With the fact that CentOS 8 is EOL and no longer on mirrors, I can not duplicate this. It looks like you have an idm module installed and it is needing things which the best bind in your repo does not have. Try the following:

dnf --nobest <whatever you were doing to install> 

and see if that fixes it any. After that, I would suggest looking to move to an alternative distribution (in alphabetical order):

Alma Linux

Oracle Linux

Red Hat Enterprise Linux

Rocky Linux

or in reverse order

Rocky

Red Hat Enterprise

Oracle

Alma

For tracking newer features which will show up in the next major Red Hat Enterprise Linux

CentOS Stream 8
