When a private certificate with CA information is imported, the client displays CA information and private certificate
information in System Tools > Certificates.
Proxy is enabled for configured applications only, irrespective of availability of DHCP 252. If you configure empty value
on Local UI, the Local UI helps to enable for all supported applications by default. If you configure empty value on Wyse
Management Suite or Admin Policy Tool, proxy is enabled for none according to the Proxy Application List configuration. If
DHCP 252 is available, the Wyse Management Suite is enabled to go through proxy by default even when Wyse Management
Suite is not configured in Proxy Application List configuration.
Simple Certificate Enrollment Protocol (SCEP) auto renewWhen auto renewal happens on the client, the client needs
password to renew the client certificate. If you are using an enrollment password which can expire in some time, the
enrollment password should be valid when auto renew behavior happens on the client. Dell Technologies recommends you to
use admin credentials, or fixed enrollment password to auto enroll certificate, and auto renew certificate.
