I need to set up SSL over Active Directory. I googled a lot but could not found a decent write up about how to do this. Please if you know some good resources about this let me know.
Thanks!
Sounds easy - but I ran into quite a few problems getting trusted connections with SSL working in our environment. The article was about ADAM but is just as applicable for AD. In our environment I couldn't install domain-related services like cert-server, nor act as domain-admin.
I blogged about how I got this working a while back
http://stephbu.wordpress.com/2006/11/29/using-adam-with-asp-net-2-0-activedirectorymembershipprovider/
Dan and Erlend's postings were invaluable.
Took some backflips to get it done.
The Lightweight Directory Access Protocol (LDAP) is used to read from and write to Active Directory. By default, LDAP traffic is transmitted unsecured. You can make LDAP traffic confidential and secure by using Secure Sockets Layer (SSL) / Transport Layer Security (TLS) technology. You can enable LDAP over SSL (LDAPS) by installing a properly formatted certificate from either a Microsoft certification authority (CA) or a non-Microsoft CA according to the guidelines in this article.
http://support.microsoft.com/kb/321051
Can you be more specific. What is the client trying to do? Active directory support ldap over ssl by default. There is nothing that should be done to activate it. It is done in port 636/tcp. http://technet.microsoft.com/en-us/library/bb727063.aspx
The absolute fastest way to install SSL into AD is to load MS certificate services. Once this is installed, all domain controllers will request a new certificate automatically and update themselves...

I would like to set some SSL certificates for one app I have on heroku (a simple application based on nodeJS + Vue).
I know if I upgrade to the Hobby Plan (7$ for month) I can have it automatically.
But for now it would too much money for a test application, so I am wondering if I can achieve some similar goal also with a Free Plan.
so:
Is it possible to set SSL certificate for an app on Heroku JUST with the Free Plan?
Maybe in a complicated/tricky way via CLI?
From the Heroku pages and documentation it looks not possible.
But I have to ask :)
Here I have a better approach to deal with this. As Heroku Doesn't provide SSL for Free Plan.
But You can use Cloudflare which gives free SSL.
You can Use Cloudflare As Bridge For SSL.
Requirement:
Cloudflare Account
Your Application should not have inbuild SSL redirection (like redirect-ssl)
Otherwise, This will result in Too Many Redirect Error
Step 1: Point Your domain to CloudFlare. You basically open an account an enter your domain when prompted. You may be given instructions to change your domain name servers.
Step 2: Add Cname Record of Heroku Server in DNS of Cloudflare. Instructions are here
Here You will get Some SSL Security Issue.
Step 3: Now Change Your SSL/TLS encryption mode to Flexible (Not Full). *Important
Now Understand the Working:-
Client(Browser) Make Request to https://example.com
First, the request reaches the Cloudflare with SSL. (User see encrypted connection to the server.)
Then Cloudflare makes request to Heroku Server(Origin) with Non-SSL (Non-Https and Unencrypted).
Then Heroku Server (Origin) returns the Response with Non-SSL to Cloudflare.
At the end Cloudflare forward the request to Client (Browser.)
You might think, What is the benefit of just encrypting half system.
but "Something is better then nothing".
You are here because you don't want to spent money on heroku paid dynos.
This method is better for those who is using http. Atleast it protects the most vulnerable side (client side). Where most of the attack happen. There is very less chances of attack between cloudflare and your server. Because of network reach.
Having less vulnerable probability is better then 100% vulnerable system
I have tested this method and working on https://www.auedbaki.com
Late response but I'm adding here I just spent an hour trying to setup SSL with Heroku - resulting in a dead end.
The bottom line is that Heroku mentions they offer free SSL certificates but that's really not the case unless you have a Hobby ($7/mo) or Pro plan.
This link has more details and feedback from other users facing the same issue.
The answer above about LetsEncrypt is incorrect. Although you can get a free certificate, it cannot be included in a free Heroku app.
