You need a Kerberos ticket to run IPA commands. The help command may retrieve data from the server because it is a thin client, hence the need for a ticket even for the help commands. The options may have changed on the server.

For quick questions like these it is preferable to use either IRC irc://irc.libera.chat/#freeipa or the freeipa-users mailing list.

We prefer to use the ticketing system as a bug tracker, not end-user support.
