As the first part of the two-factor authentication process, Barracuda SSL VPN sends the user name and the password to AD/LDAP. 3. If AD/LDAP authenticates the user name and the password, AD/LDAP returns the group permission VIP Integration Guide for Barracuda SSL VPN Page 2 of 14

3 details and the authentication response to Barracuda SSL VPN. 4. As the second part of the two-factor authentication process, Barracuda SSL VPN sends the user name and the security code to the Validation Service. 5.
