Hello! I use calendar server on Debian system. I have a chrooted environment and mounted a partition with the DCS data to this jail. Everything works fine. Today i change all hard drive this computer, i installed new version of Debian and smthing. I complete copied the jail to the new HDD and i make a new partition and from the old DCS data i copied the new partition. Mounted this partition with "user_xattr" and look like everything is ok. But the users cant connect to the calendar server and i dont know while. The generated log file is say: "2010-11-26 00:13:29+0100 [-] [caldav-8008] [-] "Error reading property ('DAV:', 'current-user-privilege-set') for resource /calendars/__uids__/9b4cede0-1434-5268-a1e4-8c2b59f0f296/: <StatusResponse 401 Access denied while reading property {DAV:}current-user-privilege-set.>"2010-11-26 00:13:29+0100 [-] [caldav-8008] [-] 401 response while getting property: ('DAV:', 'current-user-privilege-set') " Anybody try move the datas to another DCS instance?
