Hi all,
I've change allowIDN attributes in src/register/nsset.h and src/register/domain.h to yes in fred-server-2.1.11.

Then:
#fred-admin --zone_add --zone_fqdn=xn--mgbx4cd0ac
#fred-admin --registrar_add_zone --zone_fqdn=xn--mgbx4cd0ac --handle=REG-UMAR
#create_domain xn--mgbkp7dn3c.xn--mgbx4cd0ac CID:001 NULL CID:001 NULL (12 m)
ERROR: Authentication error

How can I solve this IDN error and successfully create an IDN zone?

Thank you.
