QuestionEDITED Where and how to change DBus security access to "name "? ( Added Link at the front of the original post.) Pin

Addendum

The following link MAY hold the answer.
I need time to study it.

dbus-daemon[^]




I have posted the following in another (Linux) forum and got no response.
I am hoping I do better here.



The enclosed error tells me to change dbus "configuration" file.
There are few problems with such laconic error.

#1 There are no such things as single "configuration " file.
#2 What I assume is main "session.conf"( NOT configuration - just conf ) has been deleted and replaced by others in THREE different folders.
#3 The instruction in ONE of them - "session.conf" tells specifically NOT to modify this file. That is fine , I generally can follow instruction how to supplement this file BUT

#4 Is this "session.conf" the correct file to supplement ?
#5 Where / HOW EXACTLY do I change this "security " - using "session.conf" as template to be able to name my own dbus ?

PS
I understand the "session.conf" is NOT just plain script / text file so I ma reluctant to "change " anything anyway in it. (Just found out it is in HTML format, I have no experience with HTML!)

Here is the compiler error output:

conn = 0xadff00
register our name on the bus, and check for errors
TESTtest.signal.source
err.message = Connection ":1.77" is not allowed to own the service "TESTtest.signal.source" due to security policies in the configuration file
Failed dbus_bus_request_name: : Resource temporarily unavailable 


Addendum:
I have found two x.conf "system.conf" and "session.conf". Neither one of them is very intuitive to let me change the "naming" security to correct the error.



I am enclosing a copy of full "session.conf" I am supposedly modify / copy / use to change the "naming" security. I hope somebody can point out to me what needs to be changed and how to duplicate / make the "supplemental file" as instructed.

FYI - the only entry mentioning "name " is in "system.conf"

 <!-- <limit name="max_replies_per_connection">128</limit> -->



PS
I have not figured out how to copy the entire "terminal" output , so there may be duplicates.
The file is included to help to identify WHAT needs to be changed.

As always , any help would be greatly appreciated.

Addendum:
Here is what is in the "removed " "session.conf" file.
Which helps a little but bring up another "question"
What is "session.d" folder for - which is empty ?

jim@jim-desktop:/usr/DBUS/share/dbus-1$ ls
services  session.conf  session.d  system.conf  system.d  system-services
jim@jim-desktop:/usr/DBUS/share/dbus-1$ cd session.d
jim@jim-desktop:/usr/DBUS/share/dbus-1/session.d$ ls


I guess I need for have
<busconfig> element containing configuration directives
in my supplemental file.


<!--
This configuration file is no longer required and may be removed.

In older versions of dbus, this file defined the behaviour of the well-known
session bus. That behaviour is now determined by
/usr/DBUS/share/dbus-1/session.conf, which should not be edited.

For local configuration changes, create a file
session-local.conf or files matching session.d/*.conf in the same directory
as this one, with a <busconfig> element containing configuration directives.
These directives can override D-Bus or OS defaults.

For upstream or distribution-wide defaults that can be overridden
by a local sysadmin, create files matching
/usr/DBUS/share/dbus-1/session.d/*.conf instead.
