Users are stored in two separate organizations corresponding to the two sites:
Example Bank is in the process of migrating users from Windows NT to Active Directory. Each employee has a Windows NT or Active Directory account. The migration of the users is based (in phases) on the employees’ last names. Every week Example Bank moves users whose last name begins with the next letter of the alphabet. Currently, the company has migrated employees whose last names begin with letters A through F.
For users who have Directory Server accounts, the Active Directory samaccountname attribute stores the uid. When a user account is migrated from Windows NT, the user keeps the same login. That is, the Active Directory samaccountname attribute of the new user is the same as the Windows NT USER_NAME attribute.
