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.username.password=5f4dcc3b5aa765d61d8327deb882cf99
user.username.full_name=New user
user.username.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 a user via Redis using the command:

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

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

  $ echo -n "password" | md5 
  5f4dcc3b5aa765d61d8327deb882cf99

  $ redis-cli SET ntopng.user.username.password 5f4dcc3b5aa765d61d8327deb882cf99 

It is possible to list all users via Redis using:

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