[Serusers] About serweb

Hi everyone: I'm having problems with serweb when I'm trying to login, I mean, when I type http://localhost/serweb/html/user_interface/index.php the screen apears, but when I introduce a user name and a password and press login the same login form screen appears. Could anyone tell me what I'm doing wrong? Thanks in advance Edgar Vidal Edgar Vidal SAS Institute México, S.A. de C.V. Edgar.Vidal(a)sas.com Tel. (52) 55 5000 3814 SAS ... The Power to Know
