ASP.NET Configuration Tool Issue

Question

Dear Code Masters,

 I hope this mail meet you all in good health.

 

I have a web application that i developed for my client,the application is working fine. The application is divided into three folders 

1. Admin
2. Personel
3. Accounts
4. and the Root
   

I also create three roles for the application using ASPNET Configuration Tool the roles are :

1.  r_Admin
2. r_Staff
3. r_Acct

They are all working on my development computer, but when i deploy the application to my client computers and i enter the user name and password for each of the roles it reject it.

all the autentication and authorisation details are stored on my database as i don't want it creating another ASPNET.mdf for me.

 

why is it like that, please is their any thing am not doing right, i need your help.

 

thank you all
