I have tested this change and it doesn't solve issue #644. The ServiceName is still mapping to the samAccountName according the error message I got.

This is my test scenario:

Configuration ADManagedServiceAccount_CreateManagedServiceAccount_Config
{
    Import-DscResource -Module ActiveDirectoryDsc -ModuleVersion 6.2.0

    Node localhost
    {
        ADManagedServiceAccount 'ExampleStandaloneMSA'
        {
            Ensure = 'Present'
            ServiceAccountName = 'MyMoreFancyServiceLongName01'
            SamAccountName = 'Service01'
            AccountType = 'Standalone'
        }
    }
}

And this is the error message I got:

    Import-DscResource -Module ActiveDirectoryDsc -ModuleVersion 6.2.0

    Node localhost
    {
        ADManagedServiceAccount 'ExampleStandaloneMSA'
        {

            SamAccountName = 'SamService01'
            AccountType = 'Standalone'
        }
    }
}

The result is:

When looking to the attributes of the created Managed Service account the values are as following:

cn:               Service01
distinguishedNam: CN=Service01,CN=Managed Service Accounts,...
name:             Service01
sAMAccountName:   Service01$

In summary, the definition of the SamAccountName property has no effect.

@Antiohne, thank you for testing this! I haven't been testing with an account created by DSC (my use case is an account created by an external installer invoked by xPackage). It's a bit of a giant gaping hole that I need to work out..

Thanks,
JP2

This PR needs integration tests.

Have you tested this change through the full lifecycle of an ADManagedServiceAccount object and this additional property? i.e. addition, modification and deletion of an ADManagedServiceAccount with and without this property, and addition, modification and deletion of this property. This must be a non-breaking change to current usage of this resource.
