Please delete this and the 'abc' comment. The web app ate the first reply after I was deemed to be "Unauthorized", but then apparently not and just did a test with the 'abc' after the initial reply was trashed!?

I too am looking for a solution to essentially the same problem of configuring a user account programmatically. I really can't fathom why Apple is making this so hard. Didn't it used to be as simple as editing some .plists and putting some entries in the key store? The 'solutions' I've found so far include using an Apple-mediated 'enterprise' solution (which is not appropriate), sending an email, or downloading a file from a web page! The last two require user actions, which is precisely what a series of defaults writes, or profiles -I or equivalent APIs sought to avoid. What is this 1995? Perhaps someone can point me to a more recent discussion of this matter if I don't find it or a solution first...
