Security bulletin: Passwords of Domino Internet users are vulnerable  

By Martijn de Jong | 2/22/24 1:23 AM | Infrastructure - Notes / Domino | Added by Roberto Boccadoro

The official title of the security bulletin is: “HCL Domino is susceptible to a weak cryptography vulnerability (CVE-2023-37495).” The problem is with person documents that were created using the “Add Person” button in the Domino Directory. For people less savvy in Domino: that’s not the usual way to add users to Domino. In Domino, we register users using a certifier file. The only time we add persons to the Domino Directory using the “Add person” button, is when we know that these users will only ever access a Domino application through a web browser. The problem with these “internet users” is that the hash in the Domino Directory for the HTTP password uses a cryptographically weak hash algorithm. If an attacker has access to these hashes, he could determine the user’s password through a brute force attack. You can’t see these hashes from a browser, so the attacker needs to have access to the Domino Directory through a Notes or Nomad client. That limits the potential attackers to all users who are registered as Notes users inside the company.

Auth0 ODIC OpenID with Domino & Some other interesting findings  

By Daniel Nashed | 2/22/24 1:21 AM | Infrastructure - Notes / Domino | Added by Roberto Boccadoro

We are working on a ODIC setup with a German business partner for a larger German customer. Auth0 is one of the major providers. We got it working but only with some tricks for now. It turned out the Auth0 OIDC endpoint has a cache expiration for 15 seconds. This looks like a setting that can't be changed. The Domino OIDC cache uses the expiration header to invalidate the cache. So our cache on the Domino side was constantly reloading and invalid in some cases. You really have to have an expiration that is at least a couple of minutes. Better at least 1 hour. Faking the cache expiration This has been reported to HCL and the team is working on an enhancement. Meanwhile I came up with a work-around setting up a Fake provider on a NGINX server to forward the requests.

Attention, REST service user!  

By Oliver Busse | 2/22/24 1:19 AM | Development - Notes / Domino | Added by Roberto Boccadoro

I lately came across a problem with Domino 14, but it turned out that this issue applies to 12.0.2 FP3 as well. When you use the REST service control from the Extension Library to provide a custom REST service, you will get an exception which has nothing to do with anything in your XPage or your Java code. The root cause is yet to be examined, but the defect article is already up:

Running offline activities on databases with Domino V14   

By Rainer Brandl | 2/22/24 1:16 AM | Infrastructure - Notes / Domino | Added by Roberto Boccadoro

Last week I migrated a HCL Domino V11 server to V14 and tried to run the compact task to upgrade the databases to ODS55 but received the following error:HCL Notes: error 0x1F3After some investigations and a very helpful hint of the HCL Support I could modify my existing script because due to the structural change in HCL Domino V14 the NOTES.INI now is located in the Domino\Data directory and so you have to run an offline compact this way: – Stop the HCL Domino Server – Change to the Domino\Data directory – [dominoprogramdirectory]\ncompact.exe -ODS -# 4

Domino Backup/Restore with multiple configurations and targets  

By Daniel Nashed | 2/22/24 1:14 AM | Infrastructure - Notes / Domino | Added by Roberto Boccadoro

Domino Back/Restore is a flexible framework for native Domino backup. The dominobackup.nsf plays an important role for backup and restore operation. It contains the following type of content. Backup/restore/prune configuration Inventory documents for restore operations Restore requests Backup logs You could run backup with different excludes defined on command-line. Or just backup selected databases or incremental backups. But there cannot be different active configurations nor different backup retention in one dominobackup.nsf

Easy to use container image providing ICAP support for ClamAV for Domino CScan  

By Daniel Nashed | 2/22/24 1:11 AM | Infrastructure - Notes / Domino | Added by Roberto Boccadoro

My friend and fellow Ambassador Roberto Boccadoro submitted an Engage session about Domino CScan with ICAP. Sadly his session did not make it into the agenda. But he is part of two OpenNTF sessions. This session idea lead to a new OpenSource project I initiated to help with ICAP support. Thanks Roberto for pushing me to get this implemented! :-) The new project provides a simple to build container image, which natively offers ICAP services over TLS with a ClamAV container in the back-end. The container is ready to be consumed with Domino CScan/ICAP ( It comes with a docker-compose file which glues the official ClamAV container with this new image.

Running Domino in LXC containers on Proxmox requires a trick  

By Daniel Nashed | 2/22/24 1:10 AM | Infrastructure - Notes / Domino | Added by Roberto Boccadoro

Now that VMware might not be everyone's darling any more because of it's new mother ship, I took another look at Proxmox. I know them for quite a while and they are doing a great job. I rebuilt a Intel NUC with 2 TB NVMe disk with the current version of Proxmox. Proxmox supports full VMs and also LXC -- which is an interesting option for testing in lab environments. You can setup a new Linux test machine in minutes from a template. And there are ready to use templates for all major Linux distributions. I had a post long time ago about Proxmox automation on command-line.

