From e490415e2e300452e152373eb79fb437fb11449d Mon Sep 17 00:00:00 2001 From: Andrew Kroeger Date: Fri, 18 Jan 2008 02:51:51 +0100 Subject: When Windows attempts to create a new key, it looks for an available key name starting with "New Key #1" and iterating up to "New Key #99" before giving up. ldb_open_key() calls reg_path_to_ldb() to build the appropriate dn from the key name. reg_path_to_ldb() was not catching the error returned by ldb_dn_add_base_fmt() due to the unescaped '#' character, causing the returned dn to be that of the parent key, not the potential new key. Additionally, Windows expects a return value of WERR_BADFILE when a key does not exist, but WERR_NOT_FOUND was being returned instead. Correcting the building of the dn and the providing the expected return value allows new key creation to succeed. When attempting to delete a key, Windows passes the complete path to the key, not just the name of the child key to be deleted. Using reg_path_to_ldb() to build the correct dn allows key deletion to succeed.
