I have my system on dual boot (win7 and RHEL 6).
I have 2 user account on RHEL 6. A normal user and a root user. I put passwords of both accounts same. It was working fine from 5 6 days. Yesterday I installed ntfs-3g to use NTFS drives in RHEL. It worked fine too. Now today's morning when I started my laptop, I login through the normal account, worked fine. Then I accessed NTFS drive, it asked for authentication, I gave root's password but it said that the password is wrong.
I will change the root's password from single user mode. But I just want to know why did this happen? How it changed automatically?
PS: No one else accessed my laptop.