Other users have pointed to this article with a step-by-step guide but the guide is outdated and the 'Labs' option mentioned does not work with Heroku anymore.
see comments below for some alternative suggestions
In my specific case, I was able to get a free SSL on zeit.
Here's how you get FULL SSL using Cloudflare for FREE.
Step 1: Point Your domain to CloudFlare. You basically open an account an enter your domain when prompted. You may be given instructions to change your domain name servers.
Step 2: Add Cname Record of Heroku Server in DNS of Cloudflare. Instructions are here. Here You will get Some SSL Security Issue.
Step 3: Now Change Your SSL/TLS encryption mode to Full
Step 4: In your DNS settings, you’ll want to create a CNAME: yourdomain.com -> yourapp.herokuapp.com.
(I learned about the general approach here https://mikecoutermarsh.com/adding-ssl-to-heroku-with-cloudflare/ Although it's old, it still works.
I had this issue also. I wanted to set up a custom domain for my free account on Heroku for my React App. I searched so much info on the web and read loads of documents from Heroku support.
The conclusion is that on the Heroku free account, a custom domain name with SSL certificate cannot be setup. If you need SSL with your custom domain name, you need to upgrade to any of their paid hosting accounts.
Heroku does provide SSL certificate for their free account as long as it is not using a custom domain name. So the standard free account URL will be something like this "https://your-app-name.herokuapp.com"
NB. Google Firebase allows free hosting and Custom Domain name with SSL, for up to a certain amount of traffic before charging. For testing an app, this will be a perfect alternative. I am using it. And it was easy to set up my custom domain.
I hope this saves you hours of searching.
Since you don't make explicit if you need to apply the SSL certificate to a custom domain, I think it's necessary to say that according to the Heroku documentation:
Apps using free dynos can use the *.herokuapp.com certificate if they
need SSL.
https://devcenter.heroku.com/articles/ssl
Maybe future readers could find this answer helpful...
If you are using
1]free heroku,
You can't use 1)free ssl or 2)paid ssl
2]paid heroku
1)you get free ssl 2)you can use paid ssl also
Solution
1]get paid heroku
2]move to netlify or other alternatives
Free SSL in Heroku doesn't exist, or let me just say that it's impossible to achieve it on a free plan.
For you to be able to include any form of third party SSL in Heroku, be it paid SSL or Free Third Party SSL, you have to change to Hobby or Professional dynos for the SSL to work.
An easier option, if you're using Heroku, there's no need to buy a third party SSL. Just change to Hobby or Professional dynos.
For you to be able to change the dyno type, select your app, go to sources section on the upper part, just bellow it, click on the Change Dyno Type button.
Hobby Dyno will cost you $7 a month while Professional Dyno will cost you $25 - $500 a month.
After all that, remember to go to your Rails App:
Go to; .../config/environments/production.rb
--> Uncomment the following line:
# config.force_ssl = true
---> To:
config.force_ssl = true
After that, you'll be able to achieve your SSL but not FREE.
If you don't mind hosting your frontend on another service you can host it in Vercel, with free SSL, while you keep your backend at Heroku. Quite straightforward!
https://vercel.com/
One way around this could be setting up a proxy server on a host you can set SSL certificates on and then simply forward requests to the free herokudns domain using encryption as well.
You'd have to have a separate server with something like nginx or httpd running.. I am not sure of a free service to host the proxy, but usually when you sign up for a domain you may get a hosting addon with it, or perhaps people already have acess to an encrypted host and just want to also use Heroku for their node applications.
Setting up a httpd proxy would look somewhat like this (from https://serverfault.com/questions/84821/apache-proxypass-with-ssl):
<VirtualHost 1.2.3.4:80>
ServerName customdomain.com
SSLProxyEngine On
SSLProxyCheckPeerCN on
SSLProxyCheckPeerExpire on
ProxyPass / https://heroku-app-name.herokuapp.com
ProxyPassReverse / https://heroku-app-name.herokuapp.com
</VirtualHost>
This way you have full encryption all the way :)
This is a question rather than an answer, actually. Has anyone tried ZeroSSL? It offers free SSL, and here is an installation guide for Heroku. However, SSL Endpoint is apparently deprecated and not recommended by Heroku, and it appears to be paid addon of Heroku.
