Sean,

I really appreciate your help with this!

Here's my slapd.conf:

#
# See slapd.conf(5) for details on configuration options.
# This file should NOT be world readable.
#
include		/etc/openldap/schema/core.schema
include		/etc/openldap/schema/cosine.schema
include		/etc/openldap/schema/inetorgperson.schema
include		/etc/openldap/schema/nis.schema

# Allow LDAPv2 client connections.  This is NOT the default.
allow bind_v2

# Do not enable referrals until AFTER you have a working directory
# service AND an understanding of referrals.
#referral	ldap://root.openldap.org

pidfile		/var/run/slapd.pid
argsfile	/var/run/slapd.args

# Load dynamic backend modules:
# modulepath	/usr/sbin/openldap
# moduleload	back_bdb.la
# moduleload	back_ldap.la
# moduleload	back_ldbm.la
# moduleload	back_passwd.la
# moduleload	back_shell.la

# The next three lines allow use of TLS for encrypting connections using a
# dummy test certificate which you can generate by changing to
# /usr/share/ssl/certs, running "make slapd.pem", and fixing permissions on
# slapd.pem so that the ldap user or group can read it.  Your client
software
# may balk at self-signed certificates, however.
# TLSCACertificateFile /usr/share/ssl/certs/ca-bundle.crt
# TLSCertificateFile /usr/share/ssl/certs/slapd.pem
# TLSCertificateKeyFile /usr/share/ssl/certs/slapd.pem

# 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!

#######################################################################
# ldbm and/or bdb database definitions
#######################################################################

database	bdb
suffix		"dc=palmettodomains,dc=com"
#rootdn		"cn=Manager,dc=palmetodomains,dc=com"
rootdn		"uid=root,cn=palmettodomains.com,cn=digest-md5,cn=auth"
# Cleartext passwords, especially for the rootdn, should
# be avoided.  See slappasswd(8) and slapd.conf(5) for details.
# Use of strong authentication encouraged.
# rootpw		secret
# rootpw		"{SHA}xqFH8zno0DblfNcUXu2A/6U3txQ="

# The database directory MUST exist prior to running slapd AND 
# should only be accessible by the slapd and slap tools.
# Mode 700 recommended.
directory	/var/lib/ldap

# Indices to maintain for this database
index objectClass                       eq,pres
index ou,cn,mail,surname,givenname      eq,pres,sub
index uidNumber,gidNumber,loginShell    eq,pres
index uid,memberUid                     eq,pres,sub
index nisMapName,nisMapEntry            eq,pres,sub

# Replicas of this database
#replogfile /var/lib/ldap/openldap-master-replog
#replica host=ldap-1.example.com:389 starttls=critical
#     bindmethod=sasl saslmech=GSSAPI
#     authcId=host/ldap-master.example.com at EXAMPLE.COM

sasl-regexp uid=(.*),cn=palmettodomains,cn=DIGEST-MD5,cn=auth uid=$1

It's pretty much the default config.  Anything jump out at you?

What should be in ldap.conf?  Everything is commented out by default.

Thanks!!
