Federated LDAP add user not working

We have an ADLDS ldap that we’re federating to. When trying to add users, we see a message that the user can’t be created.

ERROR [org.keycloak.storage.ldap.idm.store.ldap.LDAPOperationManager] (default task-9) Could not query server using DN [cn=willtiwork,DC=shadlds,DC=corp] and filter [(cn=willtiwork)]: javax.naming.NameNotFoundException: [LDAP: error code 32 - 0000208D: NameErr: DSID-03100241, problem 2001 (NO_OBJECT), data 0, best match of:
‘DC=shadlds,DC=corp’

When we check the backing store for the LDAP, we find the user has been created. How to resolve?
