Hi,

Let's Encrypt is a trusted public CA; you can only acquire leaf
certificates for TLS servers from Let's Encrypt.  You cannot acquire
a CA certificate from Let's Encrypt.

The script you found must be for acquiring service certificates from
Let's Encrypt, for IPA-enrolled hosts/services.  I do not know if it
works with CentOS 7, but if it works with FreeIPA 4.x on Fedora, it
will probably work with ipa-4.x on CentOS 7.

Thanks,
Fraser

Günther,

The script from github works fine 
(https://github.com/freeipa/freeipa-letsencrypt).  We use it in production 
on CentOS 7.  Keep in mind the script by will only configure the 
certificate for the web ui, and not LDAP/s.  You will need a separate 
process for that.

Hello,

after the mistake with Startcom CA (Class 3), now I look for a new
Certificate..

Is it possible and functional to install a Letsencrypt CA on a IPA-Server?

I have found a script on "github" to install a Letsencript CA for FreeIPA
(fedora), but can any tell me is this working with CentOS 7.(3).

Thanks for a answer,

Hi,

Instead of using the Let’s Encrypt thing on the IPA server itself, I often just 
use it on a reverse proxy. This way the end-users see the verified CA and 
FreeIPA can keep doing it’s business.
I tried to use ACME on the IPA server in the past, but it wasn’t very well 
integrated and caused problems. Since only web-facing elements benefit from 
external CA signed certificates (for users that access it but don’t have the CA 
on their machine), it doesn’t actually need to be integrated with the rest of 
IPA.
