vSphere vCenter read-only role doesn't seem to work

Hi everyone,

We used a user with read-only role assigned in a vSphere 5.1 vCenter to monitor the vSphere environment (with Check_MK / Nagjos) and to backup the VMs (with Quantum). Since we installed vSphere 5.5 vCenter and VMware ESXi 5.5, the same user identically defined, can't monitor or backup the environment anymore. We needed to give him full permission.

Was could be the problem? Thanks a lot for any help!

Have the roles been reset, that you previously created ?
Davy ParidaensCommented:
You need to have to create the user on Vmware ESXi host as in the vCenter

@Andrew Hancock: It is a completely new vCenter and new ESXi server. So these are the new default roles from vSphere.

@Davy Paridaens: How do you mean that?

Thanks for your help.

So I need to create the same user (with same password) on each esxi which was created in vCenter before?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
I've never seen a read only user, being able to backup VMs.

We normally create an Admin Backup Role, and secret password.
Davy ParidaensCommented:
Like Andrew said read only users have only read not execute privilages.
And yes you need to recreate the users across the ESXi hosts and vCenter.
