I guess you mean using ACO (https://accounts.centos.org) as the central
users DB ?
Actually CBS is using certificates issued from ACO directly, so it's
already integrated (and people are granted/removed rights automatically
at the cbs/koji level depending on their group membership in ACO)

For existing resources within centos.org that we deployed before ACO was
available, those were configured to use their built-in users DB. So we
can invest time to see which are the possibilities to be tied to ACO but
it needs at least some glue, like for example token/oauth. Actually, ACO
on its own can't do that (nor is "ldap" compatible) so we need to setup
something in between (like what's done for the Fedora project) to do
that, like either ipsilon (https://ipsilon-project.org/) or keycloak

But the remaining issue would then be to have *everybody* signing
through ACO to get an account that will match with each deployed
applications (like MantisBT for bugs.centos.org and so on). So you can
imagine the impact
