I tried another method ,and works .(User AD user)
still don't know why the demo user store not working
I use the AD user viewadmin
1.I simply move the viewadmin from to another
Original is dc=view usrs,dc=view group
I move it to the dc=view group (which has only one dc)
2. Be care the testing user must have the complete information (email/description) ,so it will be successfully configured
