UNIQUE MEMBER NAMES

UNIQUE MEMBER USERNAMES

By default, usernames are unique only within an individual site. Prior to NATS version 4.0.69.1, there were two configuration settings that could affect username uniqueness.

• UNIQUE_USERNAMES Require usernames on the join form to be unique across all sites. If there is a match, the user must pick a new username.
• XSELL_UNIQUE_USERNAMES Requires cross sale usernames to be unique across all sites. If there is a match, the new xsell username is automatically renamed.

On NATS version 4.0.69 and greater, these variables have been replaced with a new variable --UNIQUE_MEMBER_NAMES-- with 9 options . The first four of these options replicate existing functionality from older versions:

• only unique within site -- this is the default setting.
• unique across sites for joins and xsells -- this replaces selecting both UNIQUE_USERNAMES and XSELL_UNIQUE_USERNAMES
• unique across sites for xsells but site specific for joins -- this replaces selecting only XSELL_UNIQUE_USERNAMES
• unique across sites for joins but site specific for xsells -- this replaces selecting only UNIQUE_USERNAMES

The second five options allow for new functionality -- letting usernames be unique across sites, but allowing exceptions if the email is also a match

• unique across sites for xsells and unique unless emails match for joins
• not unique across sites for xsells and unique unless emails match for joins
• unique across sites for joins and unique unless emails match for xsells
• not unique across sites for joins and unique unless emails match for xsells
• unique across sites unless emails match for both joins and xsells
