At work today, I was asked to add some form of authentication to one of our Web Apps. The app itself had no authentication built in and allowed users to submit URLs and files for analysis.

Luckily, I already knew you could use Nginx as a reverse proxy, adding authentication to almost anything.

Getting Nginx to work as a reverse proxy is well-documented, and adding basic authentication is just a matter of writing passwords to a file, then editing your config. There had to be something better. I set about searching for an authentication front-end, with the ability for provisioning of new users.

It provides a pretty front end for managing and creating authentication accounts, whilst also providing a backend to allow nginx to ensure the current user is authenticated. Downloading and configuring the service is pretty straight-forward. My 2FA config file was simple, I just had to follow the readme on github.

The Nginx configuration needed a little more coaxing into life. I finally got it working with the following config:. The majority of the config here is to handle what the reverse proxy serves itself, and what it passes to our webapp. This code handles how logging occurs.

I wanted to log specific requests to the proxy, so I used these two paragraphs. Requests with the 1; ending are considered candidates for logging, with the default being set as do not log. If the 0 and 1 were reversed, this would be a blacklisting operation instead.

The second section handles what format I want the log to use. This allows me to see which user made the request. This section also tells nginx what to do if the user has not been authenticated yet. In this case, instead of throwing a error, the user is redirected to the 2FA login page, with the orginally requested page included in the URI. I basically let nginx know that any of these files are to be executed by php7. Nothing really special here.

The top secion of code ensures that static content is served from the Proxy, and not passed to the main webapp. Next, we state that that we want a new log file to be created, using the previously set phpcookie format and validated against our previously set loggable whitelist.

I then set the reverse proxy destination to be our local port, and require authentication for this access. Proxy buffering is diabled, as my WebApp uses streamed data and buffering can introduce breaking delays in this stream. But what if you needed something more robust?Preparation and installartion nginx 2. Installation of Jitsi3.

TOTP is an algorithm-generated temporary passcode that is used for strong authentication.

You need to deploy and configure travelocity. See deploy the sample application for more information on configuring travelocity application. In the previous section of this guide you have deployed and registered the travelocity. Let's edit the same service provider to configure totp as an additional authentication factor. Locate the "travelocity. Click Add Authenticator that is under Local Authenticators of Step 1 to add the basic authentication as the first step.

Adding basic authentication as a first step ensures that the first step of authentication will be done using the user's credentials that are configured with the WSO2 Identity Server. Click Add Authenticator that is under Local Authenticators of Step 2 to add the totp from the drop down as the second step. You can use the Google Authenticator Application to generate the one-time passwords tokens. Click on Security and go to Multi-factor authentication.

Enter the verification code from your Google Authenticator Mobile Application to authenticate. Alternatively, you can generate the verification code by clicking on Get a Verification Code and use the code that is sent to your email address. See send email with totp for more details on how to configure email sending.

If your verification is successful, you are taken to the home page of the travelocity. You can disable the TOTP authenticator by adding the following configuration to the deployment. You may configure any of the following parameters to change the behaviour of the TOTP authenticator according to your requirements.

The following table describes the definition of the parameters and the various values you can configure for the authenticator. An admin can activate the feature to enable the TOTP authenticator in the authentication flow by changing the enrolUserInAuthenticationFlow values true or false.

If you use the secondary user store, enter all the user store values for the particular tenant as comma separated values.

While doing the authentication, first server checks whether there is an XML file uploaded to the registry. If that is so, server reads it from the registry but does not take the local file. If there is no file in the registry, then it only takes the property values from the local file.

This is how the user store configuration is maintained per tenant. You can use the registry or local file to get the property values. The following is the Admin Service used to obtain the QR code. Additionally, users may receive an email consisting the TOTP code during the authentication flow. You can edit and customize the email template. For more information on how to do this, see Customizing Automated Emails.

Tip Alternatively, you can generate the verification code by clicking on Get a Verification Code and use the code that is sent to your email address. Sample configurations of the authenticator with default Values [authentication. To enable scanning QR code during authentication flow An admin can activate the feature to enable the TOTP authenticator in the authentication flow by changing the enrolUserInAuthenticationFlow values true or false.

If you don't enable it at this stage, the TOTP error page appears. Sign in to the Management Console as a tenant administrator.

I use nginx in front of a variety of web services to handle SSL termination using letsencrypt, which is amazing and you should also use. If the endpoint returnsthe parent request is allowed to succeed, otherwise a error is returned.

You can set up nginx to then redirect the user to a login page where they can do whatever they need to assert proof of identity. In this case, the auth endpoint is reverse proxied to the simple script in this repo, which does things like token checking and presenting a login form. Skip to content.

ChristophWurst closed January 27,pm Enabling TOTP will require using a tool usually an app to generate a one time use numeric code that is required in addition to the username and password to successfully login. With TOTP installed and configured on the server, it is currently enabled on a per user basis in Guacamole.

Any user with the permission "change own password" will be presented with the TOTP enrollment screen on first login. Once enrolled they will be presented the TOTP code entry screen after logging in with their primary credentials. This permission is not set by default for users in Guacmaole and needs to be set manually one-by-one or via scripting which is beyond the scope of this document or my install script.

There is currently an issue filed and a pull request to allow users to be automatically added to the JDBC module upon successful login from another module which could resolve the matter but is unlikely to be included in recent future releases of Guacamole unlikely to be in 1.

The script will prompt for a few pieces of information to configure TOTP on the server side. In most cases the default values are what should be used. Numbers depend on what TOTP app is being used and what it supports. Most only support 6 digits, 30 seconds and SHA1. If you use an app that supports other configurations you can match the setting applied using this Guacamole install script to the settings supported by your TOTP app.

I do not endorse any and only provide this list for reference. I highly recommend researching the matter and picking the best option for your needs. Many password managers also support generating TOTP codes, but implementing this is beyond the scope of this page and I will not cover using a password manager for this purpose. Skip to content. The TOTP parameters must be correctly set. A user must have, in Guacamole, permissions to change their own password. If not specified, "Apache Guacamole" will be used by default.

Legal values are 6, 7, or 8. By default, 6-digit codes are generated. Period in seconds a code is valid The duration that each generated code should remain valid, in seconds. By default, each code remains valid for 30 seconds.
