Work with CA certificates
If a certificate authority (CA) certificate gets compromised, or for
some other reason your organization doesn’t want to trust it, you
can disable or remove it. To do so, follow these steps:
1. Touch Settings > Personal > Security > Credential stor-
age >Trusted credentials. The trusted credentials screen has
two tabs:
System displays certificate authority (CA) certificates that are
permanently installed in the RoM of your tablet.
User displays any CA certificates that you have installed your-
self, for example in the process of installing a client certificate.
2. To examine the details of CA certificate, touch its name.
A scrolling screen displays the details.
3. To remove or disable a CA certificate, scroll down to the bot-
tom of the details screen and touch either Disable for system
certificates or remove for user certificates.
When you disable a system CA certificate, the button at the
bottom of its details screen changes to Enable, so you can
enable the certificate again if necessary. When you remove a
user-installed CA certificate, it is gone permanently and must
be re-installed if you want it back.
4. In the confirmation dialog that appears, click oK.
