su refuses to accept root password
I've been trying to set it up so I won't have to run as root all the time (changing permissions/ownerships, setting up groups, etc.), but for no reason I can find, when logged in as a user, su won't accept the root password, which I know works, because I can log in as root without any problems. I've tried using to passwd to reset my password, but it still won't su. I can su from root to something else (which doesn't require a password), but the reverse won't work whether I put in the right password or not, no matter how many times I try. It does this under X, console, anything, even trying to run root access only GUI configs with the GUI'd password entry, it just won't work
I'm running Gentoo (~x86, stage2).
