Yes, that page needs rewriting a bit, but what it says is essentially true.

That is using idmap_ad, a DC uses idmap.ldb, a totally different beast 
which uses xidNumber attributes.

Sorry, but you cannot, this is one of the reasons not to use a DC as a 
fileserver, you have to use the 'template homedir' parameter and all 
users get the same home directory path.
