I have a SP 2010 set up using claims based authentication and the Microsoft.Office.Server.Security.LdapMembershipProvider provider. Everything for user authentication works perfectly but when I try to change a user's password in code it fails with "Method Not Implemented".
After searching around the internet it has become apparent that the LdapMembershipProvider is extremely limited and allows for almost no interaction and modification of user accounts beyond basic authentication; so my question is this: is there an alternative to the LdapMembershipProvider class? Or, is there a way in code to change a user's password with the LdapMembershipProvider? The LDAP store is Active Directory.
