Microsoft Active Directory Encryption

It’s
rare for any organization to be without at least one Microsoft Active
Directory® (AD) server, and for many it is a fundamental part of their
identity infrastructure. While it has many advantages, Microsoft Active Directory
also has limitations and complexities that make an infrastructure
difficult to manage and administer.
Encryption is one area that can create problems for Microsoft Active
Directory administrators. While an Active Directory instance may perform
well without encryption, enabling TLS/SSL often brings a major hit,
potentially impacting the entire infrastructure. TLS/SSL encryption is
necessary for authentication across an insecure channel such as the
Internet, so administrators who provision access for “external” parties
are often forced to consider upgrading the Active Directory domain’s
hardware. And, although it uses LDAP for communications, Microsoft
Active Directory demands a unique format and encoding for user password
change requests, so a “standard” LDAP modify operation cannot be used.
While not a problem for Windows-based tools, any user management
applications designed for a normal LDAP environment may be incapable of
sending password requests in the required format and therefore cannot be
integrated into the infrastructure.

Symlabs
Virtual Directory Server is a powerful middleware application that can
behave as an LDAP proxy, creating a highly efficient TLS/SSL termination
point to securely provision Active Directory access for external
clients. This allows independently configured front-end and back-end
connectivity, so TLS/SSL can be offered to external applications without
enabling it in Active Directory, thus avoiding the performance penalty.
Symlabs Virtual Directory Server can also manipulate data within the
network packets it routes between client applications and back-end
servers, so any request or response can be modified on-the-fly so it
conforms to expectations. Simple scriplets can be created to intercept
password change requests and establish compatibility between AD and LDAP
user management tools. Also included is an ACL plug-in that can further
improve overall security by adding data access controls specifically
for external users without impacting the existing AD access rules.
