BasicConstraintsExt Plug-in Module
Because the basic constraints extension is a critical extension and is used by
applications to determine the path length during certificate validation to chain up
to the trusted CA, it's important that you set this extension correctly.
Also note that when a user submits a certificate request using the
manual-enrollment method, the basic constraints extension is set on that request as
per the configured policy, and then the request is queued for agent approval. When
an agent approves the request, it is subjected to the configured policy again. If
there's a change in the configuration of the basic constraints extension, the server
may reject the agent-approved request. For the server to approve the request, the
user will have to resubmit the request.
During installation, Certificate Management System automatically creates an
instance of the basic constraints extension policy. See "BasicConstraintsExt Rule"
on page 147.