$ cat example.crt ca_bundle.crt certificate.crt
I could not make sense of this line in the help. Perhaps, > is missing? Where does example.crt come from, when I only have the following files?
certificate.crt
ca_bundle.crt
private.key
Or can Heroku SSL accept SSL certificates issued from ZeroSSL?
I am hoping someone can help me out with a frustrating configuration problem I'm having with IBM FileNet Content Manager 5.2.1 (aka P8 5.2.1).
We have an existing system setup that uses Microsoft Active Directory as our LDAP directory service for P8 and that has worked fine to date. That said, we are now wanting our .NET apps to talk to P8 (via the Content Platform Engine .NET API) using WCF instead of legacy (and now deprecated) WSE but we have run into a problem. WCF requires that all communication occur over SSL - on the surface, not a problem. If you want to talk to the IBM Content Platform Engine (CPE) over SSL however, according to IBM's documentation, you must also change the underlying default LDAP connection from unsecured to SSL as well (in the process, changing LDAP to use port 636 instead of 389).
Following both Microsoft's and IBM's docs, I first enabled LDAP over SSL on Active Directory and tested accordingly. Using Microsoft's LDAP utility, ldp.exe, I can successfully connect and bind to Active Directory on port 636 over SSL.
The next step however is where I hit a wall - Enabling SSL for Content Platform Engine. I followed all the steps involving adding the Active Directory Server's CA certificate to the CPE's application server keystore - no problem. The next step in the configuration instructions however asks you to start the Administration Console for CPE (ACCE) and reconfigure the directory configuration properties - telling it to use SSL on port 636 and... KABOOM! When I attempt to save the configuration, the save fails, stating
An unexpected exception occurred. Message was: Failed connecting to ldap://ad1.domain.com:636
Unfortunately, I can't find any additional info as to why it failed to connect - I assumed it was due to something minor, such as a port conflict. To test that theory, I installed Microsoft's LDAP test utility on the CPE server and attempted to connect to the Active Directory Server over SSL on port 636. Much to my surprise, that worked just fine - grrrr...
I am now at something of a loss as to what to look at next. Anybody out there with experience configuring CPE to use SSL in an Active Directory environment?
Thanks in advance for any-and-all assistance.

This is not true. FileNet can work with non-secure LDAP, while at the same time working with WCF.
Now, if you would like to solve why FileNet will not connect to a secure LDAP, then you should start with your WebSphere
Check WebSphere's Keystores to ensure that the AD's key is contained. Follow #M.Tamboli's advice and restart WebSphere.
Also make sure that you check WebSphere's SystemOut.log logs, as you may find more info in there.
I'm not sure if it is necessary, but you may also want to add/change the LDAP config that is setup within WebSphere itself.
We are setting up replication between RavenDB instances running in server mode. The instances are in different availability zones so we need a secure connection between the servers. According this this post SSL is not supported in server mode but
should be easy to add
Is there an extensibility point in the API where SSL support can be plugged in?
The API doesn't have any place for this currently, but I'm sure it would be a welcome contribution if you were so inclined to write this and submit a pull request. The underlying server is just a System.Net.HttpListener, which can be wired for ssl.
Your entry point would be at Raven.Database.Server.HttpServer.StartListening()
You would want the SSL certificate to be as easy to configure as the hostname or port. The cert itself should probably be pulled in from the Windows certificate store.
I would like do use Atomic Transactions between WCF and Weblogic, but I'm facing many problems to configure it.
I've already turned on the Wsat on Windows and associated it a valid certificate. I also enabled the SSL on IIS and configured the https port.
My main doubts are about the right WCF binding configurations and how and where I import the IIS certificate on Weblogic.
I imported my Wsat certificate in Demo.jks file (Weblogic keystore), but it did not work.
