On some ikiwikis that I run, I get the following error on OpenID logins:
no_identity_server: Could not determine ID provider from URL.
I seem recall having that error before, and fixing it, but it always seems to come back and I forget how to fix it. So I'll just open this bug and document it if i can figure it out... -- [[users/anarcat]]
From there we look at `_find_semantic_info()`, which is supposed to hit the OpenID server, but doesn't somehow.... By cranking up debugging, we can see that the consumer fails to verify the HTTPS signature on the host:

And the results vary according to the version of perl:
* wheezy: 1.07 5.014002: 5720
* jessie: 1.10 5.018002: 398

Thanks [jwz](http://www.jwz.org/blog/2014/03/apple-broke-lwp-in-a-new-and-exciting-way-on-10-9-2/) for that.. Mozilla::CA *could* have been packaged in Debian, except it overlaps with the `ca-certificates` package, so it was [basically barred entry](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=702124).
I tried the workaround of hardcoding the path to the CA root, using `PERL_LWP_SSL_CA_PATH=/etc/ssl/certs`, but then I hit *another* bug in LWP: [#738493](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=738493).
Note that this bug is similar to [[bugs/ssl_certificates_not_checked_with_openid/]], but backwards: it checks the SSL certs but then fails to verify.
I filed this bug in the Debian BTS as [#702124](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=702124). Downgrading to wheezy's version of LWPx::ParanoidAgent doesn't fix the problem, instead i get this error:
