Problem Cause

Citrix Gateway App

Its a bug.
If an administrator upgrades or downgrades Citrix ADC through CLI without creating a directory under /var/nsinstall, then there is no mac directory getting created under ( /var/netscaler/gui/vpns/scripts ). Hence, they were getting Forbidden error message.
