- `password`: if omitted, then no password is required. Otherwise, this
|
|
||||||
can either be a string, specifying a plain text password, or
|
|
||||||
a dictionary generated by the `galene-password-generator` utility.
|
|
||||||
|
|
||||||
For example,
|
Galene implements two authorisation methods: a simple username/password
|
||||||
|
authorisation scheme that is built into the Galene server, and
|
||||||
|
a token-based mechanism that relies on an external server. The simple
|
||||||
|
mechanism is intended to be used in standalone installations, while the
|
||||||
|
server-based mechanism is designed to allow easy integration with an
|
||||||
|
existing authorisation infrastructure (such as LDAP, OAuth2, or even Unix
|
||||||
|
passwords).
|
||||||
|
|
||||||
|
### Password authorisation
|
||||||
|
|
||||||
|
When password authorisation is used, authorised usernames and password are
|
||||||
|
defined directly in the group configuration file, in the `op`, `presenter`
|
||||||
|
and `other` arrays. Each member of the array is a dictionary, that may
|
||||||
|
contain the fields `username` and `password`:
|
||||||
|
|
||||||
|
- if `username` is present, then the entry only matches clients that
|
||||||
|
specify this exact username; otherwise, any username matches;
|
||||||
|
- if `password` is present, then the entry only matches clients that
|
||||||
|
specify this exact password; otherwise, any password matches.
|
||||||
|
|
||||||
|
For example, the entry
|
||||||
|
|
||||||
{"username": "jch", "password": "1234"}
|
{"username": "jch", "password": "1234"}
|
||||||
|
|
||||||
specifies user *jch* with password *1234*, while
|
specifies username *jch* with password *1234*, while
|
||||||
|
|
||||||
{"password": "1234"}
|
{"password": "1234"}
|
||||||
|
|
||||||
specifies that any (non-empty) username will do, and
|
allows any username with password *1234*, and
|
||||||
|
|
||||||
{}
|
{}
|
||||||
|
|
||||||
allows any (non-empty) username with any password.
|
allows any username with any password.
|
||||||
|
|
||||||
|
By default, empty usernames are forbidden; set the `allow-anonymous`
|
||||||
|
option to allow empty usernames. By default, recording is forbidden;
|
||||||
|
specify the `allow-recording` option to allow operators to record.

### Authorisation servers
|
||||||
|
|
||||||
|
Galene is able to delegate authorisation decisions to an external
|
||||||
|
authorisation server. This makes it possible to integrate Galene with an
|
||||||
|
existing authentication and authorisation infrastructure, such as LDAP,
|
||||||
|
OAuth2 or even Unix passwords.
|
||||||
|
|
||||||
|
When an authorisation server is used, the group configuration file
|
||||||
|
specifies the URL of the authorisation server and one or more public keys
|
||||||
|
in JWK format:
|
||||||
|
|
||||||
|
{
|
||||||
|
"authServer": "https://auth.example.org",
|
||||||
|
"authKeys": [{
|
||||||
|
"kty": "oct",
|
||||||
|
"alg": "HS256",
|
||||||
|
"k": "MYz3IfCq4Yq-UmPdNqWEOdPl4C_m9imHHs9uveDUJGQ",
|
||||||
|
"kid": "20211030"
|
||||||
|
}, {
|
||||||
|
"kty": "EC",
|
||||||
|
"alg": "ES256",
|
||||||
|
"crv": "P-256",
|
||||||
|
"x": "dElK9qBNyCpRXdvJsn4GdjrFzScSzpkz_I0JhKbYC88",
|
||||||
|
"y": "pBhVb37haKvwEoleoW3qxnT4y5bK35_RTP7_RmFKR6Q",
|
||||||
|
"kid": "20211101"
|
||||||
|
}]
|
||||||
|
}
|
||||||
|
|
||||||
|
The `kid` field serves to distinguish among multiple keys, and must match
|
||||||
|
the value provided by the authorisation server. If the server doesn't
|
||||||
|
provide a `kid`, the first key with a matching `alg` field will be used.

# Authorisation protocol
|
||||||
|
|
||||||
|
If a group's status dictionary has a non-empty `authServer` field, then
|
||||||
|
the group uses token authentication. Before joining, the client sends
|
||||||
|
a POST request to the authorisation server URL containing in its body
|
||||||
|
a JSON dictionary of the following form:
|
||||||
|
```javascript
|
||||||
|
{
|
||||||
|
"location": "https://galene.example.org/group/groupname",
|
||||||
|
"username": username,
|
||||||
|
"password": password
|
||||||
|
}
|
||||||
|
```
|
||||||
|
If the user is not allowed to join the group, then the authorisation
|
||||||
|
server replies with a code of 403 ("not authorised"). If the user is
|
||||||
|
allowed to join, then the authorisation server replies with a signed JWT
|
||||||
|
(a "JWS") the body of which has the following form:
|
||||||
|
```javascript
|
||||||
|
{
|
||||||
|
"sub": username,
|
||||||
|
"aud": "https://galene.example.org/group/groupname",
|
||||||
|
"permissions": ["present": true],
|
||||||
|
"iat": now,
|
||||||
|
"exp": now + 30s,
|
||||||
|
"iss": authorisation server URL
|
||||||
|
}
|
||||||
|
```
|
||||||
|
The `permissions` field contains the permissions granted to the client, in
|
||||||
|
the same format as in the `joined` message. Since the client will only
|
||||||
|
use the token once, at the very beginning of the session, the tokens
|
||||||
|
issued may have a short lifetime (on the order of 30s).
