Minimal Membership Provider for SQL Server

Requirements

A minimal membership provider requires a dedicated table to keep track of user names and passwords.

This is a sample “Users” table with “identity” primary key.

A user table with "identity" primary key allows keeping tracking of user names and passwords

SQL:

create table Users
(
     UserID int not null identity primary key,
     UserName nvarchar(128) not null,
     "Password" nvarchar(128) not null
)

Here is how the table may look with a “unique identifier” primary key.

A user table with "unique identifier" primary key allows keeping tracking of user names and passwords

SQL:

create table Users
(
    UserID uniqueidentifier not null default newid() primary key,
    UserName nvarchar(128) not null,
    "Password" nvarchar(128) not null
)

User roles are hardcoded in the minimal Role Provider implementation.

Configuration

Create a table in your database using one of  the scripts specified above.

Select the project name on the start page of the application generator and choose Settings.

Proceed to Authentication and Membership.

Select “Enable custom membership and role providers” option and enter the following configuration settings.

table Users=Users
column [int|uiid] UserID = UserId
column [text] UserName = UserName
column [text] Password = Password

role Administrators = admin
role Users = admin, user
role Everybody = *

The configuration maps logical table Users required for membership provider implementation to the physical database table Users. It also defines three user roles – Administrators, Users, and Everybody.

Generate the project.
