Hi all

When configure IOS CA server, you have an option to configure for

router3(cs-server)#database url cnm ?
  WORD     URL of primary storage location
  publish  Store a copy at a storage location



All non-critical CS files cnm, crl, crt can be published and used for any
other purpose.

I am wondering why do we need a separate publish location. The cnm, crl, crt
files can be directly taken from storage location. The following configures
storage location and publish location.
I can take the crl file from flash itself right, why do I need a publish
location? Does publish location have any special functionality that the
storage location doesn't have?"

database url crl flash:
database url crl publish nvram:

Certificate Server Database File Publication

A publish file is a copy of the original file and is available for other
processes to use or for your use. If the certificate server fails to publish
a file, it does cause the server to shut down. You may specify one publish
location for the issued certificates file and name file and multiple publish
locations for the CRL file. See Table 2 <#wp1193846> for files types
available for publication. You may publish files regardless of the database
level that is set.

Table 2

  File Extension
 File Type

.crl

The CRL publish location.

.crt

The issued certificates publish location.

.cnm

The certificate name and expiration file publish location.
