Most probably duplicate of bz 1884912 (and bz 1773488)

Hi Sumit/Alexey,

On case: 03292814 cus is not able to see any segfaults after adding `ad_enabled_domains`

Comment 13 Alexey Tikhonov 2022-09-16 15:01:18 UTC

bz 2052918 and https://github.com/SSSD/sssd/issues/6007 might be relevant (or not).
