uses?).
Any suggestions?
Thank you

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
