/*
* delete the default ACL of a directory
*
* This is achieved by fetching the access ACL and rewriting it
* directly, via the solaris system call: the SETACL call on
* directories writes both the access and the default ACL as provided.
*
* XXX: posix acl_delete_def_file returns an error if
* the file referred to by path is not a directory.
* this function does not complain but the actions
* have no effect on a file other than a directory.
* But sys_acl_delete_default_file is only called in
* smbd/posixacls.c after having checked that the file
* is a directory, anyways. So implementing the extra
* check is considered unnecessary. --- Agreed? XXX
