do not allow attributeDefs with same name and different case

If you want to have attributeDefs with same name case-insensitive, set this in grouper.properties

To see if you have two attributeDefs with same name, run this query
 

select * from grouper_attribute_def gad1, grouper_attribute_def gad2

where gad1.id != gad2.id and 

lower(gad1.name) = lower(gad2.name)
