Planning to use computer roles

Because computer roles provide you with a great deal of flexibility for defining access rights, you might want to do some planning before you create new computer roles. For example, before you create a computer role you must know the criteria you want to use to group computers into one or more Active Directory security groups. You must also identify the users who will have a common set of access rights based on the computer grouping.

At a high-level, defining a computer role requires the following:

  • Identify computer roles you want to define.

    Decide on the attribute the computers in a particular group share. For example, you can use a computer role to identify computers in the web farm, that host specific applications, or serve a specific department.

  • Identify the users for the computer role and create Active Directory groups for them.

    You might need multiple groups because different sets of users have different access requirements. For example, if you are creating a computer role for a set of Oracle servers, you might need separate Active Directory groups for database users, database administrators, and backup operators.

  • Identify the role definitions each set of users should be assigned.

    You might need to create specific access rights and role definitions for different sets of users. For example, if you are creating access rights for database users, database administrators, and backup operators, the database users may be able to use the predefined UNIX Login role, while administrators need permission to run privileged commands, and backup operators might be assigned a limited set of commands in a restricted shell.
