Hi Artur,
I would just like to make sure I am following correctly, comparing your
entries against mine.
Your setup:
...
config.mapAuthRecord.regex.pattern =
^(?<user>.*?)((\\\\(?<at>@)(?<suffix>.*?)@.*)|(?<realm>@.*))$
...
My setup:
…
config.mapAuthRecord.regex.pattern =
^(?<user>.*?)((\\(?<at>@)(?<suffix>.*?)@.*)|(?<realm>@.*))$
…
Should I add the additional 2 “\\” in on my side?
Yes, please try  adding it. In my case I learned about this issue by debugging
the code because the real exception generated by incorrect regexp syntax was
hidden behind  generic error message giving no clues about the true cause.

Your setup:
...
<LocationMatch ^/ovirt-engine/sso/(interactive-login-negotiate|oauth/token-
http-auth)|^/ovirt-engine/callback>
<If "req('Authorization') !~ /^(Bearer|Basic)/i">

I remember I had syntax errors, but mine was changed.
Does this look fine to you?
Yeah, your version looks good too. You have ' instead of  "  so that is ok.

Hi Artur,
Great, I will try the below and let you know. I appreciate your efforts.
Sure, you may report it, I was in such a rush that I only hit “reply” and not
“Reply All”
I do recall that I had to make some changes to the below as the it complained
about syntax errors:
ErrorDocument 401 "<html><meta http-equiv=\"refresh\"
content=\"0; url=/ovirt-engine/sso/login-unauthorized\"/><body><a
href=\"/ovirt-engine/sso/login-unauthorized\">Here</a></body></html>"
</If>
</LocationMatch>
I will let you know the outcome when I change the below as you suggested.
Cheers

I checked your logs and I did not notice anything suspicious.
However, now I recall I made some changes compared to blog post
example:
1) /etc/ovirt-engine/extensions.d/openid-http-mapping.properties
I added escaping in regexp for '\'
...
config.mapAuthRecord.regex.pattern =
^(?<user>.*?)((\\\\(?<at>@)(?<suffix>.*?)@.*)|(?<realm>@.*))$
...
2) /etc/httpd/ovirt-openidc.conf
Escaping for '"' in error document snippet
...
<LocationMatch ^/ovirt-engine/sso/(interactive-login-
negotiate|oauth/token-http-auth)|^/ovirt-engine/callback>
<If "req('Authorization') !~ /^(Bearer|Basic)/i">
Require valid-user
AuthType openid-connect
ErrorDocument 401 "<html><meta http-equiv=\"refresh\"
content=\"0; url=/ovirt-engine/sso/login-unauthorized\"/><body><a
href=\"/ovirt-engine/sso/login-unauthorized\">Here</a></body></html>"
</If>
</LocationMatch>
...
These two issues were most probably caused by the blog site rendering.
You might want to check engine.log (or server.log not really sure which
one was that) for aaa extension initialization logs. They should
appear at the beginning just after restarting engine.
Unfortunately, at the moment I do not have running keycloak setup (I
used to have a local VM) but I will try to find some time to set it up
again once I'm done with another work item that actually consumes
almost entire disk space for my 2 machines)
Please let me know if anything changes after applying these config
changes. It this works for you then I will request the blog post to be
updated.
Do you mind if I keep(re-post) this discussion back to users@ovirt in
case other might have similar issues with keycloak integration?

Hi Artru,
...
...
Thank you for the reply. The post [1] is actually the main source of
...
information I worked from in order top get everything configured. In
...
the post[1] I ran through the whole testing section, and everything
...
works as expected. I can see the VMs etc when using the python
...
script.
...
...
In my case we are not using ldap as a provider, I tried using
...
keycloak directly as a provider, I am not sure if that is where I am
...
going wrong?
...
...
I have attached the last part of the apache ssl_access_log when I
...
tried logging in this morning. I have also attached the engine log.
...
...
Thanks

Hi Everybody,
...
...
...
...
...
Hi Anton,
...
...
...
Has anybody gone the route of using KeyCloak to login to oVirt?
...
...
KeyCloak has been configured and the neccesary configs have also
...
been
...
...
done on the engine. It redirects perfectly from the oVirt Web Login
...
...
page to KeyCloak, but after logging into KeyCloak, I get redirected
...
...
back to the oVirt Web Login. When trying to login again, I get the
...
...
below error:
...
...
...
...
...
...
...
...
server_error: Missing parameter: 'params'
...
...
...
...
Not so long ago I managed to setup ovirt engine with keyloack (using
...
ldap as users provider). Hopefully, I would be able to help you with
...
it.
...
...
There is excellent blog post[1] available. You might also check
...
keycloak+ldap post [2], however, when I was working on the
...
integration
...
I was not aware of if and did not test it.
...
...
The error you mentioned does not really indicate what exactly is
...
wrong
...
but it might suggest that there is some sort of misconfiguration with
...
apache (you need to install and configure mod_auth_openidc as
...
described
...
at [1]). At least that happened in my case.
...
...
In case you have already gone through it you could probably check
...
apache logs.
...
...
Under [1] there is a python script that can be used to check api
...
calls,
...
please update username/password and test it against your environment.
...
...
...
Would it be possible post relevant piece of apache logs together with
...
engine.log ?

I have checked all the logs, but nothing is telling me what exactly
...
...
the issue is.

...
...

If anybody has any idea, please let me know.
