I have two Configuration Profiles that deploy certificates:
- SCEP Wi-Fi Certificate (CA)
- 3 CA certificates for Forcepoint endpoint



Both have these settings:
- Distribution Method: Install Automatically
- Level: Computer Level
- Target: Specific Computers: All Managed Clients / Specific Users: none
- No Limitations
- No Exclusions



My setup involve a cluster of two JSS instances, with a limited JSS in the DMZ.



My issue is that certificates disappear intermittently.



Here's the issue I get:

it seems that for whatever reason, the profile is being pushed twice in a row. OS X seems to get confused about that. Anyone saw this?

Hi @ftiff-amaris



There is a line near the top that looks like it tried to remove a certificate, but failed. Then it proceeded to install the Websense certificate.



The only pointer I can see in the log is the error about a trust cert, the validity of which might be changing depending on whether a device is inside or outside the network.

In speaking with @ftiff-amaris, OS X El Capitan less than 10.11.2 may be involved. If the affected computers only run OS X 10.11.0 or 10.11.1, that’s what I’d suspect.



The OS X 10.11.2 release notes have this gem:



“Resolves an issue where reinstalling a configuration profile containing a certificate payload causes the certificates to be removed instead of updated”


In practice, this can result in certificates being removed — and not re-imported — on OS X 10.11 and 10.11.1. If your management and other systems depend upon certificates with a trust chain added by configuration profile(s), this can result in failed TLS connections to those systems. If that’s your JSS, that could mean you have less ability to remediate the problem.



For remediation, I think you’d need to update OS X 10.11.2 or later and re-apply the necessary certificates profiles.



Because OS X 10.11.3 resolves a separate issue with pkg receipts being removed — and that removal can have other implications — I would probably jump to 10.11.3 as a minimum on any managed El Cap workstation.

Thank you very much @jaharmi !
