To determine whether
a user has an internal account, examine the Internal account section
of the user's Accounts page. If a user
has an internal account, their internal user ID is listed in that
location. In general, regular users do not have internal accounts.
Note: Internal accounts are visible
only if you have user administration capabilities or you are looking
at your own user definition.
Note: An administrator can enable
an internal account for a user by setting the Internal
Account option on the user’s Accounts page
to Create internal account.
