I've just upgraded to Moodle 2.5 and want to create a token for a particular user. I created the course, enrolled some users to it and tried to create a token for a user.
On menu Site administration -> Plugins -> Web services -> Manage tokens when I choose the user and click to perform the token, the moodle system prints:
The user hasn't the required capability to use this service and link to: http://docs.moodle.org/25/en/error/moodle/nocapabilitytousethisservice
Anyone knows how to solve this problem?
