Hello,

Aren't you missing the folowwing ACLs? (since cyrus 2.3 at least)

k: The ACI subject has the right to CREATE a new folder if the /k/ <http://www.cyrusimap.org/%7Evanmeeuwen/imap/admin/access-control/rights-reference.html#imap-admin-access-control-right-k> right exists on the parent folder of the folder to be created. x: Use the /x/ <http://www.cyrusimap.org/%7Evanmeeuwen/imap/admin/access-control/rights-reference.html#imap-admin-access-control-right-x> right to indicate the ACI subject has the right to DELETE the folder on which the ACL is set, as opposed to the now obsolete /c/ <http://www.cyrusimap.org/%7Evanmeeuwen/imap/admin/access-control/rights-reference.html#imap-admin-access-control-right-c> right or /d/ <http://www.cyrusimap.org/%7Evanmeeuwen/imap/admin/access-control/rights-reference.html#imap-admin-access-control-right-d> right. t: The ACI subject is allowed to delete messages from this folder, meaning that the ACI subject is allowed to flag messages as \\Deleted. e: The ACI subject is allowed to expunge messages in this folder, meaning the ACI subject has the right to remove all messages that have been flagged as \\Deleted from all visibility.

Hello,

I'm on the way to make a big (late) upgrade.

My murder config is composed of 16 1To backends. I can't upgrade
all of them simultaneously. So I planed to :

   - upgrade mupdate server (make a new one, and update frontend's and
     backend's conf)
   - replace frontends with upgraded one's
   - upgrade backends one after the other, nightly, on serveral night

mupdate server upgrade is ok. But I have problems with 2.5 frontends and 2.2
backends interaction. All seems fine (no error), but users can't create new sub
mailboxes (admin can create mailboxes and sub mailboxes) :

loggued as mailbox owner :
imap-01> lam INBOX
delepine lrswipcda
anyone p
imap-01> cm INBOX.hop
createmailbox: Permission denied

My tests say that, whichever mupdate server version :
   Frontend 2.2 can create 2.2 mailboxes and 2.5 mailboxes
   Frontend 2.5 can't create 2.2 mailboxes but can create 2.5 mailboxes

All others tested features work.

The 2.2 is using saslauthd + pam_ldap for authentification. The 2.5 is using 
either
ldapdb or saslauthd + ptoader and ldap.

With or without
   suppress_capabilities: ESEARCH QRESYNC XLIST LIST-EXTENDED WITHIN
on 2.5 frontends.

2 questions :
   - do you have an idea why users can't create submailboxes on 2.2
     backends with 2.5 frontends ? Is there any acl new option I
     miss ? ...
   - what are the risks if I wait for all backends to migrate before
     using 2.5 frontends ? My option with this problem. I didn't find
     any problem... but surely, if there's one, my users will find it.

Options that might be relevant :
On backends :
   proxyservers: proxy
   proxy_authname: proxy

On frontends:
   proxy_authname: proxy
   proxy_password: <>
   proxyd_allow_status_referral: 0
   proxyd_disable_mailbox_referrals: 1

backends are in an internal non routable network.

Sincerly,
       Jean Charles Delépine
