Use a chained SSL cert instead of root CA cert?

We have a PKI infrastructure in place, and I was wondering if I could use the cert and key from one of our issuing CA's which chains back to our root CA, instead of the root CA's cert to do HTTPS proxy?
or more technically, will the WSA take an intermediate cert to use for HTTPS Proxy?
Ken

The only thing to watch out for is that on some of the older versions, I don't recall specifically which - but it's pretty old, the WSA doesn't send the root (intermediate in this case) along with server cert, so it can cause trust issues in your clients that don't already have the intermediate in their trust store.
You should be fine on any 6.3.5+ / 7.0+ version.

Dreaded "must be configured to use a valid SSL cert" - 2008 R2

Hello everybody,
I've been browsing through hundreds of topics on the dreaded "The RD Gateway server must be configured to use
a valid SSL certificate" error using BPA (Windows Server 2008 R2 Std), but still haven't found a proper solution.
Here's the issue: RDGW not operating properly and sometime accepting connections, sometimes not.
I have an external domain example.com and internally, the domain is example.local. I have one server serving Exchange and RD, this is the server responding to mail.example.com and I have an StartSSL issued cert for mail.example.com, which is properly configured
on the server (OWA is working properly with autodiscover etc.). SSL bindings seem alright, default site is using the mail.example.com SSL cert.
If I open the RDGW Manager and go to the SSL Certificate tab, the system looks happy by having the cert installed, everything looks fine. Sometimes I even manage to connect - connection is successful, I can normally connect to any of the servers or computers.
On a second attempt, I just get the message, that the logon attempt had failed. If I run BPA on the server, I get the error of not having a proper SSL cert. If I select a self-signed cert, then also the BPA goes through, but then I have problems with connections
since everybody would need this cert to have installed.
From what I read, my problems are related to the issue that the FQDN of my server is servername.example.local and the cert is issued to mail.example.com. How can I make the thing only to talk via the mail.example.com cert? I don't think I can get a cert
that'd also contain a SAN of servername.example.local from the CA.
What can I do?

Hi Andrej,
Thanks for posting in Windows Server Forum.
Here providing you the article for BPA’s configuration logs, where you can check. It also states that certificate are main problem related to this error. Please check certificate which you have bound have FQDN name of gateway server, the certificate is SSL
certificate and it’s a trusted certificate. Also check that certificate which you have importing to RD gateway must be in local computer/personal store. For more information refer below article.
1. Using the Remote Desktop Services BPA to analyze a Remote Desktop Gateway
implementation
2. RDS: The RD Gateway server must be configured to use a valid SSL certificate
In addition, you need to specify the FQDN name of RD gateway under
DefaultTSgateway in IIS setting. Please go through below article for details.

Hope it helps!
Thanks,

Use of Wildcard SSL cert with DRM

DRM needs a URL to be embedded in the protected PDF document(e.g., mysite.mycompany.com). The SSL certificate for the URL must be from a trusted provider (e.g., Verisign). My question is will Adobe Reader accept for DRM a wild card SSL certificate (e.g., *.mycompany.com) from a trusted provider?

Hi,
The Operations Manager agents support two types of authentication method, Kerberos or certificate based authentication. In order to monitor servers and clients located outside the Operations Manager’s native Active Directory domain, you will need to configure
certificate authentication using either an internal Certificate Authority or through a 3rd party Certificate Authority.

Wildcard SSL cert on ASA

Is it possible to use a wildcard SSL cert on an ASA? That is, instead of getting a specific cert with the FQDN of the ASA, we would use the wildcard cert issued?

Absolutely, it's especially needed in ASA vpn load balancing environments. When you connect to a FQDN that translates to a load balancing IP, one of the ASAs will do an http redirect to its individual hostname, your browser (or AnyConnect) will attempt that connection and ASA needs to have a certificate for that specific hostname. Having a wildcard cert on all ASAs resolves this. I've got this running on several customers.
If you need help with configuration, let me know.
You can either generate private keys on the ASA (and later export it to another ASA or other non-cisco devices), or you could import an existing wildcard certificate with the private keys (in PKCS12-BASE64 format)

Roman

Remote Desktop Services Single SSL Cert with multiple hosts

I am trying to use a single SSL Cert from a third party issuer. I have 3 servers in my deployement all are 2012R2. One contains the RD Web Access role, RD Gateway role, RD Licensing role, and RD Connection Broker role. The other 2 are
RD Session Hosts. I have the SSL cert for the server that has the Gateway and other roles. My deployement is primarily focused on deploying RemoteApp to Windows 8 Thin clients with GPO through the default URL. It works currently with the
exception that the user gets a certificate mismatch error because it is seeing the cert for the gateway server but is connecting to the host servers so the names don't match. Is anyone else using a similar setup and had success with it? I am trying
to avoid buying an expensive wildcard cert to cover all of them.

