Problem with new installation

Get Help
1

I have a new install of OOD v4.0.8 which I am installing from scratch on a RHEL9.6 – which I am performing strictly following the instructions at Installation — Open OnDemand 4.0.0 documentation (besides authentication, which is done with LDAP/Dex in the same way I did for an older version which works just fine).

The authentication seems to be working (wrong user/passwd are rejected, good ones are let in), however upon successful login I get

Looking at /var/log/httpd/<URL redacted>_error_ssl.log I see the following, which does have a few strange things

namely:

  • it uses localhost rather than the actual URL in a few places
  • has my username with an uppercase (but I suspect that is an ActiveDirectory-ism and I have seen it in other contexts too where it did not cause issues there)
  • tries to open a socket against port 80 which fails (if I point my browser to that URL that gets redirected to port 8443 and is not found either)
  • /var/run/ondemand-nginx/ exists but does not have any subdirectory under it

I suspect I missed a step in the instructions I followed, because looking ahead in reference and tutorial sections they seem to imply that the /etc/ood/config/ondemand.d/ and /etc/ood/config/apps/ exist (for example at PUN environment — Open OnDemand 4.0.0 documentation and ondemand.d/*.yml files — Open OnDemand 4.0.0 documentation ) whereas those paths do not exist in my install:

On the other hand /var/www/ood/apps/ does exist and appears to be populated by the usual stuff

So I am not sure what may be wrong here?
