Some problem appears when importing openldap schema with an attibute and an objectclass having the same alias.
Colliding attributeType and objectClass names not supported
Yes, this is a known issue. We have a fix for that, but it will take a bit of time to inject it into Studio.
Anyway, thanks for having reported the issue, as we forgot to create a JIRA for that.
It has been fixed.
Version 2.0.0 M1 has been released.
Closing the issue.
