I'm stumped by this (and how I might have done it). On my Fedora 15 server, now whenever I login (even with root user) after I type my username I get an "Access Denied" message, but then I can enter my password and login normally. This happens with both root and regular users. Where in the login procedure, could the problem lie?
login as: tom
It's really annoying. How can I fix this? Thanks.
