[users@httpd] Proxy with ssl backend server
Hello,
I am trying to use apache as a proxy to pass requests to a https backend like this:
<VirtualHost *:443>
SSLProxyEngine on
ProxyPass /service/ https://backend.do.main:4434/service
ProxyPassReverse /service/ https://backend.do.main:4434/service
ProxyPassReverseCookiePath / /service/
ProxyHTMLURLMap https://backend.do.main:4434/service /service
<Location /service/>
SetEnv force-proxy-request-1.0 1
SetEnv proxy-nokeepalive 1
SetEnv proxy-sendcl
ProxyHTMLEnable On
ProxyHTMLExtended On
LogLevel Debug
ProxyHTMLURLMap https://backend.do.main:4434/service/service/
RequestHeader unset Accept-Encoding
AuthName "Application /service"
AuthType Basic
AuthUserFile /m/b/httpd/passwd
AuthGroupFile /m/b/httpd/group
Require group service
SSLRequireSSL
RequestHeader set Authorization "Basic 123456778"
RequestHeader set X_FORWARDED_PROTO 'https'
</Location>
</VirtualHost>
This works fine for http backends, but with https, I get following errors:
[Thu May 25 13:34:04.690065 2023] [proxy:debug] [pid 2259] mod_proxy.c(1245): [client 109.43.178.5:13845] AH01143: Running scheme https handler (attempt 0)

I guess, the reason for this problem might be that the backend server uses
a self signed certificate created like this:
openssl req \
-new -newkey rsa:4096 \
-subj /C=DE/CN=backend \
-addext subjectAltName=DNS:backend.do.main \
-addext certificatePolicies=1.2.3.4 \
-x509 -nodes \
-days 3650 \
-out server-cert.pem \
-keyout server-key.pem \
I tried disable certificate check by addin following options, but the did
not help:
SSLProxyVerify none
SSLProxyCheckPeerCN Off
SSLProxyCheckPeerName Off
SSLProxyCheckPeerExpire Off
Any ideas what might be wrong with my configuration?
How could I explicitly install the backend certificate as "trusted"?
I tried SSLProxyMachineCertificatePath, but also without success.

This looks like https://bz.apache.org/bugzilla/show_bug.cgi?id=62232
which was fixed in httpd-2.4.34.

I don't think it has to do with the certificate generated/configured
on the backend side. This error happens at the creation of the SSL
connection, no communication with the backend yet.

I don't know which version/patches of httpd is shipped with
opensuse-Leap-15.1 (httpd-2.4.33 possibly?), but the configuration
above seems to work with the latest/upstream httpd-2.4.57 release.
Maybe you can give the latest opensuse-Leap a try (15.4 or 15.5 seem
to ship httpd-2.4.57)?

Yes. This is why I suspect it has to do with the way I generate the
self-signed certificate:
openssl req \
-new -newkey rsa:4096 \
-subj /C=DE/CN=backend \
-addext subjectAltName=DNS:backend.do.main \
-addext certificatePolicies=1.2.3.4 \
-x509 -nodes \
-days 3650 \
-out server-cert.pem \
-keyout server-key.pem

This is not built by myself. All is stock opensuse-Leap-15.1
Apache serves happily SSL to the clients. Only backend servers are not
working.

Do you build httpd by yourself? Which OS / httpd / openssl version? It
looks like httpd (mod_ssl) links/runs against an openssl version
different from the one it's been built with.
