Blocking chrome extensions but whitelist specific ones

Super Contributor

Hi all,

 

Im having issues white listing specific extensions and also blocking others too! 

Iv added the Chrome ADMX and have force deploy on specific apps  which is working but below are the config for the ones that dont work

 

Blocking

OMA-URI:

./Device/Vendor/MSFT/Policy/Config/Chrome~Policy~googlechrome~Extensions/ExtensionInstallBlacklist

 

String: 

<enabled/> <data id="ExtensionInstallBlacklistDesc" value="1&#xF000;*"/>

 

Whitelisting

 

OMA-URI: ./Device/Vendor/MSFT/Policy/Config/Chrome~Policy~googlechrome~Extensions/ExtensionInstallWhitelist

 

String: <enabled/> <data id="ExtensionInstallWhitelistDesc" value="1&#xF000;alhngdkjgnedakdlnamimgfihgkmenbh&#xF000;2&#xF000;jbldkhfglmgeihlcaeliadhipokhocnm"/>

 

(I used this link: https://www.inthecloud247.com/manage-google-chrome-settings-with-microsoft-intune/ )

 

 Please help!

hi,

Are you receiving any specific errors when looking at the device management enterprise event log?

I get this: MDM ConfigurationManager: Command failure status. Configuration Source ID: (2F8AAF4A-BBC7-4009-A02F-27F93C36E6DA), Enrollment Name: (MDMDeviceWithAAD), Provider Name: (Policy), Command Type: (Add: from Replace or Add), CSP URI: (./Device/Vendor/MSFT/Policy/ConfigOperations/ADMXInstall/Receiver/Properties/Policy/FakePolicy/Version), Result: (The system cannot find the file specified.).

@Rudy_Ooms_MVP Hi, Any ideas? Or is it worth trying to do these via powershell/regedit instead? 

I will take a look at it tonight.. This afternoon I am needed at my daughter birthday party... :)
No problem! Thank you!

Happy Birthday to your Daughter!

Could you check out your chrome admx it contains this part and if it arrived at your device (policymanager /registry)

 

<policy class="Both" displayName="$(string.ExtensionInstallBlacklist)" explainText="$(string.ExtensionInstallBlacklist_Explain)" key="Software\Policies\Google\Chrome" name="ExtensionInstallBlacklist" presentation="$(presentation.ExtensionInstallBlacklist)">
<parentCategory ref="Extensions"/>
<supportedOn ref="SUPPORTED_WIN7"/>
<elements>
<list id="ExtensionInstallBlacklistDesc" key="Software\Policies\Google\Chrome\ExtensionInstallBlacklist" valuePrefix=""/>
</elements>
</policy>

 

Hi @Rudy_Ooms_MVP 

 

So I have checked the ADMX and all is there:

Here is the policy I set for blacklist too:

Here is the registry via the device:

Any ideas where Im going wrong? Is it best we do this via powershell or is it clear where I have made a mistake? 

 

Thanks again for your continued help

 

@AB21805 

Hi could you also post the out put  of this key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\current\device\Chrome~Policy~googlechrome~Extensions

 

like

Rudy_Ooms_0-1634120744858.png

 

And this key \SOFTWARE\Policies\Google\Chrome\ExtensionInstallBlacklist

Hi @Rudy_Ooms_MVP 

 

The first screenshot I have:

Second and third I cant seen to find exactly what you want but here are the screnshots:

Any ideas? 

The provider id could be different.. there has to be some information about chrome init..

@AB21805 For our extension management in Edge (and Chrome) we use the "Configure extension management settings" option containing a JSON with the all extensions blocked and then the individual ones we want available listed with either "force_installed" for those we want installed and not touchable by the user, "allowed" for those that user can go and install from the Edge store (and/or Chrome store) and "normal_installed" for those that we pre-install but the user can enable/disable as needed. We've found this handles extensions overall better than using the separate settings entries.

 

Below is our JSON as an example and here's the documentation link (and this is also included in Intune): https://docs.microsoft.com/en-us/DeployEdge/microsoft-edge-policies#configure-extension-management-s...

