Re: Certificates trouble: CRL not available(?) and "revocation server offline" error



First thing that I would do is validate the CDP and AIA extensions.
Run pkiview.msc (from the resource kit tools) and verify that *all* CDP and
AIA points are considered Valid (expiring is OK too).

Hello to all!!!

I had installed EntRoot and EntIssuing CAs for my test environment
(they are both online), and after that configured them like this:

EntRoot
- CDP and AIA locations left on default.
- Base CRL publication is 1 week, no Delta CRLs.
- Deleteted all cert tmpls from CA>Certificate Templates except
Subordinate Certification Authority.


EntIssuing
- CDP and AIA locations left on default
- Base CRL publication is 1 Days, Delta CRL publication is 6 hours, and
AD replication is 2 hours (as this is my test environment)
- Created new FirmaEFS cert tmpl upon the Basic EFS, on its
Properties>Superceded Templates tab add Basic EFS, and after that
deleted Basic EFS from CA>Certificate Templates.

Trouble is: I obtained some certificates based upon the FirmaEFS cert
tmpl on my client computer for two different users, by using
Certificates snap-in console. However, when I try to use them for
encryption of files I get some errors:
- When I try to encrypt files, a new local certificate is self-issued
to the user and used for encryption (that is not part of the CA
hierarchy), and not that obtained for EntIssuing CA. Is it possible to
force user cert obtained from EntIssuing CA to be used for encryption
(i.e. to manually select certificate that will be used)?
- When I try to add certificate of users issued by EntIssuing CA, on
the Encryption Details dialog of the file, I receive ?revocation server
offline? error. Then I manually checked that CDP and AIA locations are
available, and they are, but it seems that clients cannot access them.
How can I troubleshoot whether clients have the access to the CRLs?
- Furthermore, in Certificates snap-in console on client, in
Intermediate Certification Authority>Certificate Revocation List node,
there's no EntIssuing CRL. I imported it manually, restarted the
client, but I have the same error symptoms as previously. How can I see
that client is consulting this CRL for revocation, and does it use some
other ones from its cached locations?

I would appreciate if you can help me with this!
