When I first read this, I misunderstood and thought you were talking about the ability to just use the family name when you enter a login name. If, for example, you are called "Dave Kelly" and you are the only Kelly in your SYSTEM directory, you can just use "Kelly" as a login name. This is already available for any of the Scalix clients. But, if you have an e-mail address of
dave.kelly@example.com, you cannot login as
kelly@example.com because there will be no exact match on the address. You can login as
dave.kelly@example.com though. This means that if you were to add an address to the user of
kelly@example.com, it would work.
If I understand correctly, you are asking for just the family name as an address/login template when new users are created. I can raise a feature request for this but I'd like to understand your requirement.
If you use just a family name for the authentication id or e-mail address, you cannot guarantee uniqueness, especially if a number of users are called Smith :-). We enforce a requirement that authentication ids and e-mail addresses *must* be unique for each entry in the directory. This prevents problems when mail is delivered or people are attempting to sign in.
