Persistent verification enables two LUs to verify the initial conversation on a session and to assume that future conversations are verified for the duration of the session or until the user ID is signed off. This communication is shown in Figure 1.

1. LUA requests a conversation with LUB. The FMH-5 includes a user ID, a password, and an indication that the user ID is signing on to LUB.

   When the current transaction completes, the conversation is deallocated normally.

2. At a later time, LUA requests another conversation with LUB for the same user ID. This time, the FMH-5 contains the user ID and the already-signed-on indicator.
