Using platform password
Lotus Expeditor for desktop client provides a configurable and flexible platform login experience based on the Java Authentication and Authorization Service (JAAS). The IBM Sales Center is based on the Lotus Expeditor platform, and the default password dialog appears when Sales Center is launched.
When you initially launch the IBM Sales Center, you can set a password. This password is used every time you log into the Sales Center. The password is stored on the client machine in a secure keystore, and is not validated against the commerce server. Specifically, the platform password is saved in the user workspace (.metadata folder) in an encrypted format.
You can write your own password validation logic by writing extensions to the existing implementation using the custom logic configuration implementation.
