r17150: MMC User & group plugins fixes:
* Make sure to lower case all usernames before calling the create, delete, or rename hooks. * Preserve case for usernames in passdb * Flush the getpwnam cache after renaming a user * Add become/unbecome root block in _samr_delete_dom_user() when trying to verify the account's existence. (This used to be commit bbe11b7a950e7d85001f042bbd1ea3bf33ecda7b)
