Jabber for iOS v14.0.2 - Invalid Certificate was declined

Hello. I am trying to tunnel Cisco Jabber through our enterprise MDM such that external company devices could utilize Jabber services on mobile phones without the use of a full VPN client. So far, I've been successful in added Jabber to application tunnel in MDM and can verify that traffic is being passed via MDM virtual appliance to our backend CUCM. However, I'm getting an error when attempting to login that states an "invalid certificate was declined." 

 

I exported the logs from my mobile phone, but I can't make much out of the error. 

 

Help?

This has been the problem with the mobile devices. You don't get the prompt like windows.

If your organization uses a solution like MDM (Mobile device management) then you can use them to manage the certificates.

The Jabber documentation explains which certificates need to be in the device's trust store for Jabber to work properly, if they're not deployed in advance the user will be prompted to accept or discard/deny? (can't recall the exact wording) the certificate and they need to accept it for Jabber to work.

Are the necessary certificates already in the trust store?

Hi Jaime, thanks for the response.

 

We're currently using self-signed certificates on CUCM servers. And, you're correct, for our Windows clients, users have to accept the certificate (with a warning that it can't be verified) before the login action completes.

 

The difference here is that the mobile client never offers to let a user accept the certificate. It's automatically rejected. Do we know if that's a default behavior or is there a way to change the configuration such that a mobile user is allowed to accept?

If I recall correctly, not that long ago Apple made some changes in the way certificates are handled in their devices, can't recall the exact changes but I believe they affected how certificates were accepted/validated, google about the subject and you'll probably find information related to that.

Thanks, Alok. We do use an MDM solution and it was necessary to configure the MDM backend to allow the prompting of users for invalid certificates.