XPages JEE 2.15.0 and Plans for JEE 10 and 11  

By Jesse Gallagher | 2/22/24 1:09 AM | Development - Notes / Domino | Added by Roberto Boccadoro

Today, I released version 2.15.0 of the XPages Jakarta EE project. As is often the case lately, this version contains bug fixes but also a few notable features: You can now specify Servlets in WEB-INF/web.xml (as opposed to just via the @WebServlet annotation. This is helpful for defining a Servlet when the actual implementation is in a JAR or when following non-annotation-based examples You can now specify context-param values in WEB-INF/web.xml in the NSF and META-INF/web-fragment.xml in JAR design elements, which will be available to JSP, JSF, JAX-RS, @WebServlet-annotated Servlets, and web.xml-defined Servlets Added @BooleanStorage annotation for NoSQL entities to define how boolean values are converted to note items Added CRUD operations for calendar events to NoSQL, around a few new methods on Repository. This exposes some of the capabilities of NotesCalendar and can be used for, for example, providing an iCalendar feed based on a mail database. To go with that, XPages JEE also re-exports iCal4J as included in the Domino stack for NSF use, though this API is... not smooth The first two here are focused around bringing NSFs more in line with "normal" Jakarta EE applications, while the latter are some nice improvements for the NoSQL driver. I hope to put the last one in particular to good use - for example, OpenNTF's site will be able to provide a calendar of webinars and other events that we can manage internally using a normal Notes calendar, and that sounds nice to me.

Certificate ASN.1 Decoding online  

By Daniel Nashed | 2/15/24 2:35 AM | Infrastructure - Notes / Domino | Added by Roberto Boccadoro

Now that I posted the TLS 1.2 interactive information side today, some of you might also want to get details out of certificates. Certificates are usually public information. So it should be OK to paste them into the website But there is a GitHub project referenced and you could run it also locally. The inner guts of certificates are presented in ASN.1. When you ever has looked at OpenSSL C code, you will recognize the structures.

Domino Backup customized and centralized logging  

By Daniel Nashed | 2/12/24 2:25 AM | Infrastructure - Notes / Domino | Added by Roberto Boccadoro

This question came up last week in a business partner workshop. The partner wanted to centralize the logging of all Domino backup instances. dominobackup.nsf intended per server. You could configure a global configuration database and local instances for the backup inventory. In theory it could be one database for multiple could be also replicated in smaller environments. This would not be recommended. But there is an easier way for a centralized overview of all your Domino backups.

Domino adding Trusted Roots for Java applications  

By Daniel Nashed | 2/12/24 2:24 AM | Infrastructure - Notes / Domino | Added by Roberto Boccadoro

Domino has different places to store trusted roots depending on the part of the application. Beginning with Domino 12.0.2 HCL started to consolidate root certificates into the new domain wide certstore.nsf. But it will take some time to have all parts of Domino to use the new trusted roots back-end. New callers like OIDC or CScan/ICAP and the certificate URL heath check already use the new back-end including UI integration. JVM trusted roots cacerts overwritten by Domino update Java still uses it's own cacerts file, which is part of the JVM directory. The file is only admin/root writable. Domino release installers replace the cacerts file with the latest cacerts available. But this overwrites custom certificates imported into cacarts. This is a common problem I ran into twice in the last two weeks.

Enable DKIM for Domino

New default Let’s Encrypt certificate chain with ISRG Root X1 root  

By Daniel Nashed | 2/12/24 2:18 AM | Infrastructure - Notes / Domino | Added by Roberto Boccadoro

Let's Encrypt finally changed their default root certificate from DST Root CA X3 to ISRG Root X1. The old root expired already 2 1/2 years ago, but was cross signed with the new chain. Now finally Let's Encrypt uses the new root by default, which results in a shorter chain. They have been using the older, longer chain to specially support older Android devices, which didn't have the X1 root in their trust store. When you are using Let's Encrypt ACME and did not specify an alternate chain, there is nothing to change. The new shorter certificate chain will be automatically used the next time the certificate is renewed. But in case you set specific settings, you might now have to remove those settings, because they flipped the certificate chains. The alternate chain is now the older longer certificate chain. For Domino CertMgr the custom setting is "ACME Alternate Chain Suffix".

