Keycloak - Issues syncing users with LDAP

Question

I installed Openldap in server and after that added the user into the ldap,below screen show show the added user through Apache Active Directory

Now in keycloak i added user federation as a openLdap and its connecting to ldap without any issue,but when i am trying to sync the user i am getting message

Success! Sync of users finished successfully. 0 imported users, 0 updated users

So no user import from ldap to keycloak ,below is the related ldap connection information in keycloak .

Answer 1

Thanks to @EricLavault and one of company colleague at last Keycloak able to import the user successfully. Below changes i have done to fix the issue.

1. Change the User Object Classes=*
2. Created a new entry ou=People then created user under it
3. In Keycloak used Users DN = ou=user,ou=people,dc=suredev20

After this its start throwing below exception

ERROR [org.keycloak.storage.ldap.LDAPStorageProviderFactory] (default task-1931) Failed during import user from LDAP: org.keycloak.models.ModelException: User returned from LDAP has null username! Check configuration of your LDAP mappings. Mapped username LDAP attribute: uid, user DN: cn=subodh123,ou=user,ou=People,dc=suredev20, attributes from LDAP: {sn=[joshi123], cn=[subodh123], createTimestamp=[20191118180647Z], modifyTimestamp=[20191118180647Z]}

Which is fixed by using Username LDAP attribute = cn as ldap username Attribute description in openldap case bydefault cn
