iCal user unable to edit calendar
I have a Lion Server (10.7.4) that has several users and has been working for almost a year. All of a sudden 1 user is unable to edit his calendar, but other users are working fine. All his other services are working fine (mail, contacts).
If he adds entries via PC or iPad they do not appear on the web interface and are not synced between iPad and PC, so they remain only local to the device it is created on.
If I open his calendar via the web interface then I can see his entries up until this problem started but cannot edit or add new entries. The ones created after this problem on the iPad or PC do not appear.
If I send an invitation from another user then it appears in the web interface of the calendar.
I have looked at the Caldav log and can see no error message. No error comes up on the PC or iPad either.
I have connected from another iPad but the same problem.
There have been no recent software changes on the server.
He has 1 PC and 2 iPads connecting with his UID to this calendar. He has a secretary with Read/Write access. All this was working perfectly.
The only recent change has been adding several additional delegation users to his calendar with Read access.
To me it looks like his UID only has READ access to his calendar.
I have tried rebooting the server but no difference. I have also tried removing his access to the iCal service and adding it back.
I'm stuck on how to get this working, short of deleting/recreating his UID but then concerned with loosing his data.
I've been searching the forums but find no assistance yet.
