The following PSD1 file for schema attributes will result in a "unintended" update event;

Forest schema definition file

        Name = 'ms-DS-Key-Credential-Link-BL'
        AdminDisplayName = 'ms-DS-Key-Credential-Link-BL'
        LdapDisplayName = 'msDS-KeyCredentialLink-BL'
        OMSyntax = 127
        AttributeSyntax = '2.5.5.1'
        SingleValued = $False
        AdminDescription = $Null
        SearchFlags = 0
        ObjectClass = $Null
        IsDefunct = $False

Heya Andi,
thanks for the report. This is indeed an issue with the test, as the adminDescription setting is converted to string (an empty one in your case) and the property on the AD Object is $null when empty.
Will update this on the next release.
