Hi Tobias, Thorstein, and anyone who is after a backport of these patches,

I have completed backporting the below patches to the Bionic and Focal adcli and sssd packages, and I am looking for some help with testing. If you have some spare time, a Windows Active Directory server available, and some test Ubuntu machines, I would really appreciate help ensuring these test packages work as  expected.

Source code / debdiffs for the test sssd and adcli packages are below if you are interested:

Focal:
sssd: https://paste.ubuntu.com/p/JCVcV26RS2/
adcli: https://paste.ubuntu.com/p/RSqSWdCYQH/ 

Bionic:
sssd: https://paste.ubuntu.com/p/vcyYnjVdg7/
adcli: https://paste.ubuntu.com/p/SVpHZc59pq/

Please note, these test packages are NOT SUPPORTED by Canonical, and are for
TEST PURPOSES ONLY. ONLY install in a dedicated test environment.

Instructions to install (on a bionic or focal system):
1) sudo add-apt-repository ppa:mruffell/sf294530-test
2) sudo apt update
3) sudo apt install adcli sssd
4) sudo apt-cache policy adcli | grep Installed
Installed: 0.9.0-1ubuntu0+sf294530v20201013b1 // for focal
Installed: 0.8.2-1ubuntu0+sf294530v20201019b1 // for bionic
5) sudo apt-cache policy sssd | grep Installed
Installed: 2.2.3-3ubuntu0+sf294530v20201012b1 // for focal
Installed: 1.16.1-1ubuntu1.6+sf294530v20201021b1 // for bionic

Please let me know if these test packages work as expected in regards to the "ad_use_ldaps" flag, or if you run into any problems.
