Azure VMs use Traffic Manager/OpenLogic in CentOS-Base repo, causing rpmup to fail

Symptoms

Microsoft Azure's CentOS VM template appears to use their 'Traffic Manager/OpenLogic' system for the CentOS-Base.repo. If the repository is missing certain packages, it can cause multilib errors when yum is updating.

Description 

We are seeing updates failing on certain Microsoft Azure systems when the libsss_idmap package is being updated. It attempts to pull in an updated version of the sssd-client package, however the 'Traffic Manager/OpenLogic' mirror does not have the package available. 

The following error may be seen:

Protected multilib versions: libsss_idmap-1.16.5-10.el7_9.11.x86_64 != 
libsss_idmap-1.16.5-10.el7_9.10.i686
Error: Protected multilib versions: libsss_nss_idmap-1.16.5-10.el7_9.11.x86_64 != 
libsss_nss_idmap-1.16.5-10.el7_9.10.i686
(XID 3gh5tj) “/usr/bin/yum” reported error code “1” when it ended:

Workaround

The workaround would be to utilize a different mirror, for example:

/etc/yum.repos.d/CentOS-Base.repo
