Ok, I think I misguided you with the second DN, the real DN should be
"cn=ipa-ldap-delegation-targets,cn=s4u2proxy,cn=etc,dc=ddistrict,dc=int", see
/usr/share/ipa/replica-s4u2proxy.ldif for the LDIF that is being loaded.

The key here is to check the error message of ldapmodify that was run on the
failing replica, try to search in /var/log/ipareplica-install.log.
