Logging on to a host
To log on, left-double-click on the host entry or right-click on the host entry and select
Open Host from the pop-up menu. If you are working with a domain group, left-double-click on
the domain group or right-click on the domain group and select Open Group from the pop-up
menu. When you open a domain group in the TKE main window, you must log on to all hosts that are to
be accessed within that group.
Note: Before attempting to use a user ID that has been
configured to use Multi-Factor Authentication (MFA), see TKE RACF Identity Token Support and Multi-Factor Authentication (MFA).
The Logon window is displayed for the host logon.

Enter your RACF-defined TSO/E host user ID and password. Your RACF-defined TSO/E host user ID is the user ID of the TKE administrator.
If z/OS V1R7 or higher is installed, mixed case passwords are supported by RACF. If the Enable
Mixed Case Passwords check box is enabled on the Log on to Host window, passwords are used as
entered and are not automatically folded to uppercase. You must enter your password as it was
defined in the RACF database. If your system does not support mixed case passwords and you check the
Enable Mixed Case Passwords check box, you must enter your password in uppercase or you get The
password is incorrect
error.
Note: If your TSO/E password has expired, the message The
password has expired. Change password from TSO is displayed.
Change your password and perform the logon again.
