Trying to whitelist a kernel extension for an agent I'm trying to install. I'm using Mojave as the client machine and Profile Manger on a Mac server I've set up. I can enroll the client machine fine in Profile Manager, and it can receive canned settings like external device restrictions etc, but I can't seem to get custom settings to work correctly.
The process to get this to work is I've been uploading the following:

as a .plist file using "com.apple.syspolicy.kernel-extension-policy" as a policy domain into Profile Manager, saving the config on profile manager, then downloading a .mobileconfig file.
I move that .mobileconfig file to the already enrolled client, and run the file and except the prompts to install the profile into profile->system prefs. This goes successfully and I see green "verified" at the top
BUT
it doesn't result in adding the team ID into the DB (at least not so far).
I'm using the following code to try to read the sqlite DB to verify:
#!/bin/sh
# Gather list of User Approved Kernel Extensions. 20180313 DM
folder=.
file=checkKEXTs.csv
# Create folder
/bin/mkdir -p ${folder}
/usr/sbin/chown root:admin ${folder}
/bin/chmod 755 ${folder}
/usr/bin/sqlite3 -csv /var/db/SystemPolicyConfiguration/KextPolicy "select team_id,bundle_id from kext_policy" > ${folder}/${file}
exit 0
I do see entries, but they're for VMware. Never for the above products.
Searching Console, I see the following:

These log messages appear right at the time of that I install the .mobileconfig file each time, so I suspect there's a correlation. I've tried repairing permissions without success. About the only thing I didn't do is try this on another Mac which I may try as well. I've also tried using a .plist file that only includes configurations for bundle ID's or Team ID's respectively (not combined as in above) without success.
The worst part is that I'm having difficulties troubleshooting the issue. I just don't understand the underlying mechanisms very well so I'm open to troubleshooting tips. It may also be that there's something wrong with my .plist code but I'm just not seeing it. Very open to suggestions there as well. It seems like my test machine is trying to commit the settings, but it's just not working.
Another thing: I noticed errors related to the file "DetachedSignatures" in the logs as well and copied a file from another machine onto the test one in the /var/db (I think) folder and the errors went away. No idea if they're related.
As you can tell, I'm sorta grasping at straws here. Hoping and praying the moderator Gods are kind to me and allow me to keep this post active so I can get help. Thank you so much in advance for reading this and hopefully with your help, I can get beyond this. It's probably something silly I'm missing.
