slaptest when run with -f and -F arguments for slapd.conf to slapd.d conversion
returns all the messages only in stderr instead of returning success messages in
stdout.

I am developing a tool which sends commands over SSH and catches the replies
using the Python Library Paramiko. It clearly captures stdin, stdout and stderr
when a command is run and returns to the user
(http://docs.paramiko.org/en/2.2/api/client.html#paramiko.client.SSHClient.exec_command)

I noticed that the message "config file testing succeeded" is returned back in
the channel stderr and not stdout. 

Kindly take a look. It might be a one line fix. :)

Thanks and Regards,
