We would evaluate guacamole for enterpriese usage, but SSO would be a really relevant feature here. Saphirim As you can see, this is still in the works - it needs to be reviewed and probably has some work to do on it before it's ready.

Should be pretty close, but we've also got some high-priority items we're trying to work for the next release, so not certain it will make it. If you need a test infrastructure you can contact me and I will share some accounts and an IdP and SP setup. It does not support SLO, yet, but should work with version 1.

And have the extension generate the correct metadata file for guacamole saml, to be used in the idp. LeBrad tuxcrafter It's been a little while since I did any testing on this, but this is what I have in my guacamole. Anyway, test away, feel free to let me know if you run into any issues with it. I do need to rebase it against the latest master repo and redo some of the testing and make sure it's still good, but not sure when I'll get to that.

This comment has been minimized. Hello, out of interest: what are the latest plans to integrate SAML into a official release of guacamole?

I probably need to configure the following settings somewhere: idp-entityId metadata idp-singleLogoutService. Then it would be good to have a mapping options for the username and groups. Thanks for the properties. Where do we place the certificate for the IdP?Comments, attachments, related issues, and history from prior to acceptance have not been copied and can be found instead at the original issue.

It would be nice if Guacamole had OAuth2 authentication plugin. OAuth2 is wide spread in web technologies and Guacamole deserves to have its implementation of the protocol. My company had this use case and for now we are using a custom authentication plugin because implementing a generic OAuth2 compatible Guacamole authentication plugin presents some difficulties.

OAuth2 requires clients Guacamole in our case to register a redirect URI so that the OAuth2 server could callback the application when the user has been identify or rejected on its side. It also passes along some informations like tokens or reason of failure as part of the URL. In the case of Guacamole, the Angular frontend uses those local URI data to determine which page to display. Angular behavior cannot be easilly turned off and would lead to heaver code changes and uncompatibility with older browser.

Connection list is retrieved at user login. It doesn't make sense to expect the OAuth server to give such list as it would not be generic enough. Fortunatly, connection lists get merged between authentication plugins and this OAuth plugin could be paired with another one which goal would just be to provide the connection list. First, this token needs to be invalidated by Guacamole when user explicitly disconnects. Second, there is no way for Guacamole to know if a stored auth token is still valid.

Leaving the user to freely keep on using its Guacamole session even thought the token has expired. I am just leaving these though here so the Guacamole community could start an discussion on this matter. Log In. Type: New Feature. Status: Resolved. Priority: Major.

Resolution: Done.I'm a sysadmin at a medium-sized users worldwide non-profit. My colleagues and I are currently investigating whether guacamole would be a good solution for a portal. What we want to do is something like the following. Provide an Internet facing portal page, where after users authenticate with password and sms or yubikey, they will get access to guacamole connections. Now the main issue we see at the moment is how to achieve credentials passthrough.

So a form of SSO basically. Is it already possible to pass credentials to guacamole and then let guacamole pass those down to the rdp server s? If it isn't possible already and custom code is required, I made be able to persuade my management to spend some money on such modifications. I suppose the proper route for that is through gyptodon, correct? What you describe is possible.

You wouldn't need to modify Guacamole, but you would need to write an extension to integrate your SSO system within Guacamole's authentication and configuration model.

This project can now be found here.But, what if you want to serve up your own applications from the enterprise LAN or access your home desktop over the Internet? However, this approach typically involves installing the corresponding software client on the machine from which users want to access the remote application.

If you do not trust the built-in encryption, or if none exists, you will soon see the need for a VPN client to provide encryption and authentication.

This is all very unfortunate, for example, if you are working on a computer in the hotel lobby or an Internet cafe and cannot install your own applications. However, these solutions typically impose specific requirements on the browser and plugins. Often you need Java, Flash, or ActiveX — and maybe even a specific version.

The alternative is Guacamolean HTML5 web application that supports graphical access via remote desktop protocols RDPs directly in the browser, without the need for additional plugins. The program is licensed under the AGPLv3 and, in the current version 0. For example, you cannot transmit audio data or connect network drives over RDP. The desktops accessible via RDP or VNC can run either on the application server itself or on a different computer on the network.

Guacamole promises near-native performance and offers international keyboard support and an on-screen keyboard, where you can use the mouse to simulate keyboard input. These are ideal conditions for rendering a desktop and applications in the browser. The prerequisite then is just a browser that supports the Canvas element. Fortunately, the Guacamole website has prebuilt packages for several distributions.

The Downloads section of the website provides packages for Debian 6. Alternatively, you can build Guacamole from the source code. For a test, you will need Guacamole 0. Next, download the prebuilt packages for Ubuntu Go to the new directory. The Tomcat server now requires symbolic links: one to each of the files guacamole. Additionally, you need to add the tomcat6 user to the new guacamole-web group, which you can do automatically by installing the package:.

