HTTP or LDAP for CRL

$
0
0

Hello

I am setting up a new PKI (in a LAB initially) an reading up on the subject.

I see the default location for the CDP is in the Configuration partition in AD and therefore accessed via LDAP://......

I also see other recommending using IIS/HTTP to publish the CRL, CPS

I can see the advantage of publishing the CPS via HTTP (not sure how you would import a file e.g. text file containing the CPS into AD in any event)

Question 1:

But what are the main advantages/disadvantages of placing the CRL in an IIS site and therefore HTTP?

Question 2:

I can see how the AD integrated CA would publish updated CRL to AD as the CA is integrated (e.g. Sub issuing CA)

If the CRL is published via IIS/HTTP will the CA be able to automatically update the CRL via HTTP PUT or something like that (and if so I assume the CA Server needs rights to the Site and underlying NTFS folder containing the sites files), or will I have to manually download the CRL from the CA and publish to the HTTP site manually (or via script)?

Question 3:

Can I have the CRL published to LDAP and HTTP at the same time, and therefore I assume I will have to update the CA in come where so when it issues certificates is states both location in the CDP information within the certificate?

Any help most appreciated
