This issue is still under investigation and we have not determined why it does not work. You can still build Guacamole against FreeRDP3, either natively or by changing the FreeRDP version in the Dockerfile for containers, but Remote App support will be broken. * Kerberos support in Guacamole with FreeRDP3 was never in scope for the 1.6.0 release. It may work in certain situations - my own experience in doing some work to enable it is that, as long as FreeRDP is built with Kerberos support, it should "just work" out of the box without any additional configuration, but there are some additional options that we're looking to add to Guacamole to force certain authentication mechanisms (NTLM or Kerberos), and having Kerberos support was never part of the 1.6.0 scope. -Nick >
