Wherever a password argument
is required (such as -w bind-password or -q configuration_password), you can
use the “ -” argument to tell the password
program to read the password from STDIN.
If you use the “-” value for multiple
password options, idsync will prompt you for passwords
based on the arguments’ order.
In this case, the program would expect the bind-password first,
and then for the configuration-password.