{"*":{"installation_mode":"blocked","blocked_install_message":"Installation of Edge extensions requires approval"},"jmfbfggikgbdccejjilikgnfdjnpmlfe":{"installation_mode":"normal_installed","update_url":"https://clients2.google.com/service/update2/crx"},"lfmcehohgifnaodaogknapedjiaoebgo":{"installation_mode":"allowed"},"ekhagklcjbdpajgpjgmbionohlpdbjgc":{"installation_mode":"allowed"},"pjjladfifbaokjdckiedipnkaemnjffa":{"installation_mode":"allowed"},"oiigbmnaadbkfbmpbfijlflahbdbdgdf":{"installation_mode":"allowed"},"mooikfkahbdckldjjndioackbalphokd":{"installation_mode":"allowed"},"ddaloccgjfibfpkalenodgehlhkgoahe":{"installation_mode":"allowed"},"jbbplnpkjmmeebjpijfedlgcdilocofh":{"installation_mode":"allowed"},"fjgncogppolhfdpijihbpfmeohpaadpc":{"installation_mode":"allowed"},"glnpjglilkicbckjpbgcfkogebgllemb":{"installation_mode":"allowed"},"dpncpimghfponcpjkgihfikppbbhchil":{"installation_mode":"allowed"},"dkgencfabioofgdmhhjljpkbbchbikbh":{"installation_mode":"allowed"},"bomfdkbfpdhijjbeoicnfhjbdhncfhig":{"installation_mode":"allowed"},"ikdddppdhmjcdfgilpnbkdeggoiicjgo":{"installation_mode":"normal_installed","update_url":"https://edge.microsoft.com/extensionwebstorebase/v1/crx"},"nffeahffadlikbdfgngjocbcicdbikpa":{"installation_mode":"normal_installed","update_url":"https://clients2.google.com/service/update2/crx"},"pbnfcaobikkbealhienfilklacghhgoi":{"installation_mode":"allowed"},"hdgegmlancchhhlkkddoiedlklgocffm":{"installation_mode":"allowed"},"lhdoppojpmngadmnindnejefpokejbdd":{"installation_mode":"allowed"},"inahogkhlkbkjkkaleonemeijihmfagi":{"installation_mode":"allowed"},"elgalmkoelokbchhkhacckoklkejnhcd":{"installation_mode":"allowed"},"pbjjkligggfmakdaogkfomddhfmpjeni":{"installation_mode":"allowed"},"hbfacnnpimgddoojjaonnnbeljegicfl":{"installation_mode":"normal_installed","update_url":"https://edge.microsoft.com/extensionwebstorebase/v1/crx"},"maafgiompdekodanheihhgilkjchcakm":{"installation_mode":"normal_installed","update_url":"https://outlook.office.com/owa/SmimeCrxUpdate.ashx"},"mbcgpelmjnpfbdnkbebdlfjmeckpnhha":{"installation_mode":"allowed"},"llnckjibglpbknibkglkapgkcioabomp":{"installation_mode":"allowed"},"jaleebmaoohbjjohjlfmihkkopgfibne":{"installation_mode":"allowed"},"cdgjgpahklmdkojkkdgmckgmbnheolnl":{"installation_mode":"allowed"},"mbopgmdnpcbohhpnfglgohlbhfongabi":{"installation_mode":"allowed"},"ghbhpcookfemncgoinjblecnilppimih":{"installation_mode":"allowed"},"jalhapcnkijacfbnbcicimhafnllongh":{"installation_mode":"allowed"},"gpphkfbcpidddadnkolkpfckpihlkkil":{"installation_mode":"allowed"},"nnkgneoiohoecpdiaponcejilbhhikei":{"installation_mode":"allowed"},"gjpfobpafnhjhbajcjgccbbdofdckggg":{"installation_mode":"allowed"},"ggknodeapenofhidkfgfncfoeclcfoom":{"installation_mode":"allowed"},"ifoakfbpdcdoeenechcleahebpibofpc":{"installation_mode":"allowed"},"ndaciljfdnekbnmcpjidoebejglcjidc":{"installation_mode":"allowed"},"ogcgkffhplmphkaahpmffcafajaocjbd":{"installation_mode":"allowed"},"pmapbmihblakhgodloklimjbaoohkiop":{"installation_mode":"allowed"},"gmhjclgpamdccpomoomknemhmmialaae":{"installation_mode":"allowed"},"lajjpilliikppcbaghjehndpfdiiphbe":{"installation_mode":"allowed"},"pjocddipjlkokifpnnbmjemienmelhak":{"installation_mode":"allowed"},"feolagkacappiaieohahjkeaikhjjcfa":{"installation_mode":"allowed"},"ildbfpaelempeokjfldpclbfggjkhdhl":{"installation_mode":"allowed"},"nhdogjmejiglipccpnnnanhbledajbpd":{"installation_mode":"allowed"},"hicljaeiiajaecppcpfphnibmddpehlk":{"installation_mode":"allowed"},"kpjldaeddnfokhmgdlmpdlecmobaonnj":{"installation_mode":"allowed"},"banejkelfpdmmmfobepfdnbmbbnecnol":{"installation_mode":"allowed"}}

 

Ahh. its indeed missing the "knowhow" /settings.
Did you create a separate policy/csp for it or did you add it to the existing csp?

Hi @Rudy_Ooms_MVP 

 

I have added to existing:

What happens when you create a separate policy/csp for it?
