Security group provisioning - Remove on uninstall

Jump to solution

Hello,

our customer is using App Portal 2021R2 and SCCM as deployment technology.
According to the administration guide, the security groups provisioning functions as follows:

 

secgroups.png

"In the event the program is uninstalled using SCCM App Portal, the user will be removed from the listed security groups."

Adding users to the security group works like a charm, but on choosing uninstall for this catalog object, it seems like App Portal just tries to add the user to the group again, which then fails because the user already is in this group:

We configured the catalog object to add to group on request / approval.
Is there something we are missing, like a specific config, or is our interpretation of this function just wrong?
Thanks in advance for your support, if you need more information, just let me know and I'll provide it.

Best regards,
Tim

This has been a limitation for some time (contrary to the documentation). All hope is not lost, however...  I might suggest creating a command action which calls the command Remove-ADGroupMember. As arguments, you would pass in the group name and the UserName. You could define the group name as a custom variable on your catalog item, and you could pass in ##UserName## as the user name argument.. The powershell script would likely look similar to the following:

param(
[string]$groupName, #specify a custom variable on the catalog item with the group name
[string]$userName #pass the variable ##UserName##
)
Remove-ADGroupMember -identity $groupName -Members $userName -Confirm:$false


You would add this command action to the "on success uninstall" event of your catalog item.

Let me know if you have any questions on the subject..

Another option is to use a simple SOAP web service to do the same as what Charlie suggested.  Within Flexera Services, we've created a SOAP web service with a number of helpful utility methods in it.  One of those is a method called AddRemoveADGroupMember.  I've include code from a recent version of this web service.  If you'd like to try it, just save the code as GCS_CustomWebService.asmx in the <App Portal>\Web\WS folder and then add the web service in the admin UI.

Thank you both for your quick answers, I'll try the PowerShell script first, as it seems to be more "leightweight" and easier to manage, atleast for me. If I get it to work I'll mark it as solution otherwise I probably come back for more questions. 😉
