If you have multiple Connection Server instances, you can configure two-factor authentication
on some instances and a different user authentication method on others. For example, you can
configure two-factor authentication only for users who access remote desktops and applications
from outside the corporate network, over the Internet.
Horizon 7 is certified through the RSA SecurID Ready program and supports the full range
of SecurID capabilities, including New PIN Mode, Next Token Code Mode, RSA Authentication
Manager, and load balancing.
n Logging in Using Two-Factor Authentication
When a user connects to a Connection Server instance that has RSA SecurID authentication
or RADIUS authentication enabled, a special login dialog box appears in Horizon Client.
n Enable Two-Factor Authentication in Horizon Administrator
You enable a Connection Server instance for RSA SecurID authentication or RADIUS
authentication by modifying Connection Server settings in Horizon Administrator.
n Troubleshooting RSA SecurID Access Denial
Access is denied when Horizon Client connects with RSA SecurID authentication.
n Troubleshooting RADIUS Access Denial
Access is denied when Horizon Client connects with RADIUS two-factor authentication.
Logging in Using Two-Factor Authentication
When a user connects to a Connection Server instance that has RSA SecurID authentication or
RADIUS authentication enabled, a special login dialog box appears in Horizon Client.
Users enter their RSA SecurID or RADIUS authentication user name and passcode in the a special
login dialog box. A two-factor authentication passcode typically consists of a PIN followed by a
token code.
n If RSA Authentication Manager requires users to enter a new RSA SecurID PIN after entering
their RSA SecurID username and passcode, a PIN dialog box appears. After setting a new PIN,
users are prompted to wait for the next token code before logging in. If RSA Authentication
Manager is configured to use system-generated PINs, a dialog box appears to confirm the
PIN.
n When logging in to Horizon 7, RADIUS authentication works much like RSA SecurID. If the
RADIUS server issues an access challenge, Horizon Client displays a dialog box similar to the
RSA SecurID prompt for the next token code. Currently support for RADIUS challenges is
limited to prompting for text input. Any challenge text sent from the RADIUS server is not
displayed. More complex forms of challenge, such as multiple choice and image selection, are
currently not supported.
After a user enters credentials in Horizon Client, the RADIUS server can send an SMS text
message or email, or text using some other out-of-band mechanism, to the user's cell phone
with a code. The user can enter this text and code into Horizon Client to complete the
authentication.
