TA is working with a customer and asked the questions below regarding the certificate store for Android.
Can anyone provide any feedback? Thanks.
 
Secure Certificates
If the VPN or Wi-Fi networks rely on secure certificates, obtain the certificates and store them in the ET1’s
secure credential storage, before configuring access to the VPN or Wi-Fi networks.
If downloading the certificates from a web site, set a password for the credential storage.
ET1 supports X.509 certificates saved in PKCS#12 key store files with a .p12 extension (if key store has a .pfx
or other extension, change to .p12).
The ET1 also installs any accompanying private key or certificate authority certificates contained in the key store.

The certificate that I am installing is save in a “.cer” format. The customer believes the following
So here is the email the customer sent. The application is from Ascom not custom made just the normal distribution.
I also downloaded the cert directly from the web site. Imported thru the control panel. To user certs. On 4.1.1 looks like they have blocked access to root certs. Load to a Samsung TAB 3 and it worked ok.
