Rob, I googled a bit more, and I think I misunderstood what you meant. You're right,
when running 'ipa config-mod --enable-sid --add-sids', I *do* get an error in
'/var/log/dirsrv/slapd-EXAMPLE-COM/errors', I do see the following:
[19/Sep/2023:21:33:28.535278863 -0400] - ERR - sidgen_task_thread - [file
ipa_sidgen_task.c, line 194]: Sidgen task starts ...

I'll try to figure out how to correct this.
Thanks.
