Can't create new users in 9.0 - Unable to load plug-in assembly

(0) ShareShare
ReportReport
Posted on by Community Member

Just installed 9.0.2.3034 in three dev vm's, app01 is running front end and email router, async01 is running asynchronous and sandbox services, sql01 is database.  I was able to create a new org just fine, enable claims and ifd, then login.  When I go to create another user I get the following error.

unable-to-load-plug_2D00_in-assembly.png

I have verified the following:

-I'm logging into crm as the deployment administrator who is also a local admin on all three servers and has sysadmin role in sql

-The deployment administrator account, the sandbox service account, and the asynchronous service account have full control to the "C:\Program Files\Dynamics 365\server\bin\assembly\Microsoft.Dynamics.Service.Plugins.dll' and all of the child objects.

-I've tried setting the sandbox service and asynchronous service to use 'SYSTEM' instead of specific domain accounts.

-All crm services are running

-Rebooted all servers

Here is the trace log:

    RE: Can't create new users in 9.0 - Unable to load plug-in assembly

    If the step where the application is trying to load this dll happens in a synchronous context then it might be that the service account attempting to load the dll is the application service (the account that the Dynamics IIS website is  running under). This is usually a different account from the ones you mentioned having already tried raising privileges for. Can you check to see if you are running a different user as the application service and if so, try giving that account privileges to the dll folder?

    Hi ,

    Which version of SDK your are using ?

    Download the SDK from here and try again - https://xrm.tools/SDK

    RE: Can't create new users in 9.0 - Unable to load plug-in assembly

    The issue ended up being that on the app server the C:\Program Files\Dynamics 365\Server\bin\assembly folder was not inheriting security permissions from C:\Program Files\Dynamics 365\Server\bin.  After I enabled inheritance I was able to add a new user.  Inheritance added the following users to ntfs security: all application packages, all restricted application packages, creator owner, system, trusted installer.  Those were not there when inheritance was disabled.

    Confirmed that this fixed the issue. Need Microsoft to confirm this as a valid workaround. Why can't this work properly out of the box???

    RE: Can't create new users in 9.0 - Unable to load plug-in assembly

    Hello,

    This, and adding permissions to the CRM app pool service account on this folder did the trick. What I don't get is why MS installed their own assemblies on disk instead on database. I've checked on an 8.2.3 server and they aren't on the folder, as it should be.

    I needed to do iisreset after enabling the inheritance.
