Problems with murder upgrade from 2.2.13 to 2.5.8

[Mathieu Pellieux]

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.
