Description

I looked into this a bit. It appears that all of the freeIPA authentication bits are configured to set internal apache variables, and mod_passenger would be able to read them as environment variables on each request. Because puma is being used as a generic http proxy via mod_proxy, no information about the intercepted form logins or kerberos auth makes its way to foreman through puma.

All of this needs to be reworked with puma in the mix. None of the existing IPA logic will work. (Check headers, not env if puma is used, etc).

This corrects a typo in the previous change, which unset
REMOTE_USER_USER_GROUPS instead of REMOTE_USER_GROUPS in the apache
configuration.

History

#1 Updated by Steve Jacobs 6 months ago

What I did to check this:

Turned up debug logging in apache and installed mod_dumpio.

I can verify that auth is occurring, and the ifp service is delivering email, etc.

mod_dumpio trace shows that no REMOTE_USER, etc header is being sent to puma on port 3000.

  • Project changed from Foreman to Installer

With 2.1 you can revert back to passenger using --foreman-passenger true. I consider that a workaround, not a solution since long term we want to align on Puma and this is a feature we support. This is something in the installer, so moving to the correct project.

I have fixed this by changing app/services/sso/apache.rb to use HTTP_REMOTE_USER instead of REMOTE_USER and setting HTTP_REMOTE_USER in apache. I have created pull requests to foreman and puppet-foreman projects in case this is acceptable.

Have you actually tested this? I have tried this with many variations and never got it to work. Tested on RHEL8.

#6 Updated by Hesham Ahmed 5 months ago

I have tested this and it works fine on EL7

#7 Updated by Adam Winberg 5 months ago

Ok, got it working. But when using mod_ssl the request header statement need to look a bit different:

RequestHeader set REMOTE_USER %{REMOTE_USER}s

Notice the ending 's' instead of 'e' to make it work with mod_ssl
