I should clarify that I am also applying a .P12 wireless certificate to the WT6000 through StageNow successfully. The wireless cert is one of the very first configuration steps in my staging process and the Keystore is initialized through StageNow before it is applied. This at least indicates that the WT6000s can process certificates of some kind through StageNow. Because a .P12 wireless cert works, I tried using the Avalanche .p12 cert and key rather than the ca.pem file and StageNow fails because of some issue with either the PKS/P12 format being incorrect or the password being wrong. I know the password is correct because I've rebuilt the cert twice now with two separate passwords to confirm that and the password works when I import the certificate manually through the Trusted Credential Storage in the Settings->Security menu.
So my current status is:
- Wireless .p12 cert - successfully applied via StageNow MX 5.2 profile
- Avalanche ca.pem cert - successfully deployed and applied via StageNow MX 5.2 profile
- Wireless .p12 cert - successfully applied via same StageNow MX 5.2 profile
- Avalanche ca.pem cert - successfully deployed but NOT applied via same StageNow MX 5.2 profile
I tried a PEM certificate install on the WT6000 using the attached SN barcodes (which have the PEM file embedded in the barcodes) and saw the same issue i.e. the StageNow client does not report any error but the certificate is not installed or listed as a User cert when viewed from Settings/Security/Trusted Credentials). The same profile works on the TC8000 and other Zebra Android devices so I think you will need to raise a support ticket to get this issue fixed on the WT6000 specifically.
