Hi, I would like to check if the users firstname starts with a Capital, if not give an error. Is this possible with regex in the validation fields of the attribute/binding? and how ? I've only seen things like the employeeType attribute where the regex specifies the exact values... Thx in advance!

go to Administration -> Schema management -> Bindings for user object click on First name, select Validation tab and enter your regexp there. something like ^[A-Z]

Ok thx that worked. My only problem is I can't get it to work on a multivalue field... is that correct ?

I don't think it's supported, although MS guys should know the answer
