  2. Agenda • Introduction • Membership Service • Login Controls • Role Management Service 2

  3. Role Based Security • Most business applications require role-based security. • Role management lets you create groups of users as a unit • Roles give flexibility to change permissions and add and remove users. • Each Web page in the Web application can be assigned a security level • As you define more access rules for your application, roles become a more convenient way to apply the changes to groups of users. 3

  4. Membership Service • Manages users and credentials • Simplifies forms authentication • Provider-based for flexible data storage 4

  5. Membership Schema Controls Login LoginStatus LoginView Other Controls Membership API Membership MembershipUser Membership Providers SqlMembershipProvider Other Membership Providers Membership Data SQL Server SQL Server Express Other Data Stores 5

  6. Key Membership Methods

  7. Creating New Users try { Membership.CreateUser ("Jeff", "imbatman!", "jeff@microsoft.com"); } catch (MembershipCreateUserException e) { // Find out why CreateUser failed switch (e.StatusCode) { case MembershipCreateStatus.DuplicateUsername: ... case MembershipCreateStatus.DuplicateEmail: ... case MembershipCreateStatus.InvalidPassword: ... default: ... } } 7

  8. The MembershipUser Class • Represents individual users registered in the membership data store • Returned by Membership methods such as GetUser and CreateUser 8

  9. Key MembershipUser Methods

  10. Configuring the Membership Service <membership defaultProvider="AspNetSqlMembershipProvider" userIsOnlineTimeWindow = "00:15:00" hashAlgorithmType = "[SHA1|MD5]" > <providers> ... </providers> </membership> 10

  11. Login Controls

  12. Using the Login Control <html> <body> <form runat="server"> <asp:Login RunAt="server" /> </form> </body> </html> 12

  13. The LoginView Control • Displays content differently to different users depending on: • Whether user is authenticated • If user is authenticated, the role memberships he or she is assigned • Template-driven • <AnonymousTemplate> • <LoggedInTemplate> • <RoleGroups> and <ContentTemplate> 13

  14. Using LoginView <asp:LoginView ID="LoginView1" Runat="server"> <AnonymousTemplate> <!-- Content seen by unauthenticated users --> </AnonymousTemplate> <LoggedInTemplate> <!-- Content seen by authenticated users --> </LoggedInTemplate> <RoleGroups> <asp:RoleGroup Roles="Administrators"> <ContentTemplate> <!-- Content seen by authenticated users who are administrators --> </ContentTemplate> </asp:RoleGroup> ... </RoleGroups> </asp:LoginView> 14

  15. Role Management Service • Role-based security in a box • Simplifies adding role-based security to sites that employ forms authentication • Provider-based for flexible data storage 15

  16. Role Management Schema Controls Login LoginStatus LoginView Other Controls Roles API Roles Role Providers SqlRoleProvider Other Role Providers Roles Data SQL Server SQL Server Express Other Data Stores 16

  17. The Roles Class • Provides static methods for performing key role management tasks • Includes read-only static properties for acquiring data about provider settings 17

  18. Key Roles Methods

  19. Creating a New Role if (!Roles.RoleExists ("Developers")) { Roles.CreateRole ("Developers"); } Adding a User to a Role string name = Membership.GetUser ().Username; // Get current user Roles.AddUserToRole (name, "Developers"); // Add current user to role 19

  20. Configuring the Role Manager <roleManager enabled="[true|false]" defaultProvider="AspNetSqlRoleProvider" createPersistentCookie="[true|false]" cacheRolesInCookie="[true|false]" cookieName=".ASPXROLES" cookieTimeout="00:30:00" cookiePath="/" cookieRequireSSL="[true|false]" cookieSlidingExpiration="[true|true]" cookieProtection="[None|Validation|Encryption|All]" domain="" maxCachedResults="25" > <providers> ... </providers> </roleManager> 20

  21. Role Management Providers • Role management is provider-based • Ships with three role providers: • AuthorizationStoreRoleProvider (Authorization Manager, or "AzMan") • SqlRoleProvider (SQL Server) • WindowsTokenRoleProvider (Windows) • Use custom providers for other data stores 21

  22. Configuring SqlRoleProvider <roleManager defaultProvider="AspNetSqlRoleProvider" ...> <providers> <add applicationName="/" connectionStringName="LocalSqlServer" name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider, System.Web, ..." /> </providers> </roleManager> 22
