I have a web site on an internal iis 6.0 server. Some users use the host
header name of the website with the domain attached and some connect without:

for example:

https:\internal vs https:\internal.company.com

I have an SSL certificate that has the host header name and those that
connect without the domain connect straight through, no errors. If they use
the https:\internal.company.com however they get a certificate error as the
name is different then the certifcate. I can change the certificate to
include the domain but then the host header name by itself gives the error.

is there a way to allow both to work without a certificate error?

I tried a spin on the wildcard certificate creating a request with
"internal.*" but that was no go as well. Do you need to "turn anything on" to
get IIS 6.0 to accept the "*" maybe?

Certificates authorized through an internal 2003 CA

thanks

That's not the way wild carding works. It only works for the leftmost
label.

Rather than allowing everything in a domain (which you can't don) you are
better off enumerating all the FQDNs that you want users to be able to
access, and then including them in the certificate Subject Alternative Name
field (or even as multiple CNs in the Subject field).

The SAN seems like the way to go from reading up on a description of it.

Thanks very much for the information! Now to research the implementation
part!

Have a great day and thanks again!

Certificates with SAN names are typically created with the Exchange
2007 Management Shell. (http://www.digicert.com/csr-creation-microsoft-
unified-communications.htm) This is because SANs weren't commonly used
before Exchange 2007 started using them. If you have Exchange 2007,
you can generate the cert and after installing it, assign it to be
used by an IIS website.

However, most CAs allow you to generate a normal CSR in IIS and then
add the additional SAN names during the ordering process. If you are
looking for a commerical certificate, you can compare SAN/UC
certificates here: http://www.sslshopper.com/unified-communications-uc-ssl-c=
ertificates.html
