A.3 User Principal Logon Name
The UPN logon name consists of a user name followed by an “@” sign, then a configured
logon name. Instead of supplying the FQDN, the user supplies a name that has been
configured on the Global Catalog, and the domain controller does a lookup on the Global
Catalog to find the FQDN that is associated with the configured name.
This is useful for standardizing user logons when there are multiple sub-domains in an
organization. If a user changes sub-domains, the administrator can simply re-configure the
UPN to point to a different FQDN, and the user then retains the original logon name.
User Principal Names are only available in Native Mode.
