I would discourage enumeration especially if you're planning on a large
domain. The performance right now is not great. Moreover, the way the
trusted accounts are retrieved doesn't support enumeration at all

I would first try to remove the sssd caches because uid/gid renumbering
doesn't work great. If that doesn't help, please check the sssd logs.

By the way, 1000 is quite low and would most probably clash with local
accounts. I would strongly suggest to stick to ID numbers within the
configured ID range (ipa idrange-find)
