WSO2 APIM 4.0.0 - Groups are not assigned to Users - ldap

Question

I'm trying to configure API Manager 4.0.0 against OpenLDAP.
The users and groups are correctly fetched from the ldap and I can see them on carbon UI.
When I navigate to "View Users" of one group, I can see the users that are fetched using the attribute "uniqueMember" of the ldap.
But when I navigate to "View Roles" of one user, only "Internal/everyone" is displayed. The groups of the user are not assigned to him.
Is it normal to see the relationship in one way only ?
My OpenLDAP has no "memberOf" attribute schema. Maybe it is required ?
I am using a fresh install from wso4am-4.0.0.zip all-in-one without modification.
Here is the configuration of the userstore:

Answer 1

FYI I found the answer after activating logs :
DEBUG
{org.wso2.carbon.user.core.ldap.UniqueIDReadOnlyLDAPUserStoreManager} - No UserID found for the property: uid, value: user1, in domain: COMPANYUSERS
My user was incorrectly fetched because of scimId not exists in my Ldap
<Property name="UserIDAttribute">scimId</Property>
I changed to uid and it is working now.
<Property name="UserIDAttribute">uid</Property>
