--- Comment #4 from Kunal Mehta (Legoktm) legoktm.wikipedia@gmail.com --- After rereading the LDAP link, you're probably right in that the it's the actual mediawiki login that is forcing uppercase, nonetheless the file name that pywiki attempts to find should be case correct irrelevant of the username supplied or returned. My thought for that fix has to do with correctly saving the *-login.data cookie with the username found in user-config.py.
