I can login as myself into our linux box, but when i try to SU, I am told I have a bad password.
I am pretty sure I am locked out of SU. I dont really even have a starting point on how to troubleshoot this, as I am a Microsoft guy. I have researched, but I cant understand half of the suggestions (and how they apply to our specific system).
Can anyone suggest some routes to take to regain SU rights?! I know I am using the correct password.

I was working on the machine yesterdsay, and SU worked fine.
Wondering if this isint a password issue, and possibly a grouping or r/w issue...or does ROOT always stay in the root group?
Yesterday I created a new group, and added 2 new FTP users that I created. I create FTP users all the time, its the group creation and such that was new to me. In the end I got it to work as planned, but since I was messing around with groups maybe I did something?
SU was working when I left the office yesterday, but I know SU didnt just magically stop working for no reason.
Would single user mode be a good place to start (http://linuxgazette.net/1
Or is there any other information I can look at to direct me out of this before we go that route?
thanks
fixed!
I followed the steps I linked to in the website above. Perfect!
Booting into single user mode from GRUB
Follow these steps to reset the password when using GRUB:
Reboot the system, and when you are at the selection prompt (See Fig. 2 below), highlight the line for Linux and press 'e'. You may only have 2 seconds to do this, so be quick.
This will take you to another screen where you should select the entry that begins with 'kernel' and press 'e' again.
Append ' single' to the end of that line (without the quotes). Make sure that there is a space between what's there and 'single'. If your system requires you to enter your root password to log into single-user mode, then append init=/bin/bash after 'single'. Hit 'Enter' to save the changes.
Press 'b' to boot into Single User Mode.
Once the system finishes booting, you will be logged in as root. Use passwd and choose a new password for root.
Type reboot to reboot the system, and you can login with the new password you just selected.

with command 'su' (just two letters) you are switching to user root - you should provide root's password.
Are you able to login as root directly (ie. from console - from x server, you can get to text console be pressing ctrl-alt-f1/f2/f3.../f6. To move back to your xserver, press alt-f7).
Do you have sudo command?
Try to run ie.: "sudo id" (without "" of course) and post here an output. If you are asked for password, provide _your_ password, not the root one.
