Hello everyone,
I have configured a web application, that is running in Tomcat, to
authenticate users with Keycloak. Everything is running fine if I
deploy the app to my local Tomcat, even when using the remote Keycloak
instance.
However, when I deploy the app to another Tomcat running behind an
Apache HTTP Server, the following happens:
* When I navigate to https://my-domain.tld/app I get redirected to the
Keycloak login
* After I log in successfully, Keycloak redirects me to
<IP>:<PORT>/app of the Tomcat
* The Tomcat answers with HTTP status 400
My keycloak.json looks like this:
{
"realm": "cdb_test",
"auth-server-url": "https://keycloak-server.tld/auth",
"ssl-required": "external",
"resource": "cdb_test",
"public-client": true
}
The VHost is configured like this:
ProxyPass /app http://<IP>:<PORT>/app/
ProxyPassReverse /app http://<IP>:<PORT>/app/
ProxyPassReverseCookiePath / /app/
I turned on debug logging for the Keycloak Tomcat adapter, see attachment.
Any advice?
Thanks in advance

Hello Timo,
Perhaps enable tomcat access logging [1] can help you to debug this issue.
You can compare the request with mod_proxy with the one without.
Out of curiosity: why do you need to set ProxyPassReverseCookiePath / /app/
?
Hope it helps,
Luis

Hello Luis,
thanks for your reply!
I was able to get a step further... I think.
I added "ProxyPreserveHost On" to the VHost configuration. Now
Keycloak redirects me to http://my-domain.tld/app (http without s)
after the login. Something (I haven't figured out wether it's the HTTP
Server or the Tomcat) redirects from HTTP to HTTPS after which the
Tomcat returns 403 and prints the following message to the log:
{"error":"invalid_grant","error_description":"Incorrect
redirect_uri"}
I guess the problem is the redirect to HTTP instead of HTTPS? I tried adding
RequestHeader set X-Forwarded-Proto "https"
to the VHost configuration but that didn't help. Any further advice?
Btw, I didn't write the inital VHost configuration,
"ProxyPassReverseCookiePath" was there when I started working on it.
Probably from some template.
Thanks in advance
Timo

Hello Timo,
You have a couple of options:
- Use https in your apache mod_proxy configuration (ProxyPass /app https://...)
This implies to have the SSLProxyEngine on with
the SSLProxyCACertificateFile poiting to your CA certificate See the
mod_ssl docs for more details on this [1] For a PROD installation that
would be my preferred option
- For testing quickly you can always try to cheat keycloak adding
scheme="https" to your HTTP connector in tomcat [2] Me I do this for
cheating the SAML adapter ;) [3]
Hope it helps,
Luis

Timo,
To secure a Tomcat webapp that is behind an SSL-terminating reverse proxy, you basically
need a checklist of three items:
- make sure that your reverse proxy forwards all the necessary info to the backend,
including hostname and protocol;
- in Tomcat, configure proxy (host and "https" scheme) on a connector level;
- reflect the changes in the client config in Keycloak (use https:// and your proxy URL).
Cheers,
