Rational® DOORS® can use system user names to log in to the Rational DOORS database. Your system user name is the name that you use to log in to your computer, for example your Windows user name.
If system user names are enabled for Rational
DOORS login, it is important to enter the system
user name of each user in their user account. Rational
DOORS uses the system user names that are
entered in the user accounts to determine whether there are identical system user names.
- Users who have identical system user names must type their Rational
DOORS user name when they log in to the
database
- Users who have unique system user names do not need to type their Rational
DOORS user name to log in to the
database.
All system user names are unique within a single Windows domain.
Your system user names might not be unique if users are in two or more Windows domains or you have both Linux users and Windows users.
If there is any possibility that your users might not have unique system user names, and
you want to enable system user names:
- Make sure that your Rational
DOORS database uses passwords.
- Make sure that every Rational
DOORS user account record has a
System Username.
- Do not ignore warning messages that a user account record does not have a
System Username.
CAUTION:
For security reasons, use passwords along with system user names. If
you do not use passwords, the Rational
DOORS login screen is not displayed, and the
database explorer opens.
Restriction: - You cannot use system user names when you are using Rational Directory Server for user administration
in SSS mode.
- An interoperation server can be used with a database that is configured for
system user names; however, Rational DOORS Web Access does not support system
user names.

Judy Brown is using Windows 7. Her system
user name is Judy, and this user name is recorded in her Rational
DOORS user account. No other Rational
DOORS user has the same system user name, so
when she starts Rational
DOORS, she does not need to type her Rational
DOORS user name.
Now you create an account for Judy Smith, who is using Windows 2008, and whose system user name is also Judy.
You enter her system user name in her user account.
When either Judy Brown or Judy Smith start Rational
DOORS, they must type their Rational
DOORS user name on the login screen, because
there are now two users with the same system user name.
If you forgot to enter the system user name for Judy Smith in her user account and
ignored the warning message, Rational
DOORS cannot tell that there are two users
with identical system user names. When Judy Smith logs on to her computer and runs
Rational
DOORS, her system user name is matched with
the user account for Judy Brown.
