Sentry: Sentry mail without username and password (reset mail settings)

[keros]

Important Details

How are you running Sentry?

Ubuntu 18.04
Installed from pip
Started with systemd

Description

1.) Set mail configuration via gui (smtp, mailserver, username, password, ...).
2.) We need to change to a local Mailserver without authentication (exim4)
3.) Set in /etc/sentry/config.yml the following:

mail.backend: 'smtp'  # Use dummy if you want to disable email entirely
mail.host: 'localhost'
mail.port: 25
mail.username: ''
mail.password: ''
mail.use-tls: false
system.admin-email: '[email protected]'

4.) Sent test E-mail -> SMTP AUTH extension not supported by server

The Problem ist that I can not overwrite the username and the passwort that was set previous in the gui with nothing.
If I go to Admin -> Mail I see the old values in username and password, but there should be not set.

I tried to find the "old" values in the database, but can't find anything there.
I also greped in the "/www" folder for this values and find nothing.
Where are this values stored?
How can I reset them to "nothing"?

I think this was an issue with the initial setup wizard in Sentry 9.1.1 which is fixed in 9.1.2 released yesterday. Are you able to try with that?

Thanks for the help

Just updated to 9.1.2 with the same result.
The Webinterface shows me still the old values for username and password.
If I try a test mail the same error comes up (SMTP AUTH extension not supported by server)

Oh wait, my bad for misunderstanding the issue. As far as I know, when you enter a value from the UI, they are persisted in the DB. I'm guessing the UI doesn't allow empty values?

[keros]

Hmm I made a DB dump and searched for the values so I can delete them, but I could not find anything.
Does the system maybe store this data not in plaintext?

I have a second sentry installation where I never added username/password for the mailserver config in the web ui. On this system (9.1.1) everything runs fine with the local exim4 noauth config.
So empty values should be ok, but If you fill them one times I can not find out how to get them empty again.

me too. 😢

I'll try to get to this but if anyone wants to give it a try, it should not be too complicated and I'm happy to assist them in the process.

@keros - although this is fixed on master now, I'm not sure if we're gonna do a 9.1.3 release with this patch in soon. :(

@BYK Thanks for the patch.
I solved the problem with an workaround. So I don't need a fast solution for it.
But its nice that we can overwrite the GUI data now with the config file, even with nothing.
