Bitwarden - Self-hosted password manager

@murgero It's available to anyone, using the cli tool (https://cloudron.io/blog/2017-03-08-cli-part2.html)

[murgero]

@necrevistonnezr in theory sure, but last I tried (about a month ago) it said my user account was denied access (error 503)

Started digging back into email sending and got closer.

I just noticed that the Cloudron docs say that the STARTLS uses a self signed cert, which makes sense given that the host I'm using is mail and not my.example.com.

So I switched back to unencrypted and enabled more verbose logging. Ended up with:

So this is definitely more descriptive. Seems like the server is rejecting the request.

: 550 Mail from domain 'example.com' is not allowed from your host<CRLF>

Can you check if the email for example.com is not set to Disabled under the outbound relay email settings?

Tried updating the bitwardenrs-app today to its current domain; usually it would just install (and upgrade) the app. Today I got the following error:

➜ cloudron install
ERROR (node:9463) Warning: Setting the NODE_TLS_REJECT_UNAUTHORIZED environment variable to '0' makes TLS connections and HTTPS requests insecure by disabling certificate verification. [ internal/process/warning.js:27:3 ]
Location: bit
ERROR Failed to install app. Domain 'bitwarden.domain.com' is in use [ /Users/user/.nvm/versions/node/v12.7.0/lib/node_modules/cloudron/src/helper.js:68:29 ]

[necrevistonnezr]

Tried with the LTS node version today - still the same error "Domain is in use". Anyone have an idea why?

[girish]

@necrevistonnezr You have to delete the DNS entry manually in the DNS provider. What's hapenned is that the dns already has an entry for the subdomain. Cloudron will never overwrite existing DNS records.

This is getting fixed with https://git.cloudron.io/cloudron/box/issues/644. Cloudron will then overwrite DNS entries with that flag set.

If the above is not the issue, maybe there is another app on that subdomain? (Also, check any redirects you have to set for other apps).

Where am I supposed to delete the DNS entry? Is the "DNS provider" something in the cloudron control panel?

I have no other apps / redirects regarding that subdomain.

@necrevistonnezr - He means delete the DNS entry from your DNS service provider itself for the domain. So if you already have bitwarden.domain.com in your DNS listing for your domain, then remove the bitwarden entry and then re-create with Cloudron.

That was not the issue since I did not have a subdomain entry in my DNS settings (I have a wildcard DNS entry). The issue was that cloudron-cli was not able to connect to my cloudron properly (TLS, https issues) for reasons I don't know (I told support about it).

After using cloudron login --allow-selfsigned I was able to build and update the bitwarden...

[d19dotca]

@necrevistonnezr Ah interesting, good to know you figured that out then. Normally when that error is seen (I came across it quite a lot when setting up new environments on Cloudron as I learned the platform), it was always because I had already defined a "www" subdomain in my DNS provider, for example, so it then needed me to remove it before it could create it automatically by itself.

Ok. So I think I've just figured out the email issue, but don't have a fix yet.

When using the non-smtps connection, the logs show that lettre, the Rust email library that Bitwarden_rs uses, recognizes that the server supports several authentication methods, including Authentication(Plain), which is what swacks uses when successfully sending on the same port. However, lettre refuses to use it because we aren't using an encrypted connection and it doesn't want to send credentials in the clear. (Checked here, defined as empty here).

Unfortunately, using smtps is not a solution either because it appears that lettre is trying to validate the certificate, but that certificate is invalid.

A patch to Bitwarden_rs may be required to tell lettre to allow sending credentials over an insecure connection using this method or by telling it to accept insecure certs.

I'm working on a patch for Bitwarden_rs to allow insecure SSL connections so that it will accept a self signed cert.

[iamthefij]

Also, it looks like MySQL support is available now. Once I get all the email support sorted out, I'll try to roll that in as well.

[iamthefij]

@iamthefij Ok. My bitwarden_rs patch works. I'm going to submit that upstream.

[girish]

@iamthefij Talking to yourself again ?

[iamthefij]

On another note... There is no Docker image built for MySQL support yet, so I'm writing a new Dockerfile that uses a multi stage built to compile Bitwarden_rs with MySQL support.

[fbartels]

@iamthefij there is one already at https://github.com/dani-garcia/bitwarden_rs/tree/master/docker/amd64/mysql

[iamthefij]

@fbartels yes. But not an image on Docker Hub that I can pull from. Instead I'm building a multistage build that looks a lot like that Dockerfile but with the an LDAP layer and the Cloudron layer.

[fbartels]

@iamthefij it's here https://hub.docker.com/r/bitwardenrs/server-mysql

[iamthefij]

@fbartels well, I guess I didn't look hard enough! (Edit: Looks like the 1.10.0 release was only 2 hours ago. No wonder I missed it. ) It would be good to roll those all into one image with multiple tags, but I can chat with them about that on Matrix.

Anyway, adding the multi-stage build wasn't terribly hard and cuts out an extra dependency on that build pipeline, which is probably a good thing for a security sensitive project.

Latest on my master is now fully operational. Working email, working ldap sync, working MySQL.

BIG WARNING! There is no migration path from SQLite to MySQL. You should export your vault to CSV or something and then re-import it after migration.
