Requirements
An advanced membership and role provider requires three tables.
One table keeps track of user information. This information includes the UserName, Email, and a Comment. Additional columns allow for implementation of a password question and answer in order to recover a forgotten password. When users are created, they can not be approved by default. Additional information is captured about the most recent login, activity, and change of password. When a user inputs an incorrect password past the limit, the user will become locked out. The number of failed attempts and most recent failed attempt will be stored.
Two tables are required to keep track of roles and associations of users with roles.
These are the advanced membership and role provider tables with “identity” primary keys.
SQL:
create table Users (
UserID int identity not null primary key,
UserName nvarchar(128) not null,
Password nvarchar(128) not null,
Email nvarchar(128),
Comment ntext,
PasswordQuestion nvarchar(256),
PasswordAnswer nvarchar(128),
IsApproved bit not null,
LastActivityDate datetime not null,
LastLoginDate datetime not null,
LastPasswordChangedDate datetime not null,
CreationDate datetime not null,
IsLockedOut bit not null,
LastLockedOutDate datetime not null,
FailedPasswordAttemptCount int not null,
FailedPasswordAttemptWindowStart datetime not null,
FailedPasswordAnswerAttemptCount int not null,
FailedPasswordAnswerAttemptWindowStart datetime not null
)
go
create table Roles (
RoleID int identity not null primary key,
RoleName nvarchar(50)
)
go
create table UserRoles (
UserID int not null,
RoleID int not null,
primary key(UserID, RoleID)
)
go
alter table UserRoles with check add constraint FK_UserRoles_Roles
foreign key (RoleID) references Roles (RoleID)
alter table UserRoles with check add constraint FK_UserRoles_Users
foreign key (UserID) references Users (UserID)
These are the advanced membership and role provider tables with “unique identifier” primary keys.
SQL:
create table Users (
UserID uniqueidentifier not null default newid() primary key,
UserName nvarchar(128) not null,
Password nvarchar(128) not null,
Email nvarchar(128),
Comment ntext,
PasswordQuestion nvarchar(256),
PasswordAnswer nvarchar(128),
IsApproved bit not null,
LastActivityDate datetime not null,
LastLoginDate datetime not null,
LastPasswordChangedDate datetime not null,
CreationDate datetime not null,
IsLockedOut bit not null,
LastLockedOutDate datetime not null,
FailedPasswordAttemptCount int not null,
FailedPasswordAttemptWindowStart datetime not null,
FailedPasswordAnswerAttemptCount int not null,
FailedPasswordAnswerAttemptWindowStart datetime not null
)
go
create table Roles (
RoleID uniqueidentifier not null default newid() primary key,
RoleName nvarchar(50)
)
go
create table UserRoles (
UserID uniqueidentifier not null,
RoleID uniqueidentifier not null,
primary key(UserID, RoleID)
)
go
alter table UserRoles with check add constraint FK_UserRoles_Roles
foreign key (RoleID) references Roles (RoleID)
alter table UserRoles with check add constraint FK_UserRoles_Users
foreign key (UserID) references Users (UserID)
Configuration
Use one of the scripts above to create the membership and role provider tables in your database.
Start Code On Time web application generator, select the project name on the start page, and choose Settings. Select 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
column [text] Email = Email
column [text] Comment = Comment
column [text] PasswordQuestion = PasswordQuestion
column [text] PasswordAnswer = PasswordAnswer
column [bool] IsApproved = IsApproved
column [date] LastActivityDate = LastActivityDate
column [date] LastLoginDate = LastLoginDate
column [date] LastPasswordChangedDate = LastPasswordChangedDate
column [date] CreationDate = CreationDate
column [bool] IsLockedOut = IsLockedOut
column [date] LastLockedOutDate = LastLockedOutDate
column [int] FailedPasswordAttemptCount = FailedPasswordAttemptCount
column [date] FailedPasswordAttemptWindowStart = FailedPasswordAttemptWindowStart
column [int] FailedPasswordAnswerAttemptCount = FailedPasswordAnswerAttemptCount
column [date] FailedPasswordAnswerAttemptWindowStart = FailedPasswordAnswerAttemptWindowStart
table Roles = Roles
column [int|uiid] RoleID = RoleID
column [text] RoleName = RoleName
table UserRoles = UserRoles
column [int|uiid] UserID = UserID
column [int|uiid] RoleID = RoleID
The configuration will guide the code generator in mapping the logical tables Users, Roles, and UserRoles to the physical tables in the database.
Generate the project to create the custom membership and role provider.
