Loading a Certificate
If you choose to use transport layer security (TLS) with WPA or
802.1x security, you need to have a unique client certificate on
the CK31 and a trusted root certificate authority (CA)
certificate. You can use a third-party CA to issue unique client
certificates and a root certificate.
There are three ways to load certificates on the CK31:
• If you are using Active Directory to issue certificates, you can
use the Enroll Certificates application to load the certificates.
• If you are using another third-party CA, you can use the
Import Certificates application to load the certificates.
• If you have multiple certificates to install, you can use the
Import Root Certificates and Import User Certificates
functions.
Note: For certificates to be valid, the CK31 must be set to the
correct date and time. After cold booting the CK31, you may
need to correct the date and time.
To load certificates if you are using Active Directory
1 Configure the network and radio settings for the CK31 to
communicate with your certificate authority or establish an
ActiveSync connection with the CA.
2 From Intermec Settings, select Communications > 802.11
Radio > Certificates.
