Re: error authentication Frontend and backend Mupdate

Hi Mateus,

You'll need to also set "proxyservers: cyrus" on your backends to tell them to permit the cyrus user to proxy.  I have no idea why that setting is called "proxyservers" when it is a list of users/groups...

Here's the description from the imapd.conf(5) man page:

proxyservers: <none>
      A  list  of users and groups that are allowed to proxy for other
      users, separated by spaces.  Any user listed in this will be al‐
      lowed to login for any other user: use with caution.  In a stan‐
      dard murder this option should ONLY be set on backends.  DO  NOT
      SET on frontends or things won't work properly.

Cheers,

ellie
