Root password reset!?

Hello, I'm quite new to Linux, and decided that since I'd be the only user on the system, I'd change the ownership of every single directory to myself using some command like this:

chowner aaron u+rwx /* -R -v

This seems to have changed my root password to something I don't know!

I'm using Suse Linux Professional 9.2.

Any suggestions?

I'm sorry to say, but that was very bad step You have done.
It would be better for You to simply use root account as Your account - but still, that would be bad choise also.

Your problem is security model under linux and some programs.
(Your suid binaries and programs used to authenticate users, are running now as aaron, which in turn denies access to some stuff by design)

I suggest You to boot Your system in single mode
(at boot You have to add 'single' parameter to the kernel name)
and do:
chown -vR root. /
passwd root (and entern new root password twice)

then reboot again, log in as root.
If You decide to use root account, just delete all others accounts.
If You stay with aaron, then 'chown -R aaron. ~aaron' (for each account in fact)

You may also need to revert some of Your binaries to its basic permissions as well...
