# MIM service change detection trigger

#### Summary

AutoSync contains an out of box trigger that can be used on the MIM Service management agent, which will automatically detect changes in the MIM service, and trigger a delta import.

#### Configuration

The MIM service trigger is only available on a MIM Service MA. From the triggers page, select `Add trigger...` and the MIM service change detection trigger will be available from the drop down list. Please note that only a single instance of the MIM service trigger can be added.

The trigger will pre-populate the hostname from the MA configuration, and set the default check interval to every 60 seconds.

#### Permissions

The AutoSync service account requires permission to read the following attributes on all `Request` objects

* msidmCompletedTime

You can create the set and MPR manually, or use the `Create set and MPR...` button on the trigger configuration page to do this automatically. Note that the logged on user must have administrative rights in the MIM service to create the set and MPR.