Hi,
Please verify that the .rdp file embedded in the RDWeb IE page matches the same one from RADC. To do this, log on to RD Web Access using IE, right-click and choose View Source. Find the goRDP function for the icon you want to examine and copy
the text between the ' marks. Next paste this into the escape text box the below page:
http://www.web-code.org/coding-tools/javascript-escape-unescape-converter-tool.html
Click complete unescape to get the plain text version. After that you can select all of the text in the clear text box, paste it into a blank Notepad window, then save as a .rdp file. Once you have the .rdp file created you can compare
it to the other ones and see if any of the names are different, see if it gets the certificate error as well when you double-click it, etc.
Do you have any proxy or other non-default network configuration on your Windows 8 embedded clients?
Thanks.

Wildcard SSL Cert on ASA 5500

What do I need to do on the ASA 5520 to be able to use a wildcard SSL cert? I'm running 8.2.5 code.

Make sure you get the cert in pkcs12 format and no fqdn. Other than that, just follow the config guide.

GoDaddy SSL Cert Signed by Unknown Authority

At my school we have one Apple server which we recently upgraded to 10.5. We're using it to run a blog for teachers. We switched the site to use SSL and purchased a GoDaddy SSL cert (the wildcard type). The common name on the certificate I created in Server Admin is for *.e-lcds.org, this is the same common name I gave to GoDaddy in the CSR.
I received both the certificate and the intermediate certificate from GoDaddy and installed both. Server Admin now says that the site is signed correctly by GoDaddy. The intermediate certificate (looking at Keychain Access) is not signed correctly though according to the server. The error is "This certificate was signed by an unknown authority"
In the process of originally trying to figure out SSL certs I deleted all of the GoDaddy ones which I (thought) had added to start with a new one and have it re-keyed (which worked). I unfortunately may have deleted whatever certs need to be installed to verify the intermediate cert from GoDaddy. Is there a way to re-add these? Or is this another issue altogether?
Thanks in advance,
-MRCUR

I ended up wiping the server since we switched it's roles with a Linux box. I'm now using the GoDaddy SSL cert on the Linux box and the XServe.

SSL Cert used to sign Jars for distribution via WebStart

Hi,
I have an SSL cert (Comodo InstallSSL) for my website and wondered if I can use it to sign jars so, when distributed via webstart, the old "untrusted source" message doesn't get displayed. I've been doing a lot of reading but, to be honest, I can't really find my bearings! I have imported the cert into my keystore but get the message when I try to sign a jar:
Certificate chain not found for: myalias myalias must reference a valid KeyStore key entry containing a private key and corresponding public key certificate chain.I have the following files in relation to my cert:
xxx.cabundle (this can be imported into keytool easily)
cert/xxx.crt (looks like a PGP file, cannot be imported (-import) into keytool)
private/xxx.key
My questions I suppose are:
1. Can I use a cert issued for SSL to sign jars for webstart distribution?
2. If yes to 1; what steps other than importing the cert alone (which generates the message above) do I need to do to achieve this?
Any help would be appreciated!
Rich

Hi,
yes, the pkcs12 certificate includes the private key, as opposed to pb7 which does not.

Using internal SSL Certs for Webview and Reskill (ICM 7.2.X)

Hi,
I would like to use corporate ssl certs for webview and reskill to avoid the user having to install the self signed certificate on the local machine. Has anyone any experience of this? Can it cause any unforseen problems?
My plan for webview is to create the certificate request in IIS for the default website, use this csr to generate the cert, then complete it by uploading the certificate.
For reskilling, I will assume I will have to do some command line stuff here ...
eg: keytool -genkey -keyalg RSA -keystore hostname.key
to create the key,
keytool -certreq -keyalg RSA -keystore hostname.key -file hostname.csr
to create the csr, and
keytool -import -trustcacerts -alias tomcat -file hostname.cer -keystore hostname.key
to import the new cert
Suggestions or comments for anyone who has tried this before would be appreciated.
Regards,
Brian

I've never done it on a version so old, but at the end of the day it's just IIS and Tomcat and importing an SSL cert is very standard.

Use Wildcard SSL Cert to Monitor Non-Domain COmputers

Can SSL cert be used in Mail Services?

Hello,
Can I use SSL server cert for Apache in Mail services, or must I use S/MIME certs? Anything that I must be aware when buying the S/MIME cert for 10.6 Mail Services?
Thanks alot!

Thanks very much!!!
Do you know which port(s) external mail client will use to get the cert from the Mail Server during handshake? My preliminary testing shows the mail client gets the cert via 443, and therefore it is getting another cert from my supposedly web server!
My set up in brief :
Airport Extreme acts as the gateway, load distributed by port no. to multiple servers, each handling a different service, and each has a different internal IP address. The external DNS service provided by DynDNS has 2 CNAME entries (one is www.servername.com, another is mail.servername.com) both pointing to the same fixed IP address.

