I am installed OOD 1.8.12 on CentOS 7.8 and configured it to authenticate using mod_auth_mellon using the provided instructions. https://osc.github.io/ood-documentation/latest/authentication/adfs-with-auth-mellon.html. I am getting an error when I try to authenticate that the post URL does not exist. The ADFS authentication appears to be successful. I am wondering if I missed something on the OOD side. I get a 404 error with this request https://xxxx.xxx.xxx.org/mellon/metadata/postResponse.
The apache log provides this information.
Endpoint “metadata/ls” not handled by mod_auth_mellon.
[Mon Sep 28 11:05:19.781119 2020] [auth_mellon:error] [pid 143499] [client x.x.x.x:56253] Endpoint “metadata/postResponse” not handled by mod_auth_mellon.
My guess is mod_auth_mellon is not configured correctly but I am not sure where to start to debug this. What should apache return for /mellon/metadata/ls and /mellon/metadata/postResponse? Any help is greatly appreciated.
