Hi Nick, Just to clarify in case my message wasn't clear - you do configure an rdp username and password on the system, and then you add that to guac username/password fields instead of $GUAC_USERNAME/$GUAC_PASSWORD... so when you select the host In guac, it does have to pass the username and password in, but now you're just starting at GDM on the host. So they are using the RDP auth mechanism - just not the way that I'm used to it being used. I wonder if anyone has managed to work around that, or whether that's possible. It's a pity that RHEL10 did away with optional Xorg support.

Just a couple of quick thoughts: * Regarding credential pass-through, this might be something to ask on the Gnome mailing list or forum, or perhaps ask Red Hat if you have a support agreement with them, as I would expect this impacts RDP clients other than Guacamole - that is, you probably can't run xfreerdp or Microsoft Remote Desktop Client and access a RHEL10 system running multi-user mode and expect credential pass-through to work from those clients, either. * Regarding the issue with Guacamole 1.5.5 not working with Gnome RDP - my understanding is that Gnome RDP actually requires the GFX Pipeline (formerly RemoteFX) to function properly, and that was only implemented in Guacamole 1.6.0 as part of the reworking of the rendering engine. -Nick --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