The Art of Troubleshooting   

By Daniel Nashed | 1/15/24 3:38 AM | Infrastructure - Notes / Domino | Added by Roberto Boccadoro

In all the years I am involved in troubleshooting, I still see the same patterns. I am planning to start a new initiative this year. To start with, I wrote a short abstract end of the year when looking into this. See this as a beginning of a change from my side to better help on community level and also provide better services as a HCL business partner. It will also include troubleshooting steps for different kind of problem types like crashes, hangs, memory leaks, performance problems. Not all of it can be described in howto material. But raising the awareness on all parts of the support process, can significantly help to solve problems faster. I am in the troubleshooting business for over 25 years, read NSD before breakfast and wrote my own troubleshooting tools.

Installing wireguard on CentOS Stream 9

As I do a lot of my research on new Domino versions, Connections versions and HCL DX on my own server at home and as I’m often not at home, I figured I needed a VPN tunnel to my server, so I can work as if I am home. Wireguard has become kind of the de facto standard for these kind of situations, so I looked into installing it on my CentOS Stream 9 host.

Important to know about Domino 14 Inbound Mail Disclaimer  

By Daniel Nashed | 1/12/24 2:40 AM | Infrastructure - Notes / Domino | Added by Roberto Boccadoro

A partner ask in OpenNTF channel about an issue with the new inbound mail disclaimer in Domino 14. It turned out I was able to reproduce the problem on one of my lab servers and this is critical to know if you enable disclaimers written into the body. There are two different ways to setup the feature. 1. Tag the subject line 2. Write HTML to the body of the message with fall back to subject for signed or encrypted messages. My personal recommendation is always to tag the subject, because modification of the body can lead to all kind of side effects with add-on software and also issues that could happen with incorrect formatted messages.

Running Traveler 14 on Windows 11 for testing  

By Daniel Nashed | 1/8/24 3:57 AM | Infrastructure - Notes / Domino | Added by Roberto Boccadoro

The Windows desktop versions are completely untested and unsupported for all Domino related products. It is not recommended to run any Domino software in production on Windows desktop! There are still a couple of scenarios where Windows desktop can be relevant. For example a local notebook installation, a training environment or the Windows Sandbox -- which is also a Windows desktop environment. Domino 14.0 changed the installer to prompt to confirm the unsupported Windows version. But the installer continues to work with Windows 11 after you confirmed the message. As a German partner discovered last week, Traveler 14.0 doesn't install on Windows 11. InstallAnywhere runs into an error: Windows DLL failed to load during Installation. Windows 10 works unchanged. The issue starts with Windows 11.

Open Sourcing Domino Templates - Part 1

HCL just open sourced a number of Domino templates! This initiative of HCL was announced by Richard Jefts to support a more open and vibrant developer community. Main purpose is to allow developers and partners to extend, modify and tweak the product templates, reuse parts of the code in own solutions and allowing those modified versions to be redistributed. Now with the the Apache 2.0 license this will be possible. Also it is now possible to update these templates outside of product releases in a more consistent way if necessary.

Automatically Updating Ubuntu Linux including mail notification

This was on my list for a while. I looked into it, but the mail part wasn't what I wanted. Most admins will just install BSD mailx. But this had way too much dependencies for me. I just wrote a simple tool to replace mailx -> But you could just continue to use the standard package. It wasn't just an option for me, because I try to not install other mail server components on a Domino server (like sendmail). The setup for automatic updates are pretty easy and base on scripting.

How to send mails native on Linux and MacOS from command-line  

By Daniel Nashed | 1/8/24 3:49 AM | Infrastructure - Notes / Domino | Added by Roberto Boccadoro

End of last year SMTP Smuggling was a hot topic. It turned out Domino is behaving well as you can read in Thomas Hampel's blog post who is also linking an interesting presentation about this topic. (See details here --> Because I didn't find any good tool to craft emails required to check, I wrote a simple command-line tool in C. I used the OpenSSL versions of the network communication to abstract the calls from the standard socket operations. It's a nice show case how SMTP works under the covers -- which didn't change for centuries and works the original standards (RFC 821 and 822) are still what is behind all SMTP traffic. Once that worked, I thought adding STARTTLS would be a good addition. After I was done with my smuggling tests and I could sleep well again, I started thinking about to make it a more useful tool. So I added attachment support creating a MIME message with a Base64 encoded attachment. Here is a link to the proejct in my tools repository -->

Is HCL Notes / Domino affected by SMTP smuggling?  

By Thomas Hampel | 1/4/24 1:54 AM | Infrastructure - Notes / Domino | Added by Oliver Busse

SMTP Smuggling is a newly discovered attack to a number of mail server products and mail hosting providers. All mail transfer are based on the SMTP protocol that exists for years where server and client, or two servers talk to each other as defined in an internet standard (RFC 5321) Even with perfect antispam checking, SPF, DKIM, DMARC, etc in place, the vulnerability would allow sending spoofed emails, which can result in a huge problem.
