The key indicates that this application is integrated with Privilege Management Infrastructure (PMI). You must log into such applications with the same UserID (RACF ID) and Password as you would use for Employee Central.
Your PMI password is the same as your Windows password. When you change your Windows password your PMI password is synchronized with Windows.
If you change your PMI password, your PMI password will no longer be in synch with other P-Synch platforms until the next time you change your Windows password.
