Re: Does Guacamole support PKI/Smartcard authentication for RDP (instead of username/password)?
Hi Craig you wrote on the mailinglist that you just use a "65 character PW" now I would like to do the same.. but how can we do this if I want to use AD functionality like groups etc.. while beeing able to login to another System (form inside the corporate network) for example usign the normal password.. Is there somekind of GPO which allows to use one PW for all users instead of the real one just for a few hosts? I would love to hear form you to get this running :) it really would help me very much!

Re: Does Guacamole support PKI/Smartcard authentication for RDP (instead of username/password)?
I would say this is better to solve within a proper IdP rather than an end-node webapp like guacamole. ie set up guacamole to use SAML or OpenID connect to a "proper" Identity provider and make that thing do the high-security checks. eg we use Apache with mod_auth_mellon as a reverse proxy frontend to guacamole (set to use http-auth-header). As we are an "Okta shop", that means we can lean into all the MFA offerings they have - guacamole doesn't have to worry it's pretty little head about it ;-). But Google's OpenID-Connect would do just as good a job. Or this, or that, etc :-) On Sat, Oct 30, 2021 at 6:12 AM Craig Sawyer wrote: > OK I'm all for short-lived auth certs, I'm a fan.

Re: Does Guacamole support PKI/Smartcard authentication for RDP (instead of username/password)?
If it's a very large document, can you convert it to text and put it in the appropriate JIRA case and then post the case link here? If it's short enough, please just send the text directly to the mailing list here. Maybe the list admin(s) have policy about this sort of thing, I dunno, if they do, please follow list policy. The links you sent didn't work for me using curl, so I have no idea what they say. On Tue, Nov 2, 2021 at 3:07 AM Alexandre Veyradier wrote: > > Good afternoon!

Re: Does Guacamole support PKI/Smartcard authentication for RDP (instead of username/password)?
OK I'm all for short-lived auth certs, I'm a fan. But I'm confused as to the use case/utility here. The idea you have is: A: User visits Guacamole and authenticates via some method and guac returns a Guac Auth Cookie to the browser. B: User clicks on host SSHA in Guac UI, and Guac then determines SSHA needs a short lived auth token/cert and then does one of these: 1: Guac impersonates the user, to generate a short lived auth token/cert/OTP for SSHA 2: Guac has the rights to generate such things for ALL users, no impersonation needed C: Guac connects to SSHA, sends the short lived cert to SSHA and then returns a full connection to the user. To alleviate all of this complexity in our infrastructure, for Guac, our virtual desktop systems have a 65 character randomly generated password, shared only with Guac. Since brute force attacks against a 64 char password is currently known to require more energy than the entire known universe, we feel confident the possible leak of an account can only happen from guac being compromised or the target host leaking it somehow. Either way a short lived cert doesn't buy us anything(especially since using the Guac SQL DB, we can update those passwords at will whenever we want with some SQL queries).

The first one is definitely not implemented, yet, and I don't think there's a JIRA feature issue for it, either. For the second one, I'm not entirely sure what you mean. Several SSO platforms are supported in Guacamole - CAS, OpenID, and SAML - and within those some of them have support for validating logins using various means, including certificates between Guacamole and the SSO IdP. I know there was a recent e-mail on the list regarding getting SAML to work with certificate validation, so there may be some issues with that, and it's worth testing out further. In the end, doing certificate-based authentication to Guacamole shouldn't require too much work - the guacamole-ext framework provides relatively simple ways for supporting new authentication mechanisms, and SmartCards are really just x509 certificates, so really anything that supports certificate-based authentication should work. I know CAS supports x509 authentication, so it would probably be reasonably easy to get CAS x509 -> Guacamole authentication working without having to modify any code at all. -Nick

Re: Does Guacamole support PKI/Smartcard authentication for RDP (instead of username/password)?
Thanks for your reply, Nick. On #2: User workstation —> Guacamole intermediate server —> Target RDP or SSH server After the initial authentication to Guacamole with SAML/ smartcard/etc, If the intermediate server could get a ephemeral certificate (on behalf of the authenticated user) from a CA and allow auto login over SSH snd RDP to the target server.

In the end, doing certificate-based authentication to Guacamole shouldn't require too much work - the guacamole-ext framework provides relatively simple ways for supporting new authentication mechanisms, and SmartCards are really just x509 certificates, so really anything that supports certificate-based authentication should work. I know CAS supports x509 authentication, so it would probably be reasonably easy to get CAS x509 -> Guacamole authentication working without having to modify any code at all. -Nick

Love Guacamole so far! For remote Windows servers that support only smartcard authentication, would like the following capabilities: 1. Smartcard redirection 2. Generation of ephemeral certs on the “gateway” for seamless “SSO” Are these features available or on the roadmap? Thanks, -rajeev
