RE: glueing subtree and performance

["Howard Chu" <hyc@highlandsun.com>]

It depends on how you construct the search. If the server at domain.com has
no idea which subtree John is in, then yes, it will have to search those 50
subtrees to find his entry. If the signin info acquires John's username and
subtree name then of course you can avoid the wasted effort.
