[SOLVED] root inaccessible even after password change
Posted: 2016/03/09 13:46:24
I have several CentOS-6.x systems for a sensitive network.
I used to be able to access the root account, even through the GUI logon screen, until months ago. Something happened, and I believe it was after a patch update to all of the systems (including my server referenced in my posting from last night).
I do have a GRUB password set to the same value for my 6 workstations and 1 server.
I can only, however, gain access to root on the 6 workstations when in single-user mode; but the server I cannot access through GRUB at all (refer to last night's post for the details).
After gaining access to the GRUB menu, after hitting 'p' and being prompted for and successfully passing the password challenge to use the GRUB menu, I add the value 'single' to the end of the vmlinuz line.
I get root access in single-user mode, and I successfully alter the root password on all 6 workstations (only the workstations) but at the Gnome Desktop, I still cannot gain local access to root.
PLEASE help me, I am in dire straits with this system.
