XenApp / XenDesktop, Android 4.0 and Certificates

I’ve encountered various certificate related issues with Citrix Receiver on mobile devices over the years, and most of the time the issues related to incorrectly installed or configured certificates.  Some of the common issues are the intermediate or root certificates aren’t installed, or the certificates aren’t linked correctly.

However Android 4.0 however seems to be fussier about certificates, and I’ve had working setups with Android 2.3 stop working under Android 4.0 (while Windows/Mac/iOS etc work all along).  To help assist those thinking about a new certificate, here are a couple of certificates that I have found to work 100% reliably with Android as well as some I know that seem to have issues:

Working Certificates:
GeoTrust TrueBusinessID http://www.geotrust.com/ssl/ssl-certificates/
GeoTrust TrueBusinessID Wildcard http://www.geotrust.com/ssl/wildcard-ssl-certificates/
GoDaddy Standard or Premium SSL http://www.godaddy.com/ssl

Certificates I have had trouble with:
RapidSSL http://www.rapidssl.com/
Digicert http://www.digicert.com/

There will be more certificates out there that work reliably, but I have not tried them – once I discovered the GeoTrust ones work reliably I’ve stuck with them.  If you have reliable experiences with other certs, feel free to post a comment so we can all benefit from each other’s experiences.
