I have a list of user's security identifiers and I need to get a list of userPrincipalName's... is there any way that I can get it without loading up the users DirectoryEntry and pulling in the userPrincipalName property?

I need the most efficient method possible because this is done a lot

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
