The administrative assignments for a user or security group are defined by the roles and security scopes assigned to that user or security group. The Windows Management Instrumentation (WMI) SMS_Admin class contains all the administrators defined in Configuration Manager. The security roles for an admin are in the SMS_Admin.Roles property and the security scopes for an admin are in the SMS_Admin.Categories property. Both of these properties expose an array of strings which correspond to the identifier of the role or security scope. Both properties are also marked as lazy and are read-only.

Important
Lazy properties are never retrieved with the class instance if the class instance was loaded from a query. The object must be directly accessed from WMI. Generally the WMI provider will supply a Get method that will accept a query path to the object.

To determine whether an administrator references a user account or a security group, check the SMS_Admin.AccountType property. This property value will be one or zero. Zero means that the account is a user, and one means the account is a security group.

To read the roles and security scopes of an administrator

  1. Set up a connection to the SMS Provider.

  2. Get an instance to a SMS_Admin WMI class that matches the desired administrator by using their identifier.

  3. Read the Roles and Categories properties.

Example

The following example pulls an admin directly from WMI and displays the role and security scope identifiers:

Visual Basic Script  Copy Code 
Sub PrintAdminScopesAndRoles(connection, adminId)
	Dim admin
	Dim item
	On Error Resume Next
	set admin = Nothing
	Set admin = connection.Get("SMS_Admin.AdminID=" & CStr(adminId))
	On Error Goto 0
	If (Not admin Is Nothing) Then
		WScript.Echo "Reading Admin: " + admin.LogonName
		WScript.Echo ""
		WScript.Echo " == Roles (" + CStr(UBound(admin.Roles) + 1) + ") =="
		For Each item In admin.Roles
			WScript.Echo " = " + item
		Next
		WScript.Echo ""
		WScript.Echo " == Security Scopes (" + CStr(UBound(admin.Categories) + 1) + ") =="
		For Each item In admin.Categories
			WScript.Echo " = " + item
		Next
	Else
		WScript.Echo "Admin with id " + CStr(adminId) + " not found."
	End If
End Sub
C#  Copy Code 
public void PrintAdminScopesAndRoles(WqlConnectionManager connection, int adminId)
{
	IResultObject admin = null;
	try
	{
		admin = connection.GetInstance("SMS_Admin.AdminID=" + adminId.ToString());
}
	catch (Exception) { }
	if (admin != null)
	{
		Console.WriteLine("Reading Admin: " + admin["LogonName"].StringValue);
		Console.WriteLine("");
		Console.WriteLine(String.Format("== Roles ({0}) ==", admin["Roles"].StringArrayValue.Length.ToString()));
		foreach (var item in admin["Roles"].StringArrayValue)
			Console.WriteLine("= " + item);
			Console.WriteLine("");
			Console.WriteLine(String.Format("== Security Scopes ({0}) ==", admin["Categories"].StringArrayValue.Length.ToString()));
		foreach (var item in admin["Categories"].StringArrayValue)
			Console.WriteLine("= " + item);
}
	else
		Console.WriteLine("Admin with id " + adminId.ToString() + " not found.");
}

The example method has the following parameters:
