Well, that's not really an "infrastructure" then is it? That's a single server running all the roles with no separation and protection that you get from separation. More importantly, PKI has many facets that have to be taken into account. You can't just leave the root CA machine on the network and have it available for people to attack (best practice to protect the root CA)and you have to have components in place to manage the crl's etc. If a single box is deployed, it fulfils the CA, RA, (and so on) roles. Splitting those roles is a best practice but you'll need them for a PKI; if your CA is also the RA then it has to be available for clients vs. being off-line and protected.
It all depends on the requirements. If you just need a cert to get a SSL web page running, then it may not be a big deal. If you intend to issue and manage certs, then you really need to consider your approach and best practices etc and it's likely that a single server CA isn't going to meet all your needs.

M�rz 2004 18:15 To: [EMAIL PROTECTED] Subject: [ActiveDir] PKI Infrastructure Question We are finally getting around to implementing the PKI infrastructure here and would like some advice. I had emailed several days ago about Ldap - unix box authenicating to AD - and I got that working (in my test lab). Here is what I was going to implement and would like some advice or direction if this is way off base. Root (Stand-alone) CA (offline) Subordinate Enterprise CA on DC Is this normal practice or completely wrong. Would you recommend install on DC or is that a major NO NO. Any thoughts, or advice...
