Hi again Moodles!

My issue is already resolved this Monday 11/29.

Before making the previous post, i was trying this external database enrollment feature, and i figured out that, if i would use the inner user and course tables, the correct value to enter in "enrol_localcoursefield" is "id" (the primary key in the course table); and in "enrol_localuserfield" is "id" too (the primary key in the user table); and these are the right values to put in.

My first test didn't work because i put the IP address of the same machine where moodle is installed (this works but for a host that are not the same where moodle is).

If you have the external database in the same machine, you must set "localhost" in the hostname field. If it is on another host, just put on the IP address.

The remaining "enrol_remotecoursefield" and "enrol_remoteuserfield" is for the fields of the extenal table on the external database i'm using.

Thank you all anyway!

Leonardo.
