What password is it asking for? yum?

[till]

It is asking for the password of the first user that you created, which is able to become root user under ubuntu.

So do you mean root? I enter the root password and I keep asking me for more passwords

It's not asking for the root password, but for the password of the user that is running sudo.

Following the thread, http://www.howtoforge.com/virtual_us..._clamav_centos

"Next we switch to this user

su vmail
sudo yum install libtool postgresql-devel gdbm-devel pam-devel expect openldap-devel"

Why does it need to sudo yum? yum is not a user in my CentOS at all.

[falko]

yum is not a user, but a command. Please see

man sudo
