Auth Password Cannot Be Read From a File

I am facing this problem which leaves the error message

1	'Auth' password cannot be read from a file

Because I have set configuration like this in the .opvn file.

1	auth-user-pass user_password.config

And after I googled I found one solution. It says You should recomiple the openVPN. Then I did as it said. It works.
Now Go into the openvpn folder. and follow the below.

1 2 3

./configure --enable-password-save make sudo make install
