does xfer require murder?

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.
