So, recently noticed an issue, which I think is new.
Fedora 32
sssd 2.3.0 - configured for AD, including sudo and autofs
I found that when Chef's "knife" command (from Chef Workstation 0.3.2) is run, the command takes a very long time to run, and in top sssd_be and sssd_autofs use a lot of CPU.
e.g.
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
17579 root 20 0 259196 32220 9340 S 28.2 0.4 0:18.62 sssd_autofs
17575 root 20 0 346320 25276 21672 S 24.3 0.3 0:16.54 sssd_be
Turned debug up to 9 for the autofs module and what looked apparent to me was the following, from one run of 'knife':
]# grep "not found in cache" sssd_autofs.log |wc -l
53144
# grep "not found in cache" sssd_autofs.log |head -n 20

Any ideas what could be causing this? Happy to provide sanitised config if required.
Cheers,
