What I would like to do is allow users in my website to login using their Moodle user. I have read all Moodle documentation on web services and have not found a way to do this.
I would also like to automatically authenticate a user who is currently loged-in in Moodle. I didn't find any Moodle web service function that allows me to find out whose session is open (in the same browser), although I don't know if this can be done without adding a security risk.
Thanks in advance!
