Evening,
I am attempting to get apache authenticating with IPA but not sure why its
rejecting the keytab. I have even recreated the keytab a number of times
but this isn't making any difference. To make sure the problem isn't
anywhere else, I briefly used a httpasswd file and it worked fine, so
confident it has to do with apache IPA integration. Does anybody notice
anything wrong with the setup below?
