Users are deleted from default groups in identity feeds

During an identity feed, users can be inadvertently deleted from the default groups that are associated with the customized groups.

When performing an identity feed, always specify that a user has membership in both a customized group and the default group of the same category. For example, a user who is a member of a customized group must also be a member of the default group of the same category or processing results are unpredictable. If the incoming identity record for a user initially indicates membership in a customized group, the product includes the user as a member of both the customized group and the default group of the same category. IVIG interprets a subsequent identity feed that includes the same user as a modification of the existing user. If the subsequent identity feed specifies the user has membership in the customized group, but not in the default group of the same category, the software removes the user from membership in the default group.
