Mail-Server response: A000002 NO Authentication failed

[Herbert Schwarzer]

Dear Debian-community,

irregularly an x-window pops up with message:

The server (my e-mail-server at my standard internet-provider) rejected the user-name and the password. Login failed. Server response is: A000002 NO  Authentication failed.

BUT nevertheless  my mail-client (Kmail)  d o e s  receive every message.

Serveral attempts by myside to locate the error - believed that problems in Debian 11 with kontact/kmail/akonadi/ could be the reason.

Anyway distribution-tests in my VM (Debian testing / Debian oldstable / Manjaro) lead to the same message.

So can I find the reason within my Debian 11 bullseye   o r   is this is a special behaviour within the mailserver at my provider ( A1.net in Austria)

This only appears within Linux - my (dual-boot) Windows 10  or my smartphone-app runs without such message !

Any help / tips appreciated.

Greetings Herbert

Additional comment:
Now I have installed MATE-Desktop in Debian 11 a n d configured <thunderbird>
as mail-client alternative solution -> no such message.
(all messages are fetched from my mail-server / as with Kmail too :) ).

Further comment of mine (analysis) to narrow down the problem:
1. All emails are fetched from my mailserver (at my service-provider aon.at)
2. Difference of IMAP-Server settings:
within Kmail it is: securemail.a1.net
within Thunderbird it is: smail.a1.net
o.k.--> Thunderbird does NOT produce the error "Mail-Server response:
A000002 NO Authentication failed
3. So therefore I changed Kmail IMAP-Server to: smail.a1.net
Result: Until NOW the error message does NOT appear
Oh wait - just when typing this mail I get the error-message TOO although
'smail.a1.net' is active

Interesting: Official documentation of my service-provider for implementing
email-account does NOT indicate 'smail.a1.net" (!!)

Now I try as imap-server: imap.a1.net with port: 143 (out of official doc of
A1.net-Provider

Hey,

you may want first get the log of the whole IMAP communication, than you
better see in what part it gives you the error:

Dear hefee,

Thank you for your answer. O.k. you gave me an interesting 'homework' (I
learned a lot
meanwhile, because i am just an ONU (Otto normal user)
My logfiles are here:
https://paste.debian.net/1233928/

I hope I have done all the right way - I studied the logfiles but cannot
really see any error -
although I think not to understand everythin in de log.

My ISP is: A1.net
IMAP-Server: securemail.a1.net
SSL/TLS : 993
Authentification: LOGIN (looked up from Kmail)


Are you able to assist ?

Thanks a lot
Greetings from Austria

The logfile seems fine - I can also see no error. So it is not an problem of
an not standard conform IMAP server.

Just a random thought, do you have any other account configured, that failed
to login? You can use akonadiconsole to check this. See the Agent tab ( first
tab), And you can use the "logging" tab (fourth tab) to see what it logs.
Disable logging before closing, otherwise it will forward everything to
.xsession-errors.
If you like to use the console you can do the same with:
QT_LOGGING_RULES="*=true;qt.*=false" akonadictl restart
In our case this should be enough.

Dear hefee,

I thank you very much for being patient.
> logging is done under the logging tab. (the next tab).
YES, I have wachted the LOG of akonadiconsole
but too cannot find any characteristic message in there.
So today a installed in an VM <suduction>-Linux and ONLY set up
the only one mail-account --> same result.
As in former message told, I installed too the MATE-Destop;
logged in an only started thunderbird -> so in this case NO error raised up !

So we end up here - there must be a special condition in akonadi/mail which
causes the mail-server at my ISP (here in Austria = A1.net) to respond with
this message, but however with no effect on delievering emails to my client.

Perhaps I have a chance/way to contact support-engineers to face them with
this message "A000002 NO authentication failed".

Again, THANK you.
Herbert

Hello hefee,

Yes, 'siduction' produces the same pop up window, same behaviour as in my
main Debian 11.2 installation.
So I changed VM-installation siduction -> KDE Neon unstable. Sadly, but the
the same error TOO.
It leaves me somewhat perplexed.
It is a pity - as a normal end-user - but very interested in Debian since
serveral years - I would like to know & explore such behaviour (in our mails I
have learned serveral things :) )

greetings Herbert

One direction you might want to follow is to look for the specific
process which pops up the message -- see
https://kb.froglogic.com/misc/find-process-for-window/

HTH,

Hey,

well the versions in Debian 11.2 are he same than in siduction.

So I changed VM-installation siduction -> KDE Neon unstable. Sadly, but the
the same error TOO.

okay that means that the error is not solved within 21.12.3. So you can search
for upstream bug reports on https://bugs.kde.org, if you find anything
matching your error. That does not not fix your bug, but may be show, if other
email provider are also affected.

I may give a last update of my problem:
It seems to be solved by itself :) maybe an easter-wonder.
After examining several settings in <kmail>-account without any result to the
given error-message "mail-server response: A000002 NO Authentication failed",
since 3 days no message comes up.
Additional examined by installing in a VM a) Debian buster b) Debian Testing
-> effect: no error !
Fine ! But really don't know why.
The only drawback in my standard-system (Debian 11 Bullseye):
Adding google-calendar via google-groupware DOES NOT operate.
Interestingly it works in Debian Oldstable (buster) and Debian Testing
(bookworm).
Hope that eventually there will be an update in Debian bullseye (regularly or
via backports)
