[Ovmsdev] Server Authentication Confusion

You will require an authentication plugin for the server to authenticate connections with (and select the plugin you want in ovms_server.conf). Two are provided as examples:

AuthDrupal.pm (Authenticates against the Drupal user database, with Drupal’s multiple-iteration hashes)
AuthNone.pm (a stub to base your own off)

The simplest approach would be to copy AuthNone to AuthBasic (or some such name) and implement the Authenticate() function to return the user permission (or empty string if authentication fails).

Alternatively, you could use AuthDrupal and manually populate the users / ovms_owners table - but you would need to encode the passwords appropriately.

Regards, Mark.
