recently in the project customers are using the CRM2013SP1 version, so the plug-in registrar uses the corresponding 6.1.1.1143, the tragic things began.
In the plugin to register step, the tool has a run in User's context option, through the setting of this option we can choose the identity to execute the step, with the most of course the calling user, that is, who triggered the plugin with whose permissions to execute, But sometimes a system operation, regardless of who to trigger the plug-in will need the identity of the admin to execute, the choice here is an account with admin privileges can be.
However, I encountered a problem with the 6.1.1.1143 version of the plugin,run in the user's context option only a calling user, I can not select the other system account, and then on this issue various query various attempts, Finally found that this is Microsoft's a damn bug.
I tried the following several versions of the plug-in registration tool, CRM2013 6.1.0.519, CRM2015 7.0.0.2332, CRM2016 8.0.0.7113, there is no problem described above, so the title of the version of the plug-in register of the students hurriedly deleted.
