ssl certificate for multiple hostnames

[Liutauras Adomaitis]

Hi all,

I want to create ssl certificate for smtp, pop3, imap and http
services on kolab box which will accept multiple hostnames. As in
http://therowes.net/~greg/2008/01/08/creating-a-certificate-with-multiple-hostnames/
it should be possible, isn't it?

I'm not very good at understanding all the ssl stuff, but trying to ...
Qustions:
- Is it possible to have certificate which accepts multiple hostnames
(I have DNS server inside my lan and it is hosting kolab.local domain,
but form outside I use kolab.com domain)
- The link I refer to is saying  that I have to:
 -- modify openssl.cnf file
 -- create certificate request .csr
 -- create selfsigned ca.
Should I use kolab_ca.sh for that purpose?
Which openssl.cnf file should I modify ( I see that scripts are
creating temporary cnf files, so maybe edit scripts instead of
/kolab/etc/openssl/openssl.cnf file)
What should I know more? maybe running kolab_ca.sh will make some
undesirable changes.
How to do that to have minimum effect on running services?

Thanks for any hints
