You use the
System.Web.Security.ActiveDirectoryMembershipProvider class in an ASP.NET 2.0 application to provide membership services by using an Active Directory server or an Active Directory Application Mode (ADAM) server. However, you receive an exception that resembles the following:
Exception type:
System.DirectoryServices.Protocols.DirectoryOperationException
Message: The server cannot handle directory requests.
For more information about the stack trace output, see the More information section.
This problem occurs because ASP.NET 2.0 tries to put a
Lightweight Directory Access Protocol (LDAP) connection into fast bind mode.
However, because the LDAP connection is already bound to the directory service, the LDAP connection cannot be put into fast bind mode. Therefore, the directory request fails.
A supported hotfix is available from Microsoft.
