When I create a user, we let the user access our "shared inboxes" by having the user be member of a group cm user.[userid] sam user.[userid] group:sharedmail lrswipcda For this to work out the sharedmail group must also be a unix group, and each user must be a unix member of the group by modifying /etc/group . Until the recent system upgrade, there seemed to be no need for the users to have a unix account, but after the upgrade Cyrus would segfault when trying to access a shared mailbox, until I created unix accounts for all the mail users Now the procedure for creating a new mail user with shared mailbox access is: cm user.[userid] sam user.[userid] group:sharedmail lrswipcda useradd -M userid usermod -aG sharedmail userid in /etc/imapd.conf i have sasl_pwcheck_method: auxprop Any comments are welcome :-) ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
