I want to create an entry with domain objectClass. The only MUST attribute required by this objectClass is the domainComponent or dc. The schema definition allows use of both these names, but the entry creator tries to be smarter. When I specify the DN as dc=subdomain,dc=example,dc=com in the third step of creating a new entry and go to the last step, the entry editor lists the dc attribute in normal font and makes me enter the domainComponent which is listed in bold font.
So I end up with both dc and domainComponent attributes to make the "Finish" button active. Because the dc attribute is the part of the dn I cannot delete it, because the entry creator thinks that I still have to enter the domainComponent attribute I cannot delete it neither. When I finish creating the entry the server responds with a "Error while creating entry [LDAP: error code 20 - attribute 'dc' provided more than once] " error.
