Hello, I'm new user in linux community. I have installed in my computer mandrake linux 10.0 Sometime ago it was working normal without problems. After that I changed the root password, always that I want to change something in the configuration of the system, I run su from other user (vladimir). But the system says 'invalid password'. I tried the old, and new password, but it doesn't work I have to logout, and login with root to change some configurations. Anyone could help me!! thank you Vladimir - : send the line "unsubscribe linux-admin" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
