1 On some ikiwikis that I run, I get the following error on OpenID logins:
3 no_identity_server: Could not determine ID provider from URL.
5 > Is this fixed now that [[!debbug 738493]] has been fixed? --[[smcv]]
7 > > No, it isn't. I still get: `no_identity_server: Could not determine ID provider from URL.` from the latest ikiwiki in jessie (3.20140831), with liblwpx-paranoidagent-perl 1.10-3. Debugging tells me it's still related to the `500 Can't verify SSL peers without knowing which Certificate Authorities to trust` error, so probably because `Mozilla::CA` is not packaged ([[!debbug 702124]]). I still had to apply the patch to disable SSL verification at the end of this file. However, setting `$ENV{PERL_LWP_SSL_CA_PATH} = '/etc/ssl/certs';` seems to work now, so the following dumb patch works:

24 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]]
26 The Perl module manual says:
28 > "no_identity_server"
29 > (CV) Tried to do discovery on a URL that does not seem to have any providers at all.
31 Yet on the server side, I see no request coming in on the OpenID provider...
33 Adding debugging helps in figuring out wtf is going on:

59 There are three places in the code the original error message happens:
61 * Net::OpenID::claimed_identity
62 * Net::OpenID::verified_identity
63 * Net::OpenID::_find_openid_server
65 We'll look at the last one because it's where the URL data is actually fetched.
68 sub _find_openid_server {
69 my Net::OpenID::Consumer $self = shift;
71 my $final_url_ref = shift;
73 my $sem_info = $self->_find_semantic_info($url, $final_url_ref) or
76 return $self->_fail("no_identity_server") unless $sem_info->{"openid.server"};
77 $sem_info->{"openid.server"};
81 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:

91 To get this little wonder, I had to change the `_find_semantic_info()` as followed:
94 sub _find_semantic_info {
95 my Net::OpenID::Consumer $self = shift;
97 my $final_url_ref = shift;
99 my $doc = $self->_get_url_contents($url, $final_url_ref);
100 $self->_debug("url dump ($url, $final_url_ref) = " . $doc) if $self->{debug};
101 my $info = _document_to_semantic_info($doc);
102 $self->_debug("semantic info ($url) = " . join(", ", map { $_.' => '.$info->{$_} } keys %$info)) if $self->{debug};
108 A minimal test case would be:
111 perl -e 'use LWPx::ParanoidAgent;
112 print $LWPx::ParanoidAgent::VERSION, " $]: ";
113 print length(LWPx::ParanoidAgent->new->get
114 ("https://id.koumbit.net/anarcat")
115 ->decoded_content), "\n";'
118 And the results vary according to the version of perl:
120 * wheezy: 1.07 5.014002: 5720
121 * jessie: 1.10 5.018002: 398
123 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).
125 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).
127 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.
129 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:
131 500 Can't read entity body: Resource temporarily unavailable
133 ... yet the commandline client works fine... I'm out of ideas for this sucker.
135 Update: i found a way to reproduce the problem even with LWPx::ParanoidAgent 1.07:
138 $ perl -e 'use LWPx::ParanoidAgent;
139 print $LWPx::ParanoidAgent::VERSION, " $]\n";
140 $ua = new LWPx::ParanoidAgent; for (my $i = 0; $i< 10 ; $i++) { $c = LWPx::ParanoidAgent->new->get
141 ("https://id.koumbit.net/anarcat")
142 ->decoded_content; if (length($c) < 100) { print $c; } else { print length($c),"\n";}}'
145 500 Can't read entity body: Ressource temporairement non disponible
146 500 Can't read entity body: Ressource temporairement non disponible
147 500 Can't read entity body: Ressource temporairement non disponible
148 500 Can't read entity body: Ressource temporairement non disponible
149 500 Can't read entity body: Ressource temporairement non disponible
