APNS IIS Chaining Error
If your experiencing a chaining error when completing your APNS cert response in IIS then please navigate to http://www.apple.com/certificateauthority/ and download the Apple Root Certificate + CRL and the Apple Integration Certificate + CRL and install these appropriately into trusted root ca authority, intermediate stores of the IIS server that you are intended to complete the APNS certificate response on.

You can register/create an Apple ID at – http://appleid.apple.com/cgi-bin/WebObjects/MyAppleId.woa/wa/createAppleId?localang=en_US and the APNS portal is available at – http://identity.apple.com/ to submit your signed APNS CSR to be signed.

0: I would recommend downloading and reading through the current Citrix Reference Architecture for XenMobile 8.6 at –
1: Review the system requirements –
http://support.citrix.com/proddocs/topic/xenmobile-prepare/xmob-deploy-device-manager-sys-reqs-con.html and remember to consider if you are ever going to intend managing your mobile, smart devices inside and outside of your organisations trusted network. I use split DNS so the same FQDN is accessible both in/outside of my demo environment. I FQDN is typically best over a IP addr as you can always adjust the underlying IP Address of the XDM FQDN in DNS (Internal and Externally) to move it (a) from one subnet to another with different IP addressing (b) from ISP to ISP (You will always get a new allocated IP range as ISP are allocated IPv4, IPv6 address blocks) without having to reinstall the XDM. Your probably asking your why would I need to reinstall the XDM? When you install the XDM you will also configure a CA as the XDM will push certs to the devices being enrolled to restrict the devices capabilities based upon the MDM policies that you have applied within the XDM web UI so if the IP addr changes you need to reinstall and re-enrol every device so using a FQDN means that your adjust your DNS records both internally and externally with the new IP addr for your FQDN and there is no need to reinstall the XDM as the FQDN has not changed and devices will still be managed.
2: Network TCP Ports Source vs. Destination – http://support.citrix.com/proddocs/topic/xenmobile-prepare/xmob-deploy-component-port-reqs-n-con.html.
3: Generate an APNS certificate or use your existing APNS certificate – http://support.citrix.com/proddocs/topic/xenmobile-connect-users/xmob-dm-config-requesting-apns-con.html. If you have any chaining error(s) please refer to the APNS process in the beginning of this WordPress blog article/entry.
4: Download and install the latest STABLE versions of the Oracle Java JDK and JCE files at – http://www.oracle.com/technetwork/java/javase/downloads/index.html. You should never use BETA or builds known to be unstable or insecure. Remember to extract and copy the *.jar files to the following paths – once the Java JDK has been installed on the XDM 8.6 server.
5: Liaise with networking team(s) to ensure that your internal and external firewalls ACL are correctly configured for your XDM deployment. Take a look at the Architecture Diagram – http://www.citrix.com/content/dam/citrix/en_us/images/info-graphics/xenmobile_architecture_86.png and the read through the latest Reference Architecture documentation for XM8.6 – http://www.citrix.com/content/dam/citrix/en_us/documents/products-solutions/citrix-reference-architecture-for-xenmobile-86.pdf.
6: I would once again recommended downloading and reading through the Deploying the XenMobile Solution ( Currently based off 8.5 at the time of writing this blog entry) – http://support.citrix.com/article/CTX139235, alternatively continue.
7: Navigate to this eDoc’s link to begin the installation of the XDM 8.6 – http://support.citrix.com/proddocs/topic/xmob-install-dm-86/xmob-deploy-device-manager-install-steps-tsk.html

Creating A Valid Chained Certificate For Your XDM’s FQDN
There are various different methods for achieving or generating a *.pfx12 certificate you can always choose to disagree with my approach and use your own method(s) and or approach(s).

Microsoft Enterprise CA ( WaRniNg – (DRAFT & MAY CONTAIN ERROR(S)) )
1: Create a CSR for your XDM FQDN on your Enterprise CA or another server that is domain joined and has the Enterprise CA root certificate installed and valid. Please also be sure to ensure your select 2048Bit encryption when competing the wizard and save the CSR request to your desktop for convenience.
2: Open up the text document to retrieve CSR code by selecting all and copying.
3: Navigate to your Microsoft Enterprise CA CSR signing website e.g http://FQDN/certsrv
4: Request a certificate
5: Click Or, submit an advanced certificate request
6: Click Submit a certificate request by using a base-64-encoded CMC or PKCS #10 file, or submit a renewal request by using a base-64-encoded PKCS #7 file
7: Enter in the CSR generated code from the XAC or XDM into the Saved Request input box then change the “Certificate Template” to Web Server
8: Click Submit
9: Download the certificate response in Base 64 format and save as certname-base64.* and then prior to closing the web page save the cert in DER format if required in the following format certname-DER.*. Tip download the *.p7b formats for each aswell. NOTE: Upon completion of importing and activating your cert on the XDM server(s) you should delete any unsecured or unused XDM certs on your file servers and desktop for security purposes.
10: Now complete the SSL signing request certificate in IIS on the Enterprise CA using the Base64 format signed SSL certificate and then export the cert and enter in a strong password and please do not forget the password. Save the exported cert on your desktop and copy onto a file share or to your file server and then copy the *.pfx12 cert you’ve just generated on your XDM’s desktop for simplicity as the next steps will require you to edit two files in notepad and create directory to put the the SSL certificate in.
10: Follow the steps in the following CTX article at – http://support.citrix.com/article/CTX136952 or http://support.citrix.com/proddocs/topic/xmob-dm-8/xmob-dm-manage-securityid-configcert-ssl-tsk.html to apply your Enterprise CA signed *.pfx12 SSL certificate to your XDM’s FQDN.

1: You will require a clean, fresh installation of XDM without any devices enrolled as I have not tested this process POST devices being enrolled.
2: Download OpenSSL for Windows at – http://www.openssl.org/related/binaries.html, alternatively if the link is dead or moved locate the download at – http://www.openssl.org/.
3: Install OpenSSL by following the onscreen instructions and remember to check the pre-requites prior to installation of OpenSSL.
4: Now that you have installed OpenSSL following the steps in this Citrix blog article at – http://blogs.citrix.com/2013/11/05/creating-a-private-key-and-csr-for-xdm/.

Deploying and Load Balancing a XDM cluster
1: These two videos available on the Citrix Blog available at – http://blogs.citrix.com/2014/03/05/configuring-xenmobile-device-manager-ha-clustering-in-less-than-15-minutes-part-1/, http://blogs.citrix.com/2014/03/05/configuring-xenmobile-device-manager-ha-clustering-in-less-than-15-minutes-part-2/ that show you how to implement a XDM cluster for high availability referenced from the following eDocs node – http://support.citrix.com/proddocs/topic/xmob-dm-config-86/xmob-dm-manage-ha-wrapper-con.html.
2: Once your NetScaler (Gateway) has been deployed and the initial configuration completed and the appropriate NS(G) licenses uploaded then please watch this video on Citrix TV – http://www.citrix.com/tv/#videos/9294 which shows you how-to L/B the XDM using the XenMobile wizard in the NS(G).
