The setup instructions for Kerberos and sssd authentication are not long at all. If you are on OEL8/RHEL8 the packages/rpms you need, already come with the OS. It is really just configuration or the /etc/krb5.conf file and the /etc/sssd/sssd.conf file, along with an admin account to join the realm.

Kerberos will give you nice passwordless single-sign on, but it indeed requires Linux configuration and the setup instructions are quite long.

What I like about Radius it is so easy, Windows server people start Radius server on their side and you add just a few lines in database sqlnet.ora and done. But it will not give SSO, users still need to type in their Windows password to authenticate.  

There is also an option to install an Oracle password filter on Active Directory side, then Oracle (since 18c) can authenticate directly against AD. I doubt many AD admins agree to this since it is quite invasive.

We aren’t running Oracle on Azure. Our sys admin is saying we can only use Kerberos on Linux.

We use Radius, to authenticate human database users. Very easy to deploy and has worked well over a decade

But will soon move to Azure AD Oauth authentication, to remove the need for creating users and managing their privileges.

We are looking at connecting our Oracle databases to AD so we can centralize user creation and administration. All of our Oracle databases run on Linux. Our Linux sys admins say that they don’t support AD on Linux. Is it still possible to connect to AD without having AD installed in the Linux environment?
