Hi! I'm using a LDAP server for user information and authentication. However, the entryUUID attribute is not exported through LDAP. I've tried not using an attribute: --- <key>guidAttr</key> <string>entryUUID</string> --- but it doesn't work. It fails with a trace such as: --- 2011-07-21 21:38:28+0300 [-] [caldav-8008] File "/usr/lib/twisted-calendarserver/lib/python2.6/site-packages/twistedcaldav/directory/calendar.py", line 164, in getChild 2011-07-21 21:38:28+0300 [-] [caldav-8008] return self._parent.homeForDirectoryRecord(record) 2011-07-21 21:38:28+0300 [-] [caldav-8008] File "/usr/lib/twisted-calendarserver/lib/python2.6/site-packages/twistedcaldav/directory/calendar.py", line 122, in homeForDirec toryRecord 2011-07-21 21:38:28+0300 [-] [caldav-8008] return uidResource.getChild(record.uid) 2011-07-21 21:38:28+0300 [-] [caldav-8008] File "/usr/lib/twisted-calendarserver/lib/python2.6/site-packages/twistedcaldav/directory/calendar.py", line 226, in getChild 2011-07-21 21:38:28+0300 [-] [caldav-8008] return self.provisionChild(name) 2011-07-21 21:38:28+0300 [-] [caldav-8008] File "/usr/lib/twisted-calendarserver/lib/python2.6/site-packages/twistedcaldav/static.py", line 653, in provisionChild 2011-07-21 21:38:28+0300 [-] [caldav-8008] assert len(name) > 4, "Directory record has an invalid GUID: %r" % (name,) 2011-07-21 21:38:28+0300 [-] [caldav-8008] exceptions.AssertionError: Directory record has an invalid GUID: '9000' --- Is there any workaround in case the entryUUID attributed is not exported?
