I updated the extension to Let's Encrypt 2.0.0-21 and do not see any options to add aliases. I tried renewing existing domain and also deleting Let's Encrypt SSL and replacing with self-signed and then re-installing Let's Encrypt SSL and still no alias options. I even uninstalled Let's Encrypt extension and re-installed. No joy.

For Forwarding domains too pls
(what's the big difference between a domain alias with 301 redirect and a domain set to hosting type forwarding anyway?)
We have our name in different TLDs redirecting to our main site, however when the other TLDs are accessed with https users get cert errors (for obvious reasons).

Any ETA on when this will be released?

:-/ waiting ...

What if I want to use a common SSL Certificate and not Let's Encrypt? Will this also be possible?

Azurel, my sarcasm obviously wasn't conveyed too well ;o)

(see also my previous response from March).

@Fish
Thats right, but that change nothing. Here are 53 that want this feature and with lets-encrypt extension its now possible, but not included yet since over a year and the admin have add a response this august. ;)

Azurel, the link you've posted was from this year. This request dates back 3 years.

That here is a dublicat of this request?

Use a SAN certificate on the main domain for this.

Let's Encrypt supports this by default:

https://community.letsencrypt.org/t/frequently-asked-questions-faq/26

"Can I get a certificate for multiple domain names (SAN certificates)?

Yes, the same certificate can apply to several different names using the Subject Alternative Name (SAN) mechanism. The resulting certificates will be accepted by browsers for any of the domain names listed in them."

Patience Bram. It's only been 3 years since this was requested.

Now google has announced that they're going to prefer https sites in their results the requests for https-sites has increased a lot. Plesk/Odin not supporting certificates on alias-domains is really hurting now.

+100, very usefull. Really need it for wordpress with multisite domain mapping.

This would be handy for multi-language Magento webshops (with separate TLD's for each language)

I need this too for a new product that uses same source code on one folder for multiple domains

I'd like this, too for our wordpress multisite with domainmapping.

The workaround for now is to create a subscription instead of a domain alias then changing in the customized conf :
/var/www/vhosts/system/[THE ALIAS DOMAIN]/conf/vhost.conf and vhost_ssl.conf
adding those lines:
DocumentRoot /var/www/vhosts/[THE MAIN DOMAIN]/httpdocs
SuexecUserGroup [THE MAIN DOMAIN's USER ID] psacln
<Directory /var/www/vhosts/[THE MAIN DOMAIN]/httpdocs>
AllowOverride All
