auth.js Node.js-based App Server to authenticate against and OpenLDAP server using the passport-ldapauth package for LDAP authentication.
ldap_data.ldif Information to populate the OpenLDAP database. Contains a single user mobileuser.
The following code snippets highlight the call to the App Server and the Couchbase Lite code to authenticate using the session_id.
Authenticate user with App Server by calling POST /login/
reqBody.put("username", <user supplied username>);
reqBody.put("password", <user supplied password>);
String url = <App Server host>:8080/login;
RequestQueue queue = Volley.newRequestQueue(<context>);
JsonRequest<JSONObject> jsonRequest = new JsonObjectRequest(
Request.Method.POST,
url,
reqBody,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
// get session_id from response
try {
String sessionID = response.getString("session_id");
// Store session_id
} catch (JSONException je) {
// Handle exception
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
// authentication failed
}
});
queue.add(jsonRequest);
Create one-shot replication
Create one-shot replication using saved session_id and re-authenticate if Sync Gateway session has expired.
URI url = null;
try {
url = new URI(mSyncGatewayEndpoint);
} catch (URISyntaxException e) {
e.printStackTrace();
return;
}
ReplicatorConfiguration config = new ReplicatorConfiguration(database, new URLEndpoint(url));
config.setReplicatorType(ReplicatorConfiguration.ReplicatorType.PUSH_AND_PULL);
config.setContinuous(false);
config.setAuthenticator(new SessionAuthenticator(sessionID));
Replicator replicator = new Replicator(config);
replicator.addChangeListener(new ReplicatorChangeListener() {
@Override
public void changed(ReplicatorChange change) {
CouchbaseLiteException error = change.getStatus().getError();
if (error != null) {
if (error.getCode() == 10401) {
// session expired; re-authenticate
}
}
...
}
});
replicator.start();
