bepe,
i have the previous mediawiki single signon integration (
https://vborg.vbsupport.ru/showthread.php?t=213102 ).
it works fine with the differently capitalized usernames (ie, converts usernames in mediawiki with first letter capitalized).
so have shared connects already. by installing this mod, will the existing linkage be broken (ie, would a new username be recreated?) can you not edit this similar to the previous mod, so that the capitalization of the usernames does not make a diff.
in vbulletin, the field is not case specific, so ABCD, Abcd, abcd are the evaluated as the same username. not so in mediawiki.
