WebSphere Commerce users can access storefronts by virtue
of having the role of Registered Customer in
the organization that owns the store, or in any organization above
it. The roles a user has access to during registration are defined
within the MemberRegistrationAttributes.xml file.
About this task
By default the MemberRegistrationAttributes.xml file
is set up to give access to only the store where the user is registering.
If there are two stores, store A and store B, registered customers
for store A are assigned to organization A, and have no access to
store B, which belongs to organization B. To allow registered customers
to access all stores, you must change the Register Customer role context
in the MemberRegistrationAttributes.xml file.
Within an Extended Sites model, create all stores should be created
under the Extended Sites seller organization.
