No, I just realized that the error happens even before the child is
called. It looks like some unexpected data is received.

I wonder if you can try to following using gdb after installing the sssd
debuginfo file?

    gdb -p $(pidof sssd_be)
    (gdb) break ad_gpo_parse_machine_ext_names
    (gdb) continue

try to authenticate while keeping gdb running, whenever gdb show the
prompt again please type

    (gdb) bt full
    (gdb) continue

until the authentication finally fails. Please send me the gdb output.

If this won't work for you I can try to prepare an instrumented build
for you which writes the needed data into the logs. For this I need to
know the exact version of the SSSD package you are using.

bye,
Sumit
