I am not able to install REALMD on Red Hat 6.8 VM hosted in Azure. I have even configured EPEL repositories using this link. Without this package we are not able to join the linux VM to our domain as described in this Official Link on RedHat or this link on Azure (where our VM is located).
I have internet connectivity on the VM and I am able to install other packages.
Any Pointers as to where to look or what to check.
realmd is not supported in RHEL 6, you should upgrade to RHEL 7 in order to use it. I've seen this confirmed at https://access.redhat.com/solutions/2273711, although I think it requires logging in to Red Hat customer portal.
