ADUser: Unable to enter Debug Mode

[johlju]

Details of the scenario you tried and the problem that is occurring

There are issues with entering debug mode (using Enable-DSCDebug -BreakAll) when a default value for a parameter is derived from a function or another parameter.

This issue has been reported both in issue dsccommunity/SqlServerDsc#448 and in issue dsccommunity/ComputerManagementDsc#231.

These lines will probably cause an issue entering debug mode.

Verbose logs showing the problem

Not available - this issue is proactive.

Suggested solution to the issue

Remove the default value from the parameter and instead add the following code to the start of each function needing to set this default value.

if (-not $PSBoundParameters.ContainsKey('CommonName'))
{
    $CommonName = $UserName
}
