I was trying to install something and I changed the permission of the usr folder, and the usr bin folder. Everything started freaking out so I changed back the usr folder, but not the bin folder. Now I can't log in as that user anymore...It says session failed to start.

Also, while I was still in a session, the terminal would not start, and when I shut down the system it kept giving me the error "new session start detected" and would not stop.

How can I get that account back?

[edit]oops I just realized this is on the wrong thread....but maybe you can answer it anyway.....

When i log into the failsafe terminal, it says xterm: could not exec /bin/bash : Permission Denied

Disregard this post

I fixed the problem, for those having the same problem - make sure all users have read and execute access (i.e. chmod 755) to bin and bin/bash (or whatever login directory you use)
