Locked out by Authentication?
RH 8.0.
For reasons that are not immediately relevant, I changed Authentication settings through the GUI, including turning on Kerberos. I may have made other changes in Authentication as well, I can't remember. My thinking at the time was... "I can add the additional authentication methods, and nothing else will really change". Brilliant.
When I rebooted the system I found one significant change. I have 2 logins plus root on this machine, and none of them will work either within the GUI or from the prompt. (I have managed to make my computer very secure, even from myself. From one perspective, this may be a good thing as it prevents me from making any other dumb changes to my system.)
Does this make sense so far?
Here is possibly some good news. I can still access GRUB with my root password. So, if I knew what to do with it, I probably could make a lot of changes to my system, maybe even break in. Suggestions welcome.
Thanks,
Jeff
