Moodle - LDAP between schools?
We locally host our own Moodle installation and are thinking about hosting seperate Moodle sites for some of our local Primary Schools. The hosting itself isn't a problem, but how the schools then authenticate to the Moodle installation is.
I know that an option of manual usernames and/or email address authentication is possible, but neither of those are options I want to explore (one school doesn't have email for pupils and manual would be fiddly!)
Would it be theoretically possible to allow LDAP authentication beween the primary school and our site?
Currently our sites aren't within the same AD site and I wouldn't want to change that at this point.
Would simply opening up port 389/636 between each of our sites (restricting access to and from specific IP addresses for security) allow LDAP authentication to work?
Has anyone tried this already?
