problem with openldap identity assertion to AD server

[John Uhlig <juhlig@parc.com>]

Hello.

I am new to this list so please forgive any protocol violations :)

I am starting with simple steps towards our goal to use the openldap server translucent overlay config to merge AD authentication for people at our company with local ldap account authentication for 
non-company people.

I am using openldap 2.4.23  on RHEL6 server.

At this point, the ldap server can access our AD servers with anonymous bind but I need authenticated access to get more information.

I have been using variations of  the "Identity Assertion" steps from the openldap FAQ page (http://www.openldap.org/faq/data/cache/532.html) without success.

I am initially trying the simplest config e.g. bindmethod=simple with a valid AD account/password for this access.

I have included my current minimalist slapd.conf file if of any help.

If anyone can point me to sample working configuration file(s) or provide any recommendations, I would appreciate it.

thanks,
John.

# Sample security restrictions
#    Require integrity protection (prevent hijacking)
#    Require 112-bit (3DES or better) encryption for updates
#    Require 63-bit encryption for simple bind
# security ssf=1 update_ssf=112 simple_bind=64

# Sample access control policy:
#    Root DSE: allow anyone to read it
#    Subschema (sub)entry DSE: allow anyone to read it
#    Other DSEs:
#        Allow self write access
#        Allow authenticated users read access
#        Allow anonymous users to authenticate
#    Directives needed to implement policy:
# access to dn.base="" by * read
# access to dn.base="cn=Subschema" by * read
# access to *
#    by self write
#    by users read
#    by anonymous auth
#
# if no access controls are present, the default policy
# allows anyone and everyone to read anything but restricts
# updates to rootdn.  (e.g., "access to * by * read")
#
# rootdn can always read and write EVERYTHING!
