No SSH access for vSphere 4.1

After a upgrade to VMware vSphere 4.1 I couldn’t SSH to the Service Console. First I thought the password wasn’t correct, but after checking to login on the console directly I noticed that the password is correct. When I enabled rootlogin in the /etc/ssh/sshd_config -> permitrootlogin yes, I could login as root through SSH, so SSHD was working. So I must be a new security feature in vSphere 4.1. Then I changed the vSphere permission in the vSphere client to for my user to Administrator. After this I was able to SSH to the server. I’m haven’t had the time to check witch feature is responsible for this but I’m going to.
