I have a website hosted on a regular hosting with my own IP and I purchased COMODO SSL for a year via my hosting provider. I have a primary domain and couple of add-on domains. Add-on domains are completely different domains residing in separate folders of my primary domain (kinda like sub-directories).

 

I don't really need SSL all that bad. I would probably use PayPal which has its own secured interface for credit card online transactions. BUT...what I do need is to be able to login securely into my Joomla backends where I enter my admin credentials. Obviously, SSL that I have is connected to my primary domain (hoster doesn't provide SSL for add-ons anyway). The good news is that I'm somehow being able to

use SSL on my add-ons' backends. I force SSL in Joomla configuration for a backend of Joomla and it seems to be working fine. The only thing is...browsers show me a warning messages that I simply ignore since I know what it's about. The warning is because the certificate was issued for a different domain (ie. my primary one only).

 

The question is...anyone can explain it and do you think SSL would work fine for ALL of the domains (one primary and 2 add-ons)?

You need a multi-domain cert.

You need a multi-domain cert.

 

Well, that's something that I propably would have to acquire directly from the CA, wouldn't I?

You think that multu-domain cert. can cover any domain, even an add-on one?

But the main point is money here. Of course, if money wasn't an issue I would just buy couple more certificates and that's it.

The whole idea is to SAVE money! Ie. pay for one cert. and use it on more than one domain!

You can order these types of SSL's through your SSL provider, here is some more information regarding multi domain SSL's: http://www.instantssl.com/ssl-certificate-products/ssl-certificate-ev-mdc.html?ap=InstantSSLJun12&key1sk5=3159&key1sk1=sem&gclid=CIytpKPszbICFYcPfAodGSAAmw

 

Just a note, these are not cheap as many have higher limits to what you might actually need. For instance the SSL cert I have linked too for more info has a limit of 100 domains but is over £500 a year. You can get single SSL's for £15/£30 a year, so if you really want SSL's on each domain it might work out cheaper to get separate hosting for each domain name and order a SSL for each.

 

Hope this helps

What about a wildcard SSL?

 

Wildcard SSL's only work as: *.domain.com / subdomain.domain.com etc... They do not work for different full domains only sub domains.
