CSInvalidUserException - No such user

System

Hi,

For some strange reason we're getting the following error for all users defined on our system in the servletd_out.log file. Users are defined in the "roles" files and can login to TeamSite!! Any idea why this might be happening?

[http-8080-Processor24] ERROR com.interwoven.ui.teamsite.access.UserPreferencesImpl (TEAMSITE\cigdema) - Error saving 1 properties (14 byte) to EDB
