[Auth_ldap] AD upgrade breaks auth_ldap?

[Rohit Kumar Mehta]

Hi guys, we have two separate Apache 1.3 servers using Active Directory 
for authentication (via auth_ldap 1.6.0-3)
They have been working for months problem-free.

Since patching our DCs last night they have both broken.  I have not 
looked into this thoroughly yet.  Wondering
if anyone has seen anything similar?

Our apache2 server using modauthldap (9/7/2003) works fine.

Here is a snippet of our error log of a failing server:
