Hi Michael,

Firstly, thank you to the team for a great product.

I loaded this staging/1.6.0 build up on one of our servers to test it out.

For building the server, the instructions assume more knowledge than I and 
probably many others have. Perhaps it is an oversight in preparing the Staging 
branch?

The README says load prerequisites then run ./configure

However, there is no ./configure !

I did a web search and found these instructions - Can you please confirm if 
they are correct for Guacamole, or if they need changing.

libtoolize --force
aclocal
autoheader
automake --force-missing --add-missing
autoconf
./configure

Perhaps the correct set of steps can be added to the Staging README file.  Or, 
the appropriate steps can be taken to produce the ./configure file and the 
resultant files added to the Staging branch.

Note: This has never been an issue with server release downloads as they have 
always had a ./configure already present in the directory

As regards testing.

Thus far, I have been testing using the 1.5.5 extensions - auth-totp, 
auth-ldap, auth-json and auth-jdbc-mysql

All looks good so far. I have tested both RDP to Windows 2016 servers and VNC 
to linux servers. Our setup uses AD and TOTP (Google Authenticator) for sign-on 
to Guacamole. Guacamole connections have a mix of pre-configured authentication 
and prompting for credentials. I will continue to use this version and will 
report back if I encounter any issues.

One note - On an RDP connection that had only the DOMAIN pre-configured and NLA 
security set, and prompted for the userid/password - when I swapped in the 
Guacamole 1.6 WAR file, this connection would not work. It would attempt to 
connect and then would just hang on a blank screen. It never prompted for the 
userid/password. There were no errors in the guacd log entries in the 
/var/log/messages file. Doing a hard refresh in the browser (Ctrl-F5) and 
re-logging into Guacamole resolved this issue. I recall reading user messages 
from someone who was seeing similar RDP anomolies recently after upgrading to 
1.5.5 - if you still have access to the thread perhaps suggest the user tries a 
browser hard refresh.

Regards
Vincent

Subject: Please join us in testing "staging/1.6.0"

Hello fellow Guacamole enthusiasts,

We recently merged a massive rewrite of the way guacamole-server handles
rendering that *should* improve responsiveness, framerate, and bandwidth
usage in several cases. The change specifically affects the VNC and RDP
protocol support.

If anyone is interested in testing, please do. The branch containing
these changes is "staging/1.6.0":

https://github.com/apache/guacamole-server/tree/staging/1.6.0

These changes do not depend on anything in guacamole-client, but please
by all means test the "staging/1.6.0" branch of that, too, if you feel
up to the task.

Beware that part of these changes adds support for the RDP "Graphics
Pipeline Extension" (GUACAMOLE-377). This is generally a good thing, but
testing has shown that XRDP's implementation of this uses lossy
compression more often than the Windows RDP implementation, resulting in
the new scroll detection not recognizing things as well as otherwise. If
using XRDP, I would recommend using the "staging/1.6.0" version of
guacamole-client, as well, and selecting the "Disable Graphics Pipeline
Extension" option in the connection settings. It's otherwise enabled by
default.

- Mike
