How to change attribute used for DN of users?

[umnaut]

Hello. I am trying to set up azuread-ldap-wrapper so that users can bind using their full upn instead of samaccountname.

However, since uid is pulling from samaccountname and each user's dn uses uid=samaccountname,+base dn I can only bind using samaccountname.

I tried using a ldap_customizer for this, but DN isn't exposed as an attribute of an ldapuser:

'use strict';

const config = require('../src/config');
const helper = require('../src/helper');

var customizer = {};

customizer.ModifyLDAPUser = function (ldapuser, azureuser) {
    helper.log("customizer", "ModifyLDAPUser", "called", "custom");

    if (azureuser && azureuser.userPrincipalName) {
        let newUid = azureuser.userPrincipalName.toString();

        ldapuser.uid = newUid;

        if (ldapuser.entryDN && ldapuser.entryDN.startsWith("uid=")) {
            let parts = ldapuser.entryDN.split(",");
            parts[0] = `uid=${newUid}`;
            ldapuser.entryDN = parts.join(",");
        }

        if (ldapuser.dn && ldapuser.dn.startsWith("uid=")) {
            let parts = ldapuser.dn.split(",");
            parts[0] = `uid=${newUid}`;
            ldapuser.dn = parts.join(",");
        }

        helper.log("customizer", "uid set to", ldapuser.uid);
        helper.log("customizer", "entryDN", ldapuser.entryDN);
        helper.log("customizer", "dn", ldapuser.dn);
    }

    return ldapuser;
};

module.exports = customizer;

How can I alter my deployment so that I can bind and auth using something like ldapsearch -x -D "[email protected],cn=users,dc=private,dc=local" instead of ldapsearch -x -D "uid=test,cn=users,dc=private,dc=local"

That should already work as expected without customizing anyting. If the uid does not exist, it looks for it in the AzureADuserPrincipalName attribut, which usually is the email address/full upn.
