Vagrant password

[#1]

I am following these instructions http://hortonworks.com/blog/building-hadoop-vm-quickly-ambari-vagrant/ for setting up a cluster using vagrant. When I try to SSH to the VM, I get prompted for password. The default vagrant password "vagrant" doesn't work. What can I do to bypass the password requirement?

Also if you use vagrant to provision VMs please avoid using VM GUI as you can accidentally disassociate your VMs from vagrant keys and also cause vagrant lose ssh permission. I had that happen to me and restoring access is not intuitive.

Thanks @Ravi Mutyala and @Artem Ervits. After getting stuck I ended up starting over using instructions on Apache wiki. I'm not sure what exactly was different but no password-related problems.
