[ic] Use E-Mail Address Instead Of Username For Login

Can't help you with 4.8 other than point you to search for "unique"
in recent list postings at Google.

With 4.9, there is a new indirect login capability. It automatically
checks that for uniqueness, and allows you to assign a customer number 
automatically. To use it, you need in catalog.cfg:

UserDB    default    indirect_login  email
UserDB    default    assign_username 1
UserDB    default    sql_counter     userdb:custno

You can omit the sql_counter parameter if you don't want to use 
a sequence in your database to create the user number. Otherwise,
create a sequence as described in the sql_counter docs (4.9) for
the counter tag.

(
    For Postgres, it is as easy as:

	create sequence custno;

    For Mysql, you have to create a one-field custno table and make that key field
    AUTO_INCREMENT.
