I am trying to set up an ASP.NET MVC site to use LDAP. I feel like I have everything set up right, but Membership.ValidateUser keeps returning false when I am expecting it to return true. I've read some documentation, like for example this one on AD membership, but one thing I want to make sure I completely understand as I am troubleshooting is this:

Is the defaultProvider attribute value something specific provided by Microsoft? Or is it just an arbitrary name, and we can call it anything?

This is my current web.config setup:

<connectionStrings>
<add name="ADConnectionString" connectionString="LDAP://dc1.dc2.dc3.dc4/DC=dc1,DC=dc2,DC=dc3,DC=dc4" /
</connectionStrings>

<membership defaultProvider="AspNetActiveDirectoryMembershipProvider">
  <providers>
    <clear />
    <add name="AspNetActiveDirectoryMembershipProvider" type="System.Web.Security.ActiveDirectoryMembershipProvider" connectionStringName="ADConnectionString" attributeMapUsername="sAMAccountName" />
  </providers>
</membership>

    You declare your providers (i.e. AspNetActiveDirectoryMembershipProvider) then you define one of them as default via the defaultProvider. If you put in defaultProvider something else than a provider defined it will not work as expected. – StfBln Mar 15 '17 at 14:33
  • @StfBln That makes complete sense. Thank you very much. – Chuck Watson Mar 15 '17 at 14:36
