Default ntopng user is "admin" with password "admin".


It is possible to provide ntopng a list of users credentials in a text file 
with the format:

user.utente.password=5f4dcc3b5aa765d61d8327deb882cf99
user.utente.full_name=Nuovo Utente
user.utente.group=administrator

The md5 sum of the password has to be provided.
In the same way it is possible to overwrite the default "admin" password.


Users can be added/deleted also from the web gui. Changes are written back 
to the users file, if any.


It is also possible to add an user via Redis using the command:

  redis-cli SET user.<username>.password <password md5>

Example of adding a user "utente" with password "password":

  $ echo -n "password" | md5 
  5f4dcc3b5aa765d61d8327deb882cf99

  $ redis-cli SET user.utente.password 5f4dcc3b5aa765d61d8327deb882cf99 

It is possible to list all users via Redis using:

  $ redis-cli KEYS user*
  1) "user.admin.password"
  2) "user.utente.password"
