Dependencies

Sloodle files:

• config.php
• sl_debug.php
• lib/sl_lsllib.php

The following HTTP parameters are required:

• sloodlepwd = the site's Prim Password

6. If the avatar was already registered, check if it is linked to a Moodle account
7. If avatar is not registered at all then:
   1. Create a new Sloodle user (terminate with an error if unsuccessful)
8. If Sloodle user does not have a login security token then:
   1. Generate a new login security token
   2. Store it in the database (terminate with an error if unsuccessful)
9. Construct user authentication URL
10. Render response
11. Terminate script
