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">

 

Require valid-user
AuthType openid-connect

ErrorDocument 401 "<html><meta http-equiv=\"refresh\"content=\"0; url=/ovirt-engine/sso/login-unauthorized\"/><body><ahref=\"/ovirt-engine/sso/login-unauthorized\">Here</a></body></html>"
</If>
</LocationMatch>

 

My setup:

<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>

 

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. 

Thanks

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?
