[Freeipa-users] ipa command always takes 30 seconds

I've installed freeipa on Ubuntu 18.04. The Web UI as well as kinit and logging in via ssh work fine. There is no noticeable delays. But the "ipa" command from the command line always takes 30 or 60 seconds. For example: ipa user-find admin will take 30 seconds. Creating users (using "ipa") takes 30 seconds, etc. (This is after logging in via kinit.) I have not turned on debug yet but the log files are not helping so far. Any ideas or suggestions? I have tried with a DNS and without a DNS. With the DNS I've tried various forwarding options. Nothing I've tried has had a positive effect. Currently I have a DNS with a forwarder to the original DNS server. The Kerberos realm and DNS domain are more or less just made up -- if that matters. Thank you, Perry Smith
