Hello, I was able to get past this, and I think this bug can be closed. Normally when I install packages from backports I use a command like "apt-get install -t bullseye-backports freeipa-client", but in this case there is no freeipa-client package in the main bullseye package repo. Therefore, I was able to run the command "apt-get install freeipa-client" to install freeipa-client from backports but all dependencies from the non-backports package repos where possible.
Thank you, Shane Frasier
