I have just installed Open OnDemand on a RHEL 7.7 server following the instructions under “Install Software from RPM”. I am on section 4 “Start Services”. I’m on the last step where I’m using a browser to try and access the Open OnDemand dashboard. Whenever I try to navigate to the server in a web browser, I get an HTTP 500 error. I see the following error in the apache logs:
oidc_authenticate_user: the URL hostname (host1.internal.edu) of the configured OIDCRedirectURI does not match the URL hostname of the URL being accessed (apps.cluster.edu): the "state" and "session" cookies will not be shared between the two!
host1.internal.edu is the internal domain name of the machine (changed for security)
apps.cluster.edu is the external FQDN that users will use to access Open OnDemand (changed for security).
I’m not sure how to resolve this issue. Any assistance would be greatly appreciated.
Hi and welcome!
Looks like you need to specify the oidc_provider_metadata_url (I believe we used the FQDN by default, which is what you have).
Here’s documentation on other OIDC configs you can set in ood_portal.yml.
https://osc.github.io/ood-documentation/latest/reference/files/ood-portal-yml.html#configure-openid-connect
Jeff,
Thanks! I set that value in ood_portal.yml. I then ran the following:
/opt/ood/ood-portal-generator/sbin/update_ood_portal
systemctl restart httpd24-httpd.service httpd24-htcacheclean.service
systemctl restart ondemand-dex.service
However, the exact same error still persists. I’m trying to set up LDAP authentication.
Got it. Sorry I misread that too and jumped to something. You’re using Dex + LDAP? If you’re just using LDAP you don’t need any of that OIDC stuff (though i have to warn you now that apache’s LDAP is very insecure).
If you’re going Dex + LDAP route - I think that you need to set servername to apps.cluster.edu (again in ood_portal.yml.
I was planning on using Dex + LDAP. I have the Dex section configured for LDAP. I have servername set already. Is there something else I’m missing?
Do you have client_id set? Looks like there’s some conflict here. You could either just remove it (it’ll default to servername) or set it to apps.cluster.edu.
This is how we’re building that URL.
client_id was set. I’ve removed it and done the three steps above to regenerate files and restart apache. The same error still persists.
Are you restarting dex when you bounce things?
I believe so. This is one of the commands I’m running:
systemctl restart ondemand-dex.service
Cool - also let’s be sure it’s the same error you’re getting around OIDCRedirectURI. It could be a new error.
Yep. It’s the exact same.
Can you share your ood_portal.yml removing anything that’s sensitive.
Jeff,
See below. Sensitive information removed.

You know hashtags # are comments in YAML right?
Meaning none of those configurations are being picked up.
I did not. That’s embarrassing. I thought because they had default values that it had to be formatted that way. I will go fix that right now.
All good! I knew at this point it has to be something we’re overlooking.
Let me know if you have any more issues!
Thanks! I’ve uncommented some of the values and I’m now getting: Bad request. Invalid client_id (“apps.cluster.edu”)
It must not like this empty client_id? You can keep both of those commented. The name I think is just a UI thing, but I’d guess it’s getting tripped up on client_id.
Jeff,
I’ve tried uncommenting and setting client_id but it doesn’t seem to change anything. Below is the dex section with sensitive info removed. Can you check and see if you see anything wrong?
