Description of problem: Local user accounts are unable to login to VSFTP when the daemon is correctly configured and their shell is set to Bash. The problem is resolved when the line "/bin/bash" is added to "/etc/shells" or VSFTP is configured to avoid this requirement (not a recommended configuration!). Solution: Add the missing line to "/etc/shells" in the next update of the package.
Please run yum reinstall bash ... there was a buggy bash update. *** This bug has been marked as a duplicate of bug 752827 ***
