create a smart group based on User Account Type?

@walt The following Extension Attribute code may prove helpful:

#!/bin/sh

loggedInUser=$(stat -f%Su /dev/console)

if [[ $( /usr/bin/dscl . read /Users/${loggedInUser} OriginalAuthenticationAuthority 2>/dev/null) ]]; then
    echo "<result>$loggedInUser is an Active Directory Mobile account</result>"
else
    echo "<result>$loggedInUser is a Local Directory account</result>"
fi

exit 0
