Enrolment: AutoEnrol
enrol_autoenrol
Adds functionality to automatically enrol users onto a course, either as they log into your Moodle site or as they acess a course. This plugin is primarily intended for use on courses which you want all users to be able to access but can also be configured for more advanced purposes.

When added to a course this enrolment plugin can enrol users onto a course automatically, either as they log into your Moodle site or as they click on the course. It is intended for use on site-wide courses such as "Moodle Help" or "Learner Voice".
In addition the plugin has advanced functionality to support autmatically grouping and filtering users based upon their attributes. Depending on how your user accounts are set
up this may help you to give access to certain user groups.
Configuration of the plugin is managed by two permissions which allow administrators to easily control who has access to the plugin.

How about adding an option to allow for auto un-enrolments, if a user has done nothing (no activities?) in the course for a configurable amount of days? This would (to some extent) eliminate the scenarios where a user just want to "check out"/test a course, not planning to do anything, skewing the data.
Let me know what you think - I might even be able to help out (code-wise).
Thanks!

I'm getting the following error when installing... Error Missing English language folder
I'm running Moodle 2.5.2+ (Build: 20131025)
Capability "enrol/autoenrol:config" was not found! This has to be fixed in code.
line 389 of /lib/accesslib.php: call to debugging()
line 178 of /enrol/autoenrol/lib.php: call to has_capability()
line 229 of /enrol/instances.php: call to enrol_autoenrol_plugin->get_newinstance_link()
Any ideas how to resolve?
i need to find the AUTO ENROL Configuration just like in the screen shots at the top of this screen.. could anyone tell me were this is located. i am using version 2.3 or 2.5. the plugin installed fine. thanks
You probably just need to enable Auto enrol.
Goto:
Settings-->Site administration-->Plugins-->Enrolments-->Manage enrol plugins.
this missing English language folder error is caused by there not being a PHP closing tag in the language file contained in /lang/en
Just open it up in the text editor of your choice and add "?> "to the end of the file (without quotes). save and attempt to reinstall.
Thank's for the attention, Moises.
