This is more for the programming geeks out there than anyone else. If you are looking for a quick and dirty way to store your BlackBerry username and password when using the BESUserAdminClient.exe, refer to the following document.
It allows you to simply pass a secondary password that will reference the credentials stored in the registry.
To set the password:
BESUserAdminClient -set_client_auth "-username ADU1 -password ADP1 -ad_auth -domain D1" -set_p password1
To access the credentials from the registry:
BESUserAdminClient -p password1
