    Caution: In your WALLIX Bastion account, the WALLIX Bastion super admin must have enabled "credential recovery" on your account for PAM to be enabled. Otherwise, your scan may not return any results. For more information, see your WALLIX Bastion documentation.

    Note: Multiple options for privilege escalation are supported, including su, su+sudo and sudo. For example, if you select sudo, more fields for sudo user, Escalation Account Name, and Location of su and sudo (directory) are provided and can be completed to support authentication and privilege escalation through WALLIX Bastion PAM. The Escalation Account Name field is then required to complete your privilege escalation.
