User manual

The following URL prefixes are supported if end users will be copying and pasting the URL into
Horizon Client when Horizon Client is connected to an RSA-enabled Connection Server instance:
n
viewclient-securid://
n
http://127.0.0.1/securid/
End users can install the token by tapping the URL. Both prefixes viewclient-securid:// and
http://127.0.0.1/securid/ are supported. Note that not all browsers support hyperlinks that begin with
http://127.0.0.1. Also some file browsers, such as the File Manager app on the ASUS Transformer Pad,
cannot link the SDTID file with Horizon Client.
For information about using dynamic seed provisioning or file-based (CTF) provisioning, see the Web page

Instructions to End Users
When you create a CTFString URL or CT-KIP URL to send to end users, you can generate a URL with or
without a password or activation code. You send this URL to end users in an email that must include the
following information:
n
Instructions for navigating to the Install Software Token dialog box.
Tell end users to tap External Token in the Horizon Client dialog box that prompts them for RSA
SecurID credentials when they connect to a Connection Server instance.
n
CTFString URL or CT-KIP URL in plain text.
If the URL has formatting on it, end users will get an error message when they try to use it in
Horizon Client.
n
Activation code, if the CT-KIP URL that you create does not already include the activation code.
End users must enter this activation code in a text field of the dialog box.
n
If the CT-KIP URL includes an activation code, tell end users that they need not enter anything in the
Password or Activation Code text box in the Install Software Token dialog box.
Configure Advanced TLS/SSL Options
You can select the security protocols and cryptographic algorithms that are used to encrypt communications
between Horizon Client and Horizon servers and between Horizon Client and the agent in the remote
desktop.
By default, TLSv1.0, TLSv1.1, and TLSv1.2 are enabled. SSL v2.0 and 3.0 are not supported. The default
cipher control string is "!aNULL:kECDH+AES:ECDH+AES:RSA+AES:@STRENGTH".
If you configure a security protocol for Horizon Client that is not enabled on the Horizon server to which
the client connects, a TLS/SSL error occurs and the connection fails.
For information about configuring the security protocols that are accepted by Connection Server instances,
see the View Security document.
Procedure
1 Open Settings and tap Security options.
If you are connected to a remote desktop or application in full-screen mode, tap the Horizon Client
Tools radial menu icon and tap the gear icon to access Settings. If you are not using full-screen mode,
