When I set up a machine with CentOS 8, I used the "Enterprise Login" in the initial setup wizard to authenticate against my FreeIPA server. This worked fine, and I have no issues logging in with that initial user.
However, I am unable to use GDM or the console to login as any *other* valid user from FreeIPA. From GDM I get something like "Sorry, that didn't work" and "Permission denied" on the console. I've verified that the credentials are correct, and that I am able to manually get a ticket via kinit for one of those other users from this machine. With CentOS 7, I didn't have to do any additional configuration in this regard after the initial wizard.
Not sure whether this is a CentOS configuration issue or a FreeIPA one, but I figured I'd start here. I'm also not terribly familiar with FreeIPA, so I could be missing something obvious; but this worked without issue when the machine in question ran CentOS 7.
Can somebody point me in the right direction?
