Thanks for the reply Abhilash. Looks like I am missing something. Could you please help with the exact steps ?
Here are the steps that i have followed:-
1. Created a local user using vCenter Client (Via Local Users & Groups section )
2. This can not be added to a group since it's not supported from 5.1 onwards i suppose ?
3. Now created a role using vSphere Web client by selecting the CIM interactions
4. Using Webclient, Traverse to Manage --> Permissions. Add Permission. But "Users & Groups" dont list user created in 1st step!
Do you follow this procedure to assign a role for a specific user ?
