that does not or cannot have Horizon Client software installed on its operating system. The Horizon Client
software offers more features and better performance.
The following Web browsers are supported for HTML Access 4.7:
n
Chrome 62 and 63
n

How Do I Log In? 2
Before you can log in and connect to a remote desktop or application, a system administrator at your
company must set up your user account. If your system administrator has not set up your user account,
you cannot use Horizon Client or HTML Access.
If Horizon Client prompts you for a server name and domain name, your system administrator must tell
you the server name to type and domain to select. At some companies, Horizon Client automatically
connects to the correct server and selects the correct domain for you.
If you do not know your user name or password or how to reset your password, contact the system
administrator at your company.
When you are ready to log in and get started, see Connect to a Remote Desktop or Application.

Connecting to Remote Desktops
and Applications 3
You can use Horizon Client to connect to remote desktops and applications.
This chapter includes the following topics:
n
Connect to a Remote Desktop or Application
n
Trust a Self-Signed Root Certificate
n
Use Unauthenticated Access to Connect to Remote Applications
n
Log Off or Disconnect
Connect to a Remote Desktop or Application
Use your Active Directory credentials to connect to the remote desktops and applications that you are
authorized to use.
Prerequisites
n
Obtain login credentials, such as an Active Directory user name and password, RSA SecurID user
name and passcode, or RADIUS authentication user name and passcode.
n
Obtain the NETBIOS domain name for logging in. For example, you might use mycompany rather than
mycompany.com.
Procedure
1 In the Login dialog box, if you are prompted for RSA SecurID credentials or RADIUS authentication
credentials, enter the user name and passcode, and click Login.
The passcode might include both a PIN and the generated number on the token.
2 If you are prompted a second time for RSA SecurID credentials or RADIUS authentication
credentials, enter the next generated number on the token.
Do not enter your PIN and do not enter the same generated number entered previously. If necessary,
wait until a new number is generated.
If this step is required, it is required only when you mistype the first passcode or when configuration
settings in the RSA server change.

