In some situations it is required to start Notes automatically without entering the password. Such situation can be locally running agents on a Notes client. Changing password to empty string is often not a good solution for different reasons.
But there is a solution for this problem. Using extpwd example from Domino C API toolkit it is possible to accomplish this task.
I've compiled the example and you can try it on your Notes client.
Steps to setup the solution:
1) Copy nextpwd.dll to the Notes program directory.
2) Create a file called password.txt in the notes\data directory and type the Notes password there.
3) Add line EXTMGR_ADDINS=extpwd to notes.ini
Now when you start Notes client, it will not ask you for password.
