Cool! What is your version of the FreeIPA server? It will be important for
further investigation.

That normally means that you have the same value for LDAP attribute twice or
that you are trying to add multiple values for a single valued attribute. I
wonder if we could get better logging, like how exactly the entry looks like
before it is added to LDAP.

But right now, I cannot think about a better way than to updating
/usr/lib/python2.7/site-packages/ipalib/plugins/migration.py
on the FreeIPA server the following way (new print statement)

                try:
                    print entry_attrs
                    ldap.add_entry(entry_attrs)
                except errors.ExecutionError, e:

, restarting the httpd service and sending us the /var/log/httpd/error_log
after the next migration attempt. Maybe Jan (CCed) knows a better way.
