I would try to get a trace of the failure, you will probably note a dropped
(or filtered) packet or really oddly formated ldap query filter.

Subject: [ActiveDir] AD LDAP Error

I have a W2K based AD that has a trust with a MIT based realm. In that realm
there is a Oracle app that uses the openldap tools to manipulate user
objects in AD based on changes to the user entries in the database. 
  The Oracle app uses a Kerberos authenticated ldapsearch and ldapmodify to
make these changes.

As part of QA in moving the Oracle app from Tru64 to RedHat Enterprise Linux
the Oracle people have been creating new user objects and modifying existing
user objects in our test domain. Modifying objects works just fine. Creating
new ones fail on occasion.

The openldap tools give a useful

ldif_record() = 81

which points to a i/o error. It doesn't say exactly what it is.

The error (after enabling extended logging) in the directory server log is
equally useful

Event Type:    Warning
Event Source:    NTDS LDAP
Event Category:    LDAP Interface
Event ID:    1216
Date:        10/27/2005
Time:        8:00:30 AM
User:        N/A
Computer:    DC3
Description:
The LDAP server closed a socket to a client because of an error condition,
87.  (Internal ID c0603b6::1577).

1216 points to a couple different errors - none of which seem to fit.

My first conversation with Microsoft got me nowhere. I'm calling them back
as soon as our access issues get worked out.

Any ideas?
