Suppress Active Directory Information from People Control
Currently, if a SP 2013 list includes a Person or Group column configured to Choose From All Users, a Nintex form for the list will render the column as a People control. At run time, the People control will display the underlying user’s AD Domain and Login if you hover over it. This may be a security risk.
Can we add a Control Setting in Nintex Forms that enables us to hide the AD information (and perhaps default this setting to Yes)?
Please refer to Support Case #00067767 "RE Person Column" for additional details.
Thanks

Thanks for your suggestion.
I will update this idea if there are any updates to share.