DPS Server SSL Certs Added to CA Certs Instead of Server Certs

When adding a replacement SSL cert to our Directory Proxy servers via either command line or DSCC, the server cert added is listed under "CA certs" (dpadm list-certs -C /var/dps), instead of "Certificates"/server certs (dpadm list-certs /var/dps) where it should appear.
I have read this similar thread:
SSL Cert Added to CA Certs Instead of Server Certs
...which doesn't appear to be resolved
I have displayed the cert and found the following details for this cert: (noting the question in response to the above mentioned thread)
X509v3 Basic Constraints: critical
CA:FALSE
Any ideas?
Gracias

What is odd is that this certificate worked fine on every other instance except this one. I will check the details of the certificate.

How to get OS X to accept an SSL Cert the way other UNIX clients do?

I'm hoping some of the network gurus can suggest a solution for me. My current config is 10.5.4 on PPC.
I have a host that I need to connect to using SSL but their certificate has a host name mismatch (they are a small org, and can't afford another SSL cert for the moment). I know the cert is valid, so I'm not worried about the security implications of using it.
On other *NIX clients, I simply have to add the cert into the root chain (e.g. /etc/ssl/certs/ca-certificates.crt), restart the application, and all apps will then accept it as valid.
On OS X, I've imported the cert into Keychain Access, marked it as "Always Trusted" and set up a policy to "alias" it to the URL I need to access with my application (not a web browser) (ref: KB article: HT1679) in both the login and the System keychains, yet the client application still errors out and refuses to connect to the URL.
How can I configure client SSL on OS X to work like other UNIX configurations? There doesn't seem to be a way to override the extremely restricted behavior.
I have MacPorts installed and am open to an application specific "hack" if necessary, ala "LDLIBRARYPATH", if anyone thinks that's feasible (which is what I am looking at now). Conceivably I could recompile the client application since it's OSS, though I'd rather avoid that if possible.
Any suggestions would be appreciated.
Thanks in advance--
=N=

when you connect with a web browser to an https site that has a mistmatched cert it warns you and you have to tell the browser to ignore the security issue to let you carry on.
what unix apps are you using to connect to this server?

SSL cert on ASA 5512 from Thwate or Digitcert

I ran into the issue when I install SSL123 cert from Thwate . I did not have issue with SSL cert from DIgitcert- their process and steps are simple and using better encryoption - SHA256. Compare to Thwate - their support did not let me use SHA2 and I had to use SHA1 - according to some organisation SHA1 will be retired soon
Let me explain how to install SSL123 from Thwate into ASA 5510- you can follow their instruction - but generate CSR with 2048 - with 4096 did not work .Once you apply into their portal use SHA1 ( SHA2 did not work ) . Before you get email with their CA - install Root and Secondary intermidiate certificate - located in their website . After you get email with the new cert - you can install under Idendity certificates where still says pending .Note - there are CSR checker tools - before you apply it into CA _ google CSR checker - make sure your CSR does not have any errors
Note - When you install each certificate - trustpoint association could be in different order - example - ASDM_trustpoint0 , ASDM_trustpoint1 , ASDM_trustpoint2 etc . If you use the same ASDM_trustpoint0 for all certs- root , intermidiate and signed certificate - Did not work and you are getting ERROR - :Failed to parse or verify imported certificate
here is the link you can follow - https://search.thawte.com/support/ssl-digital-certificates/index?page=content&id=SO16141&actp=search&viewlocale=en_US&searchid=1429125296765
Finally you can check your SSL cert - google SSL checker to see if your chain as good all the way and what need to be fixed

First of all, you don't need the server names in the cert if your Exchange urls are configured to a load balanced url. Going forward, you will not be able to get a certificate from 3rd party with internal urls (server fqdn) in it.
When you export the certificate from CAS1, make sure that you include the private key as well (there will be a check box to tick) and import it back on CAS2.
If not, you can just import the certificate into CAS2 by selecting Import Exchange certificate in EMC and select the 3rd party cert (just like you imported on CAS1).
Yes, you need the certificate on both servers, otherwise you will get certificate errors on clients (assuming that there is some form of load balancing in place - NLB or hardware).

IMAP Mail Setup with self-signed SSL certs

I am unable to set up IMAP access to an email account of mine on the new iPhone mail app. The setup stalls at "verifying" and I can't seem to save the info entered and then disable SSL in the advanced setup.
Also, it doesn't seem possible to install SSL certs out of safari. On the computer I was able to navigate to the server via https and permanently accept the SSL cert. The option doenst exisit in Safari Mobile. If you have the servers cert (.der) file in the web root of the server, possible to download and install the certificate. This solved a similar problem for my ExchangeMail push with our Kerio server. Unfortunately, the certificate file of that other IMAP account is unavailable..

If possible, instead of configuring it on the iPhone, try configuring it on your computer and using iTunes to sync the configuration itself to the iPhone. I am connecting fine to an IMAP server with a self-signed certificate. The first time I opened Mail (on the iPhone) it prompted me with a dialog saying the certificate was invalid but I was able to accept it. Since then, it has never prompted me again about validity of the certificate (even after rebooting the phone) so I believe the Mail program can permanently accept a self-signed certificate.
And yes, there doesn't seem to be a way for Safari Mobile to permanently accept self-signed certificates. I have read that the iPhone is supposed to pull certificates from the Keychain but this does not appear to be the case.