Alternatively, the manual procedure is described on the Guacamole project website. Finally, reboot the Tomcat server and select yes at the prompt Figure 2or enter. For access via Guacamole to the desktop to succeed, of course, you also need to share a desktop.

This will work just as well with a real Windows terminal server or a computer on which the desktop is shared via a VNC server. Next, you need to introduce Guacamole to the credentials of the remote desktop so that access via the browser will work.

In the example, I will set up a connection for user tom with a password of test on a Windows system with an IP address of Next, store the password for the VNC server in the following section:. Make sure the machine you entered in user-mapping. After successful authentication with the specified username and password, you should be able to log in to the desktop on the target system, as displayed in your browser Figure 4.

You can then log in with your Windows credentials. The default Guacamole setup works, but it is anything but secure because access to the login page is unencrypted. Thus, you are urgently advised to install Tomcat with SSL support. For a how-to, check out the detailed Tomcat documentation online.

Another unfortunate feature is that the password for opening the connection to the RDP server and — if you use a VNC connection also the VNC password — are stored in the clear in the user-mapping.

Thus, you will want to change the owner and permissions for the user-mapping. Alternatively, Guacamole also offers the possibility of creating hashed passwords only in the config file. Listing 2 shows the corresponding section of user-mapping. You can quickly view the password hash at the command line with the md5sum utility:.

Next, add this hash value instead of the password to the configuration.We compiled guacamole succesfully on freebsd, but cannot connect to our rdp farm behind a broker. We can login, but if we get a redirect from the farm to a different server, the screen stays blank.

Is there some way to get this to work? I understand that it works in Freerdp, and that guacd is using the Freerdp code base right? Edwin, it's always frustrating when a post in a forum goes neglected or unnoticed, let alone for a few months, so I can definitely sympathize I'm not sure if you intended to sound this way, but being hostile will not attract the help you desire.

If no one from the greater community responds, I tend to jump in, but this cannot always happen. Not exactly.

Add support for SSO via OpenID Connect

The RDP client which is built as part of guacamole-server, libguac-client-rdp, does link against their library libfreerdpyes.

That library is the core of their RDP client implementation, so it is likely the functionality for connecting through an RDS broker is there and that Guacamole should be able to leverage it, but since this is apparently not working, we need to determine the difference in how libfreerdp is being used within Guacamole vs. Most likely, but it depends on how exactly this is already achieved in FreeRDP. When you connect using the FreeRDP client "xfreerdp"do you have to specify any additional options at the command line?

What RDS broker are you referring to? Are there any steps you can provide that would allow us to reproduce this on our end? Help Create Join Login. Operations Management. IT Management. Project Management.

Come on guys Does nobody have a setup like this? Last try Michael Jumper - Oh no!CAS is an open-source Single Sign On SSO provider that allows multiple applications and services to authenticate against it and brokers those authentication requests to a back-end authentication provider.

This module allows Guacamole to redirect to CAS for authentication and user services. This module must be layered on top of other authentication extensions that provide connection information, as it only provides user authentication. The CAS authentication extension is available separately from the main guacamole. The link for this and all other officially-supported and compatible extensions for a particular version of Guacamole are provided on the release notes for that version.

The CAS authentication extension is packaged as a. Guacamole extensions are self-contained. Copy guacamole-auth-cas The CAS authentication extension provides two configuration properties, both of which are required.

This should be the full path to the base of the CAS installation. The URI to redirect back to upon successful authentication. Normally this will be the full URL of your Guacamole installation. See the section on ClearPass below. Guacamole will only reread guacamole. Doing this will disconnect all active users, so be sure that it is safe to do so prior to attempting installation. When ready, restart your servlet container and give the new authentication a try.

CAS has a function called ClearPass that can be used to cache the password used for SSO authentication and make that available to services at a later time. Once you have CAS configured for credential caching, you need to configure the service with a keypair for passing the credential securely. The public key gets installed on the CAS server, while the private key gets configured with the cas-clearpass-key property.

If TokenFilter is not working as expected because this value isn't populated, and the fact that it isn't populated is a bug, then that's a legitimate reason to make this change, and there's no need to call out the specific things that break because it's absent. If it's necessary, it's necessary. If this truly is a hack, however, it might be worth instead looking into ways that TokenFilter could be modified to not depend in the username in the Credentials object.

Going the AuthenticatedUser route looks like it would require one of the following approaches:. It seems to me that setting it up inside the authentication module is the right way to go - it results in the fewest places that have to be reworked, and makes it available across the various places where those Credentials objects are used.
