iNotes Sync Manager and login with shortname

Dear all,

Whe are using iNotes Web Access sinds rel. 5. Our users are used to use their shortname to login in the iNotes Sync Manager. Recently we upgraded from Domino Rel. 5.0.11 to Rel.6.0.2. Now the users have to put in their complete name instead of the shortname to login the Sync Manager. Online they can still use their shortname (“Internet Authentication” is set to “More name variations with lower security”).

Is there a way to change it back?

Thanks in advance,
