[Aaron Wells <1556692@xxxxxxxxxxxxxxxxxx>]

This is the second bug we've had in the past year that was caused by
get_new_username() truncating usernames to 30 characters. (The earlier
one was Bug 1486699, which added the param to change the default new
username length, and set it to 40 for SAML.)

I wonder if it would make more sense to just update get_new_username()
so that it instead truncates usernames to 255 characters, that being the
length of usr.username and auth_remote_user.username.

Title:
  Problem with MNet usernames greater than 30 characters, when
  $CFG->usersuniquebyusername is used

Bug description:
  This bug occurs when the following set of circumstances are in use:

  1. MNet is set up, with users coming *into* Mahara
  2. Mnet is set to auto-create user accounts in Mahara
  3. $cfg->usersuniquebyusername is set to "True", which means that users are logged in by matching them against usr.username rather than auth_remote_user.remoteusername

  In this case, users coming from Mnet are provisioned in Mahara with a
  unique username based on their Moodle username, but truncated to 30
  characters. Then on subsequent login attempts, their truncated Mahara
  username doesn't match their Moodle username, and they do not log in
  correctly.
