Comment 5 for bug 2078246

I'm sorry for not commenting about the executed test plan. Let's fix this!

The test plan was executed for Jammy (22.04) and I confirm it was successful. The package version used for the tests is the one proposed, as can be seen by the output of apt-cache policy:
adsys:
  Installed: 0.14.2~22.04
  Candidate: 0.14.2~22.04
  Version table:
 *** 0.14.2~22.04 500
        500 http://archive.ubuntu.com/ubuntu jammy-proposed/main amd64 Packages

The following steps were executed:

1) Create a fresh VM with Ubuntu 22.04;
2) Join an active directory domain (created for test purposes);
3) Edit the SSSD configuration file (/etc/sssd/sssd.conf), ensure that the domain string under "domains" in the SSSD section and that the domain-related section have mismatched casing (e.g. domains=domain.com and [domain/DOMAIN.COM]) and restart the SSSD service;
4) Install adsys;
5) Authenticate with an AD user that belongs to the domain;

After step 5, the user was authenticated and the domain-related settings were applied.
