Handling special users during migration
During migration, for special user types with user identifiers (UIDs) below the number 20, Windows accounts are created such that the first nine characters of their Network Information Service (NIS) domain are appended to their UNIX-based user names to create their Windows account names. Their UNIX user names are unaffected. For example, if you migrate the root user from the domain physlab to Server for NIS, a new Windows user is created and named physlab_u_root . The UNIX user name is still root , and NIS queries from the physlab domain are not affected by the difference in names.
A group called root from such a domain, if migrated, will create a group called physlab_g_root .
