 <connectionStrings>
 <add name="ADConnectionString" connectionString="LDAP://abc.com/DC=abc,DC=com" />
 </connectionStrings>

 <membership defaultProvider="MyADMembershipProvider">
 <providers>
 <add
 name="MyADMembershipProvider"
 type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0,Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
 connectionStringName="ADConnectionString"
 connectionProtection="Secure"
 connectionUsername="user"
 connectionPassword="pwd"
 attributeMapUsername="sAMAccountName"
 enableSearchMethods="true"
 attributeMapEmail="mail"
 />
 </providers>
 </membership>


 <!--Make sure you have fomrs authentication enabled.-->
 <authentication mode="Forms">
 <forms loginUrl="~/Account/LogOn" timeout="2880" />
 </authentication>

 {
 MembershipUser mu = Membership.GetUser("testuser");
 string sx = mu.Email.ToString();
 }
