Re: Self-Signed Certificates

Brad

We are on V7R1M0 but we were doing this on V5R4M0 also. I don't recall ever seeing such an error message - although the error messages DCM gives you for certificate imports are never 100% accurate. They might as well say "I couldn't do that. I don't know why, but here is a guess...."

It doesn't make any sense anyway. Let's say you have purchased a certificate for your web facing windows servers from a well-known CA - and spent a shedload of money doing so. Then you decide to add an IBMi to your array of web facing servers. If the rule was that you have to have generated a certificate request from the IBMi in order to import the certificate, you would be stuffed. You'd have to buy a brand new certificate just for the IBMi things. It wouldn't surprise many if that was the case, but luckily it is not.

Here is an example of a customer in Germany who had a GeoTrust certificate long before they exposed an IBMi to the web. The certificate was later imported into DCM: https://portal.unitymedia.de without having to generate a request first.

Maybe there is something in the certificate contents that causes the error to which you allude or, more to the point, causes the check to be bypassed.

Cheers
Kevin

Hi, Kevin.

I just tried with a couple server certificates I have for customers and always get:

"No request key is found for the certificate. If you are trying to receive the signed certificate, you must be using the same certificate store that was used when the certificate was requested. If this is a CA certificate, you should use the function for importing a CA."

Just as expected. So I'm not sure what you're doing different, or if you're on a different OS level (this is on V5R4 BTW).

Steps:
Start DCM
Select *SYSTEM Store
Expand All
Select Import Certificate
Select SERVER
Enter path

I can 100% guarantee you do not need a matching request in DCM. I
have imported many server certificates into DCM and have never once
had he need to generate the initial request from DCM. The only trouble
I have had is when the CA chain is not already present (which that
forum post circumnavigated).

Kevin,

DCM has required a matching request when importing a certificate
(unless things have changed in newer OS releases.. which hopefully they have).
I've always just done things by the book.. I guess. :)

Your document explains how to import the CAs if required, but I didn't
see how you'd bypass the requirement DCM gives you of having a matching
request. There's not mention of the error you would get stating the
matching request is required.

I've actually never tried to bypass this requirement of DCM, and I'm
sure it is possible and would be required in some instances,
especially when using a wildcard certificate.

Sorry Brad, but that is not the case. You don't have to make the request
from DCM in order to be able to import it into DCM. For example, our
certificate covers several servers and domains, only one of which is
served from an IBMi. You can import any certificate from a trusted
CA into DCM regardless of where the request was created. What is
true is that DCM does not make it simple to do so - unlike Windows
for example. It can be a bit of a pain, but if you know what you
are doing you can do it. I went through the pain of importing a
GoDaddy certificate on our IBMi and documented the process here:

Just to note, that process isn't complete.

You have to make a request first using DCM that you give to the
certificate provider. Then when you get it you import it.

It won't let you import a certificate without a request.

Also, you may need to import the CA(s) used by the certificate into
your *SYSTEM store first as well.

So the sequence is more like this:

1. Create a server certificate request using DCM 2. Give that to
your Certificate source (they will ask for it).
3. Import the certificate. Possibly importing the CAs used by the
certificate first if required.
