WSO2 Identity Server external LDAP throws OBJECT_C

I am using the Identity Server 4.1.0 and also I am running an ApacheDS within the Apache Directory Studio. So what I want now is connect my IS to the external LDAP.
IS is connecting fine to the ldap, only it throws errors because there are attribute-definitions missing. At least that is my interpretation of the stacktrace.
I saw that other people tried it too:
WSO2 external ldap not working But my error is different.
Also I see how in this blog it is explained well how to use the Directory Studio, but it seems it is all running on the embedded LDAP of the IS:

Any help is appreciated! Thanks in advance
Best, Johannes

This is because WSO2 IS uses set of customized object classes in order to achieve some tasks such as SCIM. Since you are using en external LDAP either you can change the schema of the LDAP or you can map those attributes using claim mappings.

Since you are using ApacheDS, you can use the LDIFs to change the schema of your LDAP. You can find ldif files under /repository/data/org.wso2.carbon.directory/schema/ou=schema

If you do not wish to change the schema, easy way is to change the claims. For example, you have got an error saying 'accountlock' doesn't exists. This means IS trying to insert some value to a attribute within LDAP. Attribute name is 'accountlock'. This is controlled from claim mappings (Home > Configure > Claim Management in IS). There you can find set of claim dialects are displayed.

If you go in to these dialects, you can find set of claims are there. I take the accountlock attribute as an example. Under http://wso2.org/claims dialect, you can find 'Account Locked' attribute is there. You can change the value (Mapped Attribute) of that claim to an existing attribute in youe LDAP. This existing attribute needs to be a string type attribute. This process can be repeated for each missing attribute.

Hope this helps
