Hi, we are programming a Typo3 - extension for a single-sign-on for multiple backend-applications, but we have problems with this piece of code from customer.pl : # -- # get groups # -- my %GroupData = $CommonObject{GroupObject}->GroupUserList( Result => 'HASH', Type => 'rw', UserID => $UserData{UserID}, ); foreach (keys %GroupData) { $UserData{"UserIsGroup[$GroupData{$_}]"} = 'Yes'; } What is this used for ? Customers have no groups i think ...or is it for AgentCanBeCustomer ? <- btw. i dont understand how this is meant to be used, any help/info welcome !!! By now we think our problem results from the fact that 'customer.pl' is not called by a browser but by another script... is there any information needed that comes from the browser ? thx Dennis
