Thread:Extension talk:GoogleAppsAuthentification/Unable to change user permissions of auto-created accounts/reply (3)

I added the following to LocalSettings.php:

$wgUserrightsInterwikiDelimiter = '#'
 * 1) Allow @ in username (# as delimiter for database instead of @)

This changes the interwiki delimiter to a # instead of an @, allowing you to have @ in your username without trouble. I doubt anybody uses interwiki rights management except the Wikimedia Foundation itself; I really wish they just had interwiki disabled by default. Oh well.
