The username/password for the admin LDAP config is correct. IDEAS, SUGGESTIONS?

var ad = new ActiveDirectory({ url: 'LDAP://LDAPAUTH.LDAP.< MYDOMAIN >.org',
        baseDN: 'OU=SystemUsers,DC=< OUR >,DC=< DOMAIN >DC=local',
        username: '< VALIDUSER >',
        password: ' <VALID PASSWORD>' });

    var username = '< TESTUSERNAME >' ;
    var password = '< TESTPASSWORD >' ;

    ad.authenticate(username, password, function(err, auth) {
        if (err) {
            console.log('ERROR: '+JSON.stringify(err));
            return;
        }

        if (auth) {
            console.log('Authenticated!');
        }
        else {
            console.log('Authentication failed!');
        }
    });

ERROR: {"dn":"","code":49,"name":"InvalidCredentialsError","message":"80090308: LdapErr: DSID-0C0903A8, comment: AcceptSecurityContext error, data 52e, v1db1\u0000"}

gheeres. THANK YOU sir for the response, using the userPrincipalName was the “issue”.

The error says that the credentials are invalid. That’s being returned FROM the server.

Do you have any special characters in the username or password you are using? Those may need to be escaped. Check the DC (Domain Controller) logs that you’re authenticating against.

Also are you using a DN, a sAMAccountName or a userPrincipalName for the username? I recommend using a userPrincipalName.
