I answered the question myself today with some additional manual digging in the archives of this list. Ultimately, I understood the direction provided in another thread to use the CalDAVClientLibrary to manage relationships and ACLs of principals. However, I could not make successful changes to any of the principals in my XML Directory. It turns out that my principal URL has a trailing slash, which is material in parsing the URL string. I was using /principals/__uids__/user and needed to use /principals/ __uids__/user/. Delegates work and I am on to the next problem, address completion via LDAP. Thanks for anyone that spent brain cycles reading this. Corey On Dec 15, 2008, at 10:27 AM, Corey Scobie wrote:

I am running latest DCS with XML File Directory Service. I want to define user "B" and give them read/write access to the calendars in user A's store. I have tried defining a proxy on the user principal object but it appears that users cannot have proxies. Do I really need to define user A as a resource principal?

Sorry if I am being thick here. I have researched hours on this subject and still do not have a definitive answer on defining delegates for a user using XML File Repository.

Thanks in advance.
