This option specifies whether standard, integrated, and Kerberos logins are permitted. One or more of the following login
modes are accepted (the values are case insensitive):
Standard logins are permitted. This is the default setting. Standard connection logins must supply both a user ID and
password, and do not use the Integrated or Kerberos connection parameters.
Integrated logins are permitted.
Kerberos logins are permitted.
This is equivalent to specifying Standard,Integrated.
If you specify multiple login modes, the database server allows all the specified modes.
Setting the login_mode database option to not allow Standard logins restricts connections to only those users or groups who
have been granted an integrated or Kerberos login mapping. Attempting to connect with a user ID and password generates an
error. The only exceptions to this are users with DBA authority.
You can specify multiple values in a comma-separated list. This list cannot contain white space. For example, the following
setting allows both standard and integrated logins:
SET OPTION PUBLIC.login_mode = 'Standard,Integrated';
If a database file is not secured and can be copied by unauthorized users, the temporary public login_mode option should be
used (both for integrated and Kerberos logins). This way, integrated and Kerberos logins are not supported by default if the
file is copied.
