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

What you say makes sense - I didn't know that MediaWiki accounts did interpret the @ sign somehow - anyway, it is easy to fix - just change the line that says " $username = $googleAccount['email']; ", with something like " $username = preg_replace('/@.*/', '', $googleAccount['email']); " or something similar....
