A

. PowerExchange processes and passes user IDs and passwords to the operating system for authentication, as follows:

PowerExchange converts the user ID to uppercase.
PowerExchange checks whether the operating system is configured to handle mixed-case passwords. If so, PowerExchange passes the user ID in uppercase and the password in the case in which you entered it to the operating system for authentication. If not, PowerExchange converts the password to uppercase and passes the user ID and password to the operating system for authentication.

D

. PowerExchange converts user IDs and passwords to uppercase and then passes them to the operating system for authentication.

S

. PowerExchange converts the user ID to uppercase and leaves the password in the case in which you entered it. Then, PowerExchange passes the user ID and password to the operating system for authentication.

0

. PowerExchange does not require users to specify a valid operating system user ID and password and ignores any credentials that users supply. PowerExchange uses the userID under which the PowerExchange Listener or PowerExchange Condense task runs to control access to file resources. PowerExchange passes this user ID to the database system.

1

. PowerExchange requires users to specify a valid operating system user ID and a password or valid PowerExchange passphrase. PowerExchange checks these credentials when a PowerExchange task starts. Thereafter, PowerExchange controls access to file resources in the same manner as for option 0. For file access, PowerExchange uses the user ID under which the PowerExchange Listener or PowerExchange Condense task runs and passes this user ID to the database system.

2

. Provides the most specific level of security. PowerExchange requires users to specify a valid operating system user ID and a password or passphrase. PowerExchange checks these credentials when a PowerExchange task starts. PowerExchange Listener subtask processes run under the supplied user ID and password or passphrase. PowerExchange uses this user ID and password or passphrase to control access to PowerExchange files. PowerExchange also passes this user ID and password or passphrase to the database system for data access. PowerExchange uses security objects to control which users can run pwxcmd commands for a PowerExchange Listener or PowerExchange Condense process that are issued from a Linux, UNIX, or Windows system. The security objects also control which users can run PowerExchange Listener LISTTASK and STOPTASK commands that are issued from the SNDLSTCMD interface, the PowerExchange Navigator, or the DTLUTSK utility.

N

. PowerExchange does not use the selective sign-on file.

Y

. PowerExchange uses the USER statement with the ALLOW and IP subparameters in the selective sign-on file to restrict users who can connect to the PowerExchange Listener.
