    # == Description
    #
    # Creates a new URI::LDAP object from components, with syntax checking.
    #
    # The components accepted are host, port, dn, attributes,
    # scope, filter, and extensions.
    #
    # The components should be provided either as an Array, or as a Hash
    # with keys formed by preceding the component names with a colon.
    #
    # If an Array is used, the components must be passed in the
    # order <code>[host, port, dn, attributes, scope, filter, extensions]</code>.
    #
    # Example:
    #
    #     uri = URI::LDAP.build({:host => 'ldap.example.com',
    #       :dn => '/dc=example'})
    #
    #     uri = URI::LDAP.build(["ldap.example.com", nil,
    #       "/dc=example;dc=com", "query", nil, nil, nil])
