MS Gateway for Exchange 2013 - Any LDAP documentation?

[Jerry Benton]

Recipient verification is cached, so you server is not going to crash. It is not done via LDAP. I made a video a couple of years ago covering this topic here:

It might be better to write instructions for Exchange Power Shell cli which would probably be extremely similar in versions 2010, 2013 and upcoming 2016 version.   (2007 also had powershell but was architecturally a lot more like 2003 than 2010, so many of the commands are different)
