Hello there!
Ubuntu 18.04 (and previous ones) works just fine In Ubuntu 22.04 I'm trying to execute ipa-client install but it fails with:
root@fisica75:~# ipa-client-install This program will set up IPA client. Version 4.9.8

There is no Hostname mismatch for the server certificate. It has been working just fine for years with multiple distros as clients. I can access the website with the same URL and cert is just fine.
Any ideas? Thanks!

The error message is pretty clear and comes out of openssl. Can we see the web server certificate from that host? Can you confirm that the host the client connected to is actually this host (e.g. DNS or /etc/host issues)?

Here's info obtained from the same client using openssl, you can se that subject CN is fine.

Thanks, this is very helpful. I wonder if the same s_client and curl commands work from the Ubuntu 22.04 machine or if they'll fail in the same way.
The cert lacks a DNS SAN for the hostname. I suspect this may be the issue (using the CN has been deprecated forever but was still allowed in most libraries). What version of OpenSSL is on 22.04?

[solved] As stated, SAN was missing in my certificates I resubmitted my certificate at the ipa server adding SAN with:
# getcert resubmit -i <certmonger_request_id> -D $(hostname)
Now I can execute ipa-client-install without a problem! Thanks!

the web server certificate from that host? Can you confirm that thehost
the client connected to is actually this host (e.g. DNS or /etc/host issues)? rob-- Gustavo Berman Sysadmin - Gerencia de Física - Centro Atómico Bariloche - CNEA

Same here on Fedora37 After installing Fedora37 and freeipa-client 4.10.1 I try to connect the server using: ``` ipa-client-install --mkhomedir --force-join ``` and fail with the error
``` cannot connect to 'https://<IPASERVER-FQDN>ipa/json': [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: Hostname mismatch, certificate is not valid for '<IPASERVER-FQDN>'. (_ssl.c:992) ```
1. The server uses a self-signed certificate, and the CN is matched the <IPASERVER-FQDN>, 2. The same process works as expected on other clients running freeipa-client 4.9.6 (with Fedora34)
@Gustavo, did you manage to deal with it?
FREEIPA-CLIENT: 4.10.1 FREEIPA SERVER: 4.6.8 API_VERSION: 2.237
oops, I replied to the first post and missed the whole thread, I see it's a DNS SAN issue I'll try adding it
