UserId Not Working View The Full Article SYMPTOMS: Sorry. Authentication Failed error I need a UserID RESOLUTION: When the Authentication Failed message is received either the login name or the password is incorrect. Make sure the user has the correct userid using the Userid Lookup Page http://winblade1.clemson.edu/userid/default.aspx and their CUID number. To get someones userid use their CUID to look it up with the Userid Lookup Page http://winblade1.clemson.edu/userid/default.aspx . If they donand39t have their CUID use their SS with the IDMSDC utility in Host Explorer using the sclm command.
