Allow invalid and Self-Signed SSL not effective for oauth

[Shelnutt2]

I'm testing rocket.cat with gitlab oath. I've got a self signed cert on the gitlab server, and I'm unable to authenticate against it due to the self signed certificate.

{"line":"398","file":"oauth_server.js","message":"Error in OAuth Server: Failed to complete OAuth handshake with gitlab at https://example.com/oauth/token. DEPTH_ZERO_SELF_SIGNED_CERT","time":{"$date":1443438610410},"level":"warn"}

I've tracked this down to to meteor's oath package. I don't think this can be solved easily with the existing configuration option.

I've worked around it by adding NODE_TLS_REJECT_UNAUTHORIZED=0 as en environmental variable to the docker-compose.yml

I am also having this problem. Where can I add that environmental variable on a regular install?

[dalenoe]

This is what I am seeing in the error log.

UNABLE_TO_VERIFY_LEAF_SIGNATURE

I am facing the same problem.

I have solved a similar issue when testing gitlab's embedded mattermost with gitlab as OAuth.

My (legitimate) certificate' authority (RapidSSL) was not in their embedded cacert.pem file. I did not find a proper way of fixing this so I changed gitlab's cacert.pem file with this ugly trick:

# fix gitlab cacert missing rapidssl
echo -e "\nRapidSSLCA-G3\n=============" >> /opt/gitlab/embedded/ssl/certs/cacert.pem && \
cat /etc/ssl/certs/RapidSSLCA-G3.pem >> /opt/gitlab/embedded/ssl/certs/cacert.pem

Using the docker vesion of Rocket.Chat. Is there a way of achieving the same fix (or even a less ugly one) ?

EDIT: @Shelnutt2 's solution is less ugly and works great too :

adding NODE_TLS_REJECT_UNAUTHORIZED=0 as en environmental variable to the docker-compose.yml

I'm having a related issue with an internal version of gitlab. Trying to oauth against gitlab yields the error SELF_SIGNED_CERT_IN_CHAIN, rather than the one (DEPTH_ZERO_SELF_SIGNED_CERT) listed above. Perhaps its related?

I'm having a similar issue with LDAP settings (Using Rocket.Chat with docker). My LDAP server(openLDAP) using SSLMate wildcard certificate.

But when I install Rocket.Chat manually on local server, it is working. Using same LDAP server and configurations.

Have you tried setting the NODE_TLS_REJECT_UNAUTHORIZED to false on the admin panel?

I am also facing a self signed certificate issue when trying to authenticate through a CAS server. I am running 0.45 with the official Docker image. I've supplied NODE_TLS_REJECT_UNAUTHORIZED=0 to the Docker container and I've enabled Allow Invalid Self-Signed Certs in General settings. Still when the authentication happens I get the following error from Rocket.Chat:

rocketchat_cas rocketchat_cas.js:155 CAS ➔ error error when trying to validate: self signed certificate in certificate chain.

Am I missing something obvious?

UPDATE: I've traced this back all the way to https://github.com/kcbanner/node-cas/blob/master/lib/cas.js#L406. I assume the solution there completely ignores the value of NODE_TLS_REJECT_UNAUTHORIZED and that may be the issue.

[sergioloyola]

I have problems too. Since my CAS idp uses self-signed certificates, when I try to authenticate my idp indicates that it was successful, but rocket.chat shows me the following error:

rocketchat_cas rocketchat_cas.js:169 CAS ➔ error error when trying to validate: unable to verify the first certificate

Who had to deal with the same problem ???

[wcgcoder]

@ScOut3R Did you make any progress circumventing the new CAS limitations? I tried passing my root CA to the node-cas module with the ssl_ca option with no luck. This was done by changing the rocket chat cas_server.js and building from source. 😢

Unfortunately, I still had no luck!

[ScOut3R]

@wcgcoder Well, I worked around the issue by buying a trusted certificate for our Rocket.Chat instance.

[wcgcoder]

@ScOut3R Unfortunately, some organizations have internal certificate authorities they're mandated to use (by law).

In other environments, I'd just use let's encrypt to get my certs.

Any plans to solve this issue? I've just encountered it when testing nextcloud oauth.

Have you tried setting the NODE_TLS_REJECT_UNAUTHORIZED to false on the admin panel?

Where in the Admin panel is that?
