Comment 5 for bug 2078247

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) Install adsys;
4) Authenticate with an AD user using the \\ format (e.g. domain.com\\user)

After step 4, the user was authenticated, the username format was correctly parsed and all domain-related settings were applied.
