Endpoint Client Custom Software Signatures Problem

[Rikki]

Hello,

So we're utilising the Harmony solution to download and deploy endpoint packages using inTune/WDAC (Windows Defender Application Control) simply we would like to upload our own custom certificate to Harmony portal to apply to our downloaded packages. 

What we're facing is when trying to upload a certificate (Policy > Export Package > End Point Client) in the Software Signatures. Has anyone actually been able to do this? Because no matter what certificate we've used it hasn't been able to import the certificate. We did also try to deploy the certificates and using SmartConsole connecting to the Harmony management address, but it still fails.

The error doesn't provide any feedback why, furthermore the documentation just suggest a self signed certificate (from our PKI infra), which we've done also TAC have suggested that's all that it needs to be. 

We're already working with our support partner who have a ticket open with TAC but we're making no grounds there, the ticket has been open for almost 6 months and even speaking with the main Dev. 

Wonder if anyone might be able to shed some light on this, hoping it's going to be something simple in the end.

Hi, can you send me the relevant SR(s) in a PM?
I'll have someone take a look at this.

Okay so it turns out that you have to issues and sign the certificate from the cert authority server. Seems a bit odd to have to do it that way. I've not got round to doing this as of yet.  It seems our partner already closed the ticket with CheckPoint anyway. 

Thank you for the response, appreciated

Okay, so it appears that a self signed cert still isn't working. I've asked for the ticket to be re-opened with our partner three times and they're not responding. What I've asked for is if they could elaborate on what exact attributes the cert needs.
