You may encounter a problem entering text into a password field on Japanese or other Asian language Linux operating systems, such as Red Hat Enterprise Linux (RHEL) 5. This technical note describes how to solve the problem.
The SCIM input method editor (IME) contains a bug that diverts focus away from the password field. As a result, keystrokes never reach the password field handler.
To solve the problem, modify the SCIM configuration as follows:
Change false to true so that it reads /FrontEnd/X11/Dynamic=true.
