Users registration

By default, a SAYMON administrator can create new users via graphical interface (see User and Group Management), Keycloak or LDAP.

Also, the administrator can configure SAYMON to let users register by themselves using the User registration window.

server.user.auth_enabled parameter of the server configuration also allows users to delete their own account.

To enable "self-registration" perform the following steps:

In the User subsection of the Server section of the server configuration file /etc/saymon/saymon-server.conf set the variable auth_enabled to true:
```
"server": {
    "user": {
        "auth_enabled" : true
    }
}
```
In the same section configure the Email subsection.
In the client configuration file /etc/saymon/saymon-client.yaml add the parameter authEnabled and set it to true:
```
authEnabled: true
```
Restart SAYMON:
```
$ sudo service saymon-server restart
```

server.user.auth_enabled parameter also enables the ability to remove user’s own account.
