thanks Fred...

valid? indeed works and so does errors and yes, it obviously uses ActiveModel now but since it's LDAP but not user friendly, it's not for the uninitiated.

@group.errors is a mess and @person.errors - fahgettaboutit and will not be useful to someone trying to use the application so I ended up using .to_a.uniq to toss out the dupes...

I finally just worked it out a minute ago with this (in my Person model)

flash[:error] = @person.validate['base'].to_a.uniq.join("<br />")

apparently have to use .html_safe in my view to view the flash[:error] and it's reasonably friendly now.
