rootless podman: how to integrate with AD/SSSD instead of configuring in /etc/subuid /etc/subgid？or how to handle the permission issue which caused by without configuring /etc/subuid(subgid)?

Issue Description

==========================
hi experts

we have scenairo like:

we have HPC cluster(linux redhat9), which scheduled by IBM LSF
we try to config rootless podman, but we do not want to add users to the /etc/subuid /etc/subgid file directly, since we have a lot of users which authenticated by sssd+AD
but without configuring /etc/subuid(subgid) , there are a lot of permission problem
my question are:

Is there any suggestion like to integrate with sssd/AD without configuring /etc/subuid(subgid)?

Is there any way to fix this permission problem? to let it work as configured in /etc/subuid(subgid)?

Any suggestions will appreciate
Thanks in advance.