Best regards,
ps: Forgive my poor english :)
We're having an issue with securing an intranet / internet website with SSL where
we can't know the qualified domain name in advance.
Basically, I'm trying to make a program that will be installed on a webserver
outside my direct control, to be accessable over intra- or internet. In either case
I want it to be secure via SSL (https). To do this, I would like to include and
install a SSL certificate on the target machine. My installer is fully prepackaged
and should not require any particular during- or postinstall intervention from my
end. Problem is, I can't know ahead of time the target machine's name or domain
name, so as far as I can tell the SSL connection will be returning warnings (or
worse?) when accessed, since the certificate I include will (must) have a different
name on it.
I really want to avoid those warnings, but I still want to keep it secure. Is there
any way to install a SSL connection without certificate warnings without the domain
name known ahead of time?
Thanks for any help you folks can give.
What you want to do is not possible. Here's why.
A certificate will include a set of names (Common Name, possibly along with Subject Alternative Names, possibly including wildcard names).
The client's web browser will do the following:
The user wanted to visit "https://myapp.mydomain.com/blog/posts/1".
The request is via SSL and the domain name in the request is "myapp.mydomain.com".
Get the certificate from the Web server.
Ensure that at least one of the names in the certificate is exactly equal to, or wildcard-matches, the domain name in the request.
Display the page.
Therefore, you need a certificate with the exact domain name (or a wildcard matching the exact domain name) by which the application will be used. And the certificate needs to be available at the same time as, or later than, the time when the exact domain name of the website becomes known, and cannot be made available any earlier.
You seem to be under the misapprehension that somehow a certificate can "create" or "install" an SSL connection. That is false. The Web server - Apache, IIS, Nginx, LigHTTPD, or whichever one you happen to use - is the program that knows how to every aspect of SSL connectivity. The certificate is just a file that the Web server sends to the client, without even opening or using in any way.
Additionally, the author of a webapp to be distributed is not responsible for creating or distributing certificates, and should not be under the misapprehension that he is responsible. Only the website maintainer should be responsible for obtaining a certificate for his website. As another person remarked, in your installation process or perhaps in a post-installation process, you may ask the person installing the webapp for a certificate. But that is the best you can do.
The best you can do is to buy a wildcard SSL certificate - but wait, it's not what you think. You still need to know the second-level domain (the TLD being ".com") ahead of time. You can effectively ask for a cert that covers *.foo.com - then any site, a.foo.com, b.foo.com will be covered. Of course, these certs are more expensive that FQDN certs because you are doing the buggers out of some extra coin.

Each of those sites should have their own SSL certificate. Why not prompt the user to provide the cert file during installation?
In most (if not all) cases, the SSL certificate is associated with the webserver (apache, IIS, etc.) and is not part of your application. It's up to the admin of the web server to install the certificate and not you as the author of the program.
If your installation program does have the ability to modify the web server configuration, and you are willing to have it use a self-signed certificate, you can script the creation of the certificate to allow the domain name to be input. However, I sense this is not really available to you. Also, a self-signed certificate will generally cause certificate warnings.
If I understand you correctly there might be a solution to your problem now. This solution won't help you, however, if you have no control over specifying what SSL certificates are served from the web server where your program is installed (as mentioned by someone else). If your program itself contains a web server you won't have this issue.
If you start with a trusted https website, you can make cross-domain TLS (SSL) XmlHttpRequests to the web servers that are running your application. This is made possible using the opensource Forge project. The project uses a TLS implementation written in JavaScript and a small Flash swf to handle the cross-domain requests. Your program will need to serve an XML Flash policy file that grants the trusted website access to the web server running the application.
Your program will also need to generate a self-signed SSL certificate and upload it to the trusted website. From there, each program's certificate can be included as trusted via the JavaScript TLS implementation. Alternatively, you can have your program upload its certificate to be signed by a CA you create, using a common or subject alternative name that is appropriate for your use (it doesn't have to be the domain name). Then you can use JavaScript to trust the CA certificate and look for the correct name on each certificate.
