[Pki-users] setting DNSName in subjectAltName extension

I need to set DNSName in server subjectAltname extensions, but having difficulty getting the server's name into this field. I've read this: https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Certificate_System... I can set the RFC822name value using this (see table B-15) $request.requestor_email$ by making sure there's a requestor_email=something in the GET from the RA. There really isn;t anything that corresponds to what DNSName should be but I expected $request.subject$ would do; I added subject=some.thing.dom, but no, I get "$request.subject$" as a literal string. I also tried the obviously wrong example in Example B.1 (before the table) - policyset.serverCertSet.9.default.params.subjAltExtPattern_1=$request.SAN1$ same thing, $request.SAN1$ literal. I can set subjAltExtPattern_1 to my own literal string, but obviously that's counterproductive. I can set it to $request.requestor_email$ and get the email address in DNSName - if I didn't have cases where BOTH subjectAltName fields were needed I'd just re-purpose requestor_email. So - what works and how? I'm stumped. Any ideas appreciated. Thanks, ==mwh