3 In the Login dialog box, enter your login credentials.
a In the Username text box, enter your valid Active Directory user name in either username,
domain\username, or username@domain format.
If the Domain text box is disabled, you must use either the domain\username or
username@domain format.
b Enter your password.
c (Optional) If the Domain text box is enabled, select a domain name, if it is not already correctly
populated.
Note To cancel the login process, click Cancel before the login process finishes.
4 (Optional) On the desktop and application selection screen, before you select the item you want to
access, to mark a remote desktop or application as a favorite, click the gray star inside the icon for
the desktop or application.
The star icon turns from gray to yellow. The next time you log in, you can click the star icon in the
upper-right part of the browser window to display only favorites.
5 Click the icon for the remote desktop or application that you want to access.
The remote desktop or application is displayed in your browser. A navigation sidebar is also available.
You can click the tab at the left side of the browser window to display the sidebar. You can use the
sidebar to access other remote desktops or applications, display the Settings window, copy and paste
text, and more.
What to do next
If, soon after connecting to a desktop or application, you get disconnected and see a prompt asking you
to click a link to accept the security certificate, you can select whether to trust the certificate. See Trust a
Self-Signed Root Certificate.
Trust a Self-Signed Root Certificate
In some cases, when connecting to a remote desktop or application for the first time, you might be
prompted by the browser to accept the self-signed certificate used by the remote machine. You must trust
the certificate before the connection can be made to the remote desktop or application.
Most browsers will give you the option to permanently trust the self-signed certificate. If you do not
choose to permanently trust the certificate, you must verify the certificate every time you restart your
browser. If you are using a Safari browser, you must permanently trust the security certificate in order to
establish the connection.
VMware, Inc. 7
VMware Horizon HTML Access User Guide
Procedure
1 If your browser presents an untrusted certificate warning or a warning that your connection is not
private, examine the certificate to verify that it matches the certificate that is used by your company.
You might need to contact your Horizon administrator for assistance. For example, in a Chrome
browser, you might use the following procedure.
a Click the lock icon in the address bar.
b Click the Certificate information link.
c Verify that the certificate matches the certificate that is used by your company.
You might need to contact your Horizon administrator for assistance.
2 Accept the security certificate.
Each browser has its own browser-specific prompts for accepting or always trusting a certificate. For
example, in a Chrome browser, you can click the Advanced link on the browser page, and click
Proceed to server-name (unsafe).
In a Safari browser, use the following procedure to permanently trust the certificate.
a Click the Show Certificate button when the untrusted certificate dialog box appears.
b Select the Always Trust check box and click Continue.
c When prompted, provide your password and click Update Settings.
The remote desktop or application is launched.
Use Unauthenticated Access to Connect to Remote Applications
A Horizon administrator can use the Unauthenticated Access feature to create Unauthenticated Access
users and entitle those users to remote applications on a Connection Server instance. Unauthenticated
Access users can log in to the server anonymously to connect to their remote applications.
Prerequisites
Obtain the following information from your Horizon administrator:
n
Server name to use for connecting to the server.
n
An Unauthenticated Access user account to use for logging in anonymously.
Procedure
1 Open a browser. Use one of the following URI syntaxes to connect to the Connection Server instance
on which you have unauthenticated access to remote applications.
n
https://authority-part?unauthenticatedAccessEnabled=true
VMware, Inc. 8
VMware Horizon HTML Access User Guide
n
https://authority-part?
unauthenticatedAccessEnabled=true&unauthenticatedAccessAccount=anonymous_account
In the above URI syntaxes, the authority-part specifies the server address and, optionally, a non-
default port number. Server names must conform to a DNS syntax. To specify a port number, use the
following syntax: server-address:port-number . The anonymous_account is the Unauthenticated
Access user account created for logging in anonymously.
Connections to Connection Server always use SSL. The default port for SSL connections is 443. If
Connection Server is not configured to use the default port, use the format shown in this example:
horizon.company.com:1443.
2 (Optional) If you did not specify the unauthenticatedAccessAccount query, select an
Unauthenticated Access user account from the User account drop-down menu, if necessary, and
click Submit.
If only one Unauthenticated Access user account is available, the user account is selected by default.
The application selection window appears.
3 Click the icon for the remote application that you want to access.
The remote application is displayed in your browser. A navigation sidebar is also available. You can
click the tab at the left side of the browser to display the sidebar. You can use the sidebar to access
other remote applications, display the Settings window, copy and paste text, and more.
Note You cannot reconnect to unauthenticated application sessions. When you disconnect from the
client, the RDS host logs off the local user session automatically.
Log O or Disconnect
With some configurations, if you disconnect from a remote desktop without logging off, applications in the
desktop can remain open. You can also disconnect from a server and leave published applications
running.
Procedure
n
Log out of the server and disconnect from (but do not log out from) the desktop or quit the hosted
application.
Option Action
From the desktop and application
selector screen, before connecting to a
remote desktop or application
From the sidebar when connected to a
remote desktop or application
Click the Log Out toolbar button in the upper-right corner of the screen.
Click the Log out toolbar button at the top of the sidebar.

Shortcut Key Combinations
Regardless of the language used, some key combinations cannot be sent to the to a remote desktop or
application.
Web browsers allow some key presses and key combinations to be sent to both the client and the
destination system. For other keys and key combinations, the input is processed only locally and is not
sent to the destination system. The key combinations that work on your system depend on the browser
software, the client operating system, and the language settings.
Note If you are using a Mac, you can map the Command key to the Windows Ctrl key when using the
key combinations to select, copy, and paste text. To enable this feature, you can click the Open Settings
Window toolbar button in the sidebar and turn on Enable Command-A, Command-C, Command-V,
and Command-X. (This option appears in the Settings window only if you are using a Mac.)
The following keys and keyboard combinations often do not work in remote desktops:
