Configuring SSL VPN Connections
Configuring Secondary Authentication Attributes for an SSL VPN Connection
Profile
The Secondary Authentication dialog box lets you configure secondary or "double" authentication for
this connection profile. With double authentication enabled, the end user must present two sets of valid
authentication credentials in order to log on. You can use secondary authentication in conjunction with
pre-filling the username from a certificate. The fields in this dialog box are similar to those you configure
for primary authentication, but these fields relate only to secondary authentication.
When double authentication is enabled, these attributes select one or more fields in a certificate to use
as the username. Configuring the secondary username from certificate attribute forces the security
appliance to use the specified certificate field as the second username for the second username/password
authentication.
If you also specify the secondary authentication server group, along with the secondary username from
Note
certificate, only the primary username is used for authentication.
