So I'm in a Linux OS class at the moment. We're playing around with ACLs, users, groups, etc. very rudimentary stuff.
I (clearly) messed something up, and I'm not sure what the issue is. Every time I sign in to my user, I get returned to the list of available users - if I type the correct password in. If I type an incorrect password in, I am simply told 'Sorry, that didn't work. Please try again.' as expected.
I haven't been able to find any solutions to this issue as a result of some basic googling, and I'd like to know if there's an answer other than wipe my machine and re-install CentOS.
