On a CentOS server where I'm logged via SSH as root, I do:

su otherusername

where 'otherusername' is the user name of another user, which exists.

It does nothing. After that, I'm still root. whoami returns root, any file I create belongs to root, that is, su just doesn't su.

However it does not give any error message. If I try to su with an invalid user name it does give an error message.

What am I missing??
