Proxying RHEL repositories is an important use case for yum repositories.
We've added support for SSL client certificate authentication in Nexus Repo 3.20.0 (
NEXUS-12488). This is needed for proxying RHEL yum repositories. However, it is not clear if it is by itself sufficient. And I can find no documentation on how this can be done.
I'd like to see us test this against both regular RHEL and RHEL on AWS. The procedure for setting this up should be documented, and if problems are found, issues should be filed so they can be prioritized.
