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!!
