RDP settings policies define protocol-level settings (timeout, display, protocol version, and authentication). You can create multiple policies, and choose the appropriate one for each RDP connection.

URL

GET https://<IP-address-of-SPS>/api/configuration/rdp/settings_policies

Cookies

Cookie name	Description	Required	Values
session_id	Contains the authentication token of the user	Required	The value of the session ID cookie received from the REST server in the authentication response, for example, a1f71d030e657634730b9e887cb59a5e56162860. For details on authentication, see Authenticate to the SPS REST API. Note that this session ID refers to the connection between the REST client and the SPS REST API. It is not related to the sessions that SPS records (and which also have a session ID, but in a different format).

Sample request

The following command lists RDP settings policies.

curl --cookie cookies https://<IP-address-of-SPS>/api/configuration/rdp/settings_policies

The following command retrieves the properties of a specific policy.

curl --cookie cookies https://<IP-address-of-SPS>/api/configuration/rdp/settings_policies/<policy-id>

Element		Type	Description
key		string	Top level element, contains the ID of the policy.
body		Top level element (string)	The elements of the RDP settings policy.
	autologon_domain_suffix	string	Enter the suffix that the client will append to the domain when using autologon in conjunction with Network Level Authentication (CredSSP).
	name	string	Name of the RDP settings policy. Cannot contain whitespace.
	permit_unreliable_usernames	boolean	Set to true to automatically terminate RDP connections if SPS cannot reliably extract the username.
	preconnect_channel_check	boolean	Before establishing the server-side connection, SPS can evaluate the connection and channel policies to determine if the connection might be permitted at all. The server-side connection is established only if the evaluated policies permit the client to access the server. To enable this function, set the parameter to true.
	protocol_features	Top level item	Settings for RDP protocol versions, and Network Layer Authentication.
	screen	Top level item	Display size and depth settings.
	timeout	int	Connection timeout, in seconds. Note that the SPS web UI displays the same value in milliseconds.
	userauth_banner	string	You can display a banner message to the clients before authentication.

Elements of protocol		Type	Description
nla		Top level item	Settings for Network Level Authentication.
	enabled	boolean	Set to true to enable Network Level Authentication. If set to true, the require_domain_membership element is required in the JSON.
	require_domain_membership	boolean	Set to true to require domain membership. Must be in the JSON if NLA is enabled.
rdp4_auth_enabled		boolean	Set to true to enable RDP4 authentication within the RDP5 protocol. This might be needed for compatibility reasons with certain client applications.
rdp4_enabled		boolean	Set to true to enable the version 4 of the Remote Desktop Protocol.
rdp5_enabled		boolean	Set to true to enable the version 5 of the Remote Desktop Protocol. To also configure SSL-encryption for RDP5, enable the nla element, or configure a Signing CA in your connection policies.

Elements of screen	Type	Description
maximum_bpp	int	The maximum allowed color depth of the remote desktop, in bits. The following values are valid: 8, 15, 16, 24.
maximum_height	int	The maximum allowed height of the remote desktop, in pixels.
maximum_width	int	The maximum allowed width of the remote desktop, in pixels.

Examples:

Turn off NLA.

Add RDP settings policies

To add a settings policy, you have to:

1. Open a transaction.

   For details, see Open a transaction.

2. Create the JSON object for the new policy.

   POST the JSON object to the https://<IP-address-of-SPS>/api/configuration/rdp/settings_policies/ endpoint. You can find a detailed description of the available parameters listed in the table of RDP settings policy parameters.

   If the POST request is successful, the response includes the key of the new policy. For example:

   {
     "key": "9c3a0419-53e6-43a4-902c-2b3b0ce7a7a7",
     "meta": {
       "href": "/api/configuration/rdp/settings_policies/9c3a0419-53e6-43a4-902c-2b3b0ce7a7a7",

   }

3. Commit your changes.

   For details, see Commit a transaction.

Modify RDP settings policies

To modify a settings policy, you have to:

1. Open a transaction.

   For details, see Open a transaction.

2. Modify the JSON object of the policy.

   PUT the modified JSON object to the https://<IP-address-of-SPS>/api/configuration/rdp/settings_policies/<key-of-the-object> endpoint. You can find a detailed description of the available parameters listed in the table of RDP settings policy parameters.
