Manager user cannot create Server

Hello,

We have just deployed a BigIP DNS platform, which will be managed by different groups of people with different privileges.

The 'Administrators' group of users should take control all the features, and they will be able to execute all commands and actions. The 'OperationsManager' group users will take charge of most usual actions, like create new services, WideIP's, Pools and so on.

So I have created those 'Remote Role Groups', because we use a TACACS+ Server to authenticate users, and associate different roles (Administrator and Manager) to these groups.

I have observed that 'Manager' users can create WideIPs, Pools, iRules, Monitors.... but they cannot create/delete/modify Servers, nor VirtualServers. Is it a bug? Do we need to assign this users to a different role? Which one?

Thanks for your support.
