Do you have any instructions in general about generating cert requests 
and signing them with your CA?  If so, then they would mostly apply.  
You would use certutil to generate your CSR (certutil -R) for your 
server, then create the server cert on your CA from the server CSR, then 
install the new server cert in your server's key/cert db using certutil 
(certutil -A for an ascii/pem cert).

Anything which touches the key/cert databases (generate server cert 
request, add a cert) must use certutil.  The other operations can be 
done with openssl.

That will work fine for the SSL client side of things.  But 
setup-ds-admin cannot generate a server cert request, wait for the new 
cert to be issued, and install the new server cert.

Sure.  When you generate your cert request using certutil -R, use the -8 
argument to specify the subject alt names.  See also
