Hi Visvanath,

F5 and Splunk are both software indeed.

I share with Jerry the same hardware and software configuration (Redhat 7 Linux), so I try to help to find the cause of his performance problems

Hi Jerry,

We already had a chat via the messenger here. We experienced the same problems as you describe here and the biggest issues we had was with the network firewalls and load-balancer (F5). We had long query response times and found out with monitoring and researching Splunk logging that a timeout on the load-balancer was causing our long response times in Moodle.

We also had a url in the content that wasn't able to go outside (on the internet), and that finally caused one of our performance problems. Just a few ideas to troubleshoot. With a separated web and database server you sometimes have to dig in these kind of problems (network, caching or database). I suppose you're also using the Redis (or other) caching server on the webserver? Don't use Memcache with php7.1, it isn't supported anymore by PHP.

Hi Callum,

I experience the same problem, authentication succeeds (I see in Debug logging), but the redirect doesn't work. The SimpleSamlPHP login page is cleared and I see several errors after the login with this message: Session: 'session-name' not valid because we are not authenticated.
 Did you get it working in the meantime or anyone else who experienced the same problem?

I'm trying a test with the SAML2 SSO plugin together with SimpleSamlPHP. My SimpleSamlPHP configuration is working now (with an LDAP authentication provider), but how can I integrate this with the Moodle login?  I tested the SAML2 SSO authentication plugin after configuring the parameters and this works.
I use one testuser with auth = 'saml2sso', in my debug logging I see the login succeeds, but I 'm not forwarded to the Moodle home page. It's quite a puzzle to get this working!

Hi Sean,

Maybe this is not relevant anymore, if you enable debug in your simplesamlphp configuration file(config/config.php), you'll get more info in your logging. The integration between Moodle and SAML2 (SSO) isn't easy to configure I experienced myself. Any good postings here in the forums about this subject?
