I have been looking for documentation on the current list of defined roles and their properties. I would like to know what are acceptable entries for specific properties. I have been able to figure some of this out but having it documented would be beneficial for everyone. An example of what I mean is the CaRoot Role. It has a long list of properties but there is no definition of what are valid values for many of them. Ie. ValidityPeriod= does this take Years or can it accept Months/Days. What is the format if it does?
Another example is InstallWebRole= I had originally tried 'True' but it actually seems to only accept 'Yes' or 'No'
So does DoNotLoadDefaultTemplates= also only accept 'Yes' or 'No'?
