[Koha] SSO Shibboleth & oauth issues

Fri Jun 30 13:22:08 NZST 2023

We’re everywhere! 

Well, the good news is that I’ve reproduced your error when testing OIDC on the master code branch. 

But the bad news is that I’ve reproduced your error when testing OIDC on the master code branch.

I haven’t tested the Shibboleth integration yet as it’s more work to set up, but it could be related. 

The OIDC is working fine in 22.11.03, so it looks like it was broken between 22.11 and 23.05. 

I’ll look at fixing this one. (Authentication is a special interest of mine, so I’m usually a good person to ask about these things.)

But if you can check the Koha logs for anything obvious for your Shibboleth issue in the meantime – that would be helpful.

Hey David,

It's good to know there is a Koha community active so close to us!

Great.

So we're running 23.05 on Debian Bullseye installed using apt.

I'll have a look through Koha's logs. We're using OAuth as an alternative, using the same IdP.

Hey Justin,

Sorry to hear you're having issues, but great to see another organisation in NSW using Koha!

Let's see if we can help you sort out this issue. What version of Koha are you running, how did you install it, and on which Linux distro? 

With the Shibboleth, you'll want to look at your Koha logs. With the other auth, are you using OAuth or OIDC?

Hey everyone,

I am Justin from the Tenants’ Union of NSW. Lovely to meet you all, albeit
in an archaic manner.

There is a Koha issue I am having trouble resolving…

It’s a strange issue with Shibboleth and now I think the same issue
displayed differently with oauth (that I wanted to implement as an
alternative), both using the same IdP, and definitely isolated to Koha
and/or the server running it. I believe it’s a caching issue of some sort…

When I get redirected back to Koha after a successful login with
Shibboleth, I get a HTTP 500 error, with this console output, unsure if
actually related or not:

(index):6577 crbug/1173575, non-JS module files deprecated. (anonymous) @
(index):6577

Refreshing the page redirects once again with a successful login.

Oauth has a similar issue. I am redirected back to Koha after a
successful login with the identity provider and I am greeted with an error
message:

> There was an error authenticating to external identity provider:
> wrong_csrf_token

Refreshing doesn't fix it but clicking the IdP login link again redirects
back with a successful login and token.

My theory is the redirect is happening too quickly before the token is
actually retrieved.

I've looked in Shibboleth's logs and have yet to see anything obvious.

Thanks in advance,
Justin Dowswell
