Hm, the match failure must be on user name. What certificate are you
using on the client side, and what user name does pgrepmgr_nonprod_map
map it to? Does it succeed if you weaken the hba entry to
hostssl replication all 100.0.0.0/8 cert map=pgrepmgr_nonprod_map

Should be. But you might find it easier to debug the auth failure
in a non-replication context, ie add
hostssl all pgrepmgr_nonprod 100.0.0.0/8 cert map=pgrepmgr_nonprod_map
and then see if you can connect with the same credentials from psql
or your favorite other client.
BTW, don't forget you have to signal the postmaster to reload
configuration after any change in these files.
