The already-verified indicators are used when a conversation request is being passed from one application program to another. The LU that receives the FMH-5 can use the user ID and password to validate the conversation request. If the conversation request is valid, the LU can remove the password field from the FMH-5 and pass the conversation request to another LU. This communication is shown in Figure 1.

1. LUA requests a conversation with LUB.
2. LUB uses the user ID and password to validate the conversation request.
3. As a result of the conversation request from LUA, LUB requests a related conversation with LUC. Because LUB has already verified the user ID, the FMH-5 sent to LUC contains the user ID and the already-verified indicator.
