       fallback if not given in the session profile.
     - x2gobroker/brokers/inifile_broker.py: Also check for presence of 'host'

     - docs/source: Initialize Sphinx API documentation's .rst files.
     - bin/x2gobroker: If binding the http server fails, a non-zero exit code
       should be returned. (Fixes: #1013).
     - x2gobroker/loadchecker.py: Don't re-read the x2gobroker.conf during
       each cycle of the load checking loop. Rather read it on service startup
       and require a service restart when x2gobroker.conf has been changed.
     - x2gobroker/loadchecker.py: Avoid rare cases where at the end of a load
       checking cycle a negative sleep time would have been calculated.
       (Fixes: #1315). Thanks to Walid Moghrabi for catching this.
     - HTTP broker: Add &login=<server_user> support to plain and json broker
       frontends.
     - SSH broker: Add --login option. This now supports X2Go Broker user and
       X2Go Server username being different accounts.
     - bin/x2gobroker: Correctly use split_host_address() function call.
     - bin/x2gobroker: Don't override already defined logger objects, define
       them properly where needed.
     - Convert one more unicode object into (Python3) string.
     - x2gobroker/tests/test_broker_agent.py: Assure that tests are run without
       loadchecker usage.
     - broker-use-load-checker profile option: Also tolerate 'TRUE' and 'True'.
     - x2gobroker/agent.py: Fix failing execution of LOCAL broker agent. As
       the LOCAL broker agent is executed setuid root, we cannot
       Popen.terminate() (which is unneeded anyway) the process after its
       execution.
     - Ignore SSH broker events for now. Not sure if we will ever support that.
     - Finalize API documentation.
     - Fix regression flaw in x2gobroker/web/json.py, introduced by commit
       9fa371e9.

     - Remove obsolete EPEL 5 support.
     - Switch to HTTPS-based links.

     - Fix %{__global_ldflags} usage if variable does not exist.
     - Commands don't seem to work when wrapped in curly braces (at least on

package: x2gobroker
priority: normal
tags: patch

When using ACLs with the session broker, I wanted to give access to a session setting to ALL users EXCEPT some (namely "formation{1..9}").
I tried this but it didn't work :

=================================================
[TRAVAUX]
fullscreen=true
clipboard=none
name=TRAVAUX
host=tce-server (10.10.10.1)
acl-users-allow=ALL
acl-users-deny=formation1, formation2, formation3, formation4, formation5, formation6, formation7, formation8, formation9
acl-any-order=deny-allow
=================================================

I played with many settings, changing order, using only the "acl-users-deny" option, ... none of them worked as expected.

I ended in thinking that there was a bug with acl-users-allow=ALL which was taking over any other setting.

I did a little fix that seem to work, at least for this use case.

Regards,
Walid Moghrabi
