Active Directory Membership Provider for EPiCommerce
The first step in inserting the custom AD provider is to add a new CSPROJ file. You may name it whatever you'd like, but in keeping with EPiServer naming conventions, it is recommended you name it "EPiServer.Commerce.ADMembershipProvider".
Next, add the following block to the membership section of your web.config (please note that the value of attributeMapUsername must be 'sAMAccountName'. That is not a "call it what you'd like" value)
1: <membership defaultProvider="ActiveDirectoryMembershipProvider" userIsOnlineTimeWindow="10">
2: <providers>
3: <clear />
4: <add name="ActiveDirectoryMembershipProvider"
5: type="EPiServer.Commerce.ADMembershipProvider.CustomADProvider, EPiServer.Commerce.ADMembershipProvider"
6: connectionStringName="ActiveDirectoryProviderConnection"
7: connectionUsername="domain\username"
8: connectionPassword="password"
9: enableSearchMethods="true"
10: attributeMapUsername="sAMAccountName" />
1: <add name="ActiveDirectoryProviderConnection" connectionString="LDAP://yourDoman"/>

Finally, create a new class under your new project. This may also be called whatever you'd like, but naming conventions recommend "CustomADProvider". The important thing about this class is that
it inherits System.Web.Security.ActiveDirectoryMembershipProvider, the methods of which we will override with the below code.
