Horizon TrueSSO configure failed

I configure Horizon True SSO on the basis of this documents:

Setting Up True SSO

When I enter the command to create a True SSO connector:

vdmUtil --authAs admin-role-user --authDomain domain-name --authPassword admin-user-password --truesso --create --connector --domain domain-fqdn --template TrueSSO-template-name --primaryEnrollmentServer enroll-server-fqdn --certificateServer ca-common-name --mode enabled

I have a issue before enter this command:

Horizon True SSO configure issue

What should I do?
