Hi, I installed a CCS on Debian 8.7 and configure it to use an external LDAP. So fine, but... 1. I noticed that the LDAP-users do not get an e-mail while inviting to a new event. Contrary to external users, which receive an email containing an ics. Is there a possibility to send such IMIP-mails also to "internal" users? 2. How can I delegate a calendar? Or change the permissions so that other users can read / write into e.g. my calendar? I only found the "Calendar Web Administration"-page where I'm able to search for a resource. But as soon as I want to "manage" it, I will get a HTTP error 500. Maybe because I use my email-addresses as UID? However, is there another possibility to change the permissions of calendars? Thanks and regards, Steffen Menzel
