[+] Description of problem:
 - when the root ad domain is not listed in ad_enabled_domains, sssd will mark the subdomains as offline

[+] Version-Release number of selected component (if applicable):
 - sssd-1.16.5-10.el7_9.8.x86_64

[+] How reproducible:
 - sometimes - the failure occurs when sssd tries to retrieve trust information from the root domain

[+] Steps to Reproduce:
1. configure an ad forest with two or more domains
2. enable only the ad subdomains in ad_enabled_domains
3. monitor sssd to see subdomains marked offline

[+] Actual results:
 - all domains are marked offline and sssd fails to perform user lookups for a certain period

[+] Expected results:
 - root domain being disabled is treated as normal and sssd keeps all subdomains online

[+] Workaround:
 - list ad root domain in ad_enabled_domains

Verified against sssd-2.6.1-1.el8.x86_64. 

Automation is almost finished, tested manually.
