[K12OSN] OpenLDAP, again

Thu Aug 19 07:42:23 UTC 2004

OK, the k12ltsp.org site appears unreachable by me, so
I can't look at the HowTo that I know is on the site,
and googling gives me answers that aren't relavent to
me.

I have a computer which has been K12LTSP for a couple
fo years and seen many upgrades.  Right now, it's
running FC3Beta1.  The computer also serves web pages
across  my ADSL via dyndns.org. OpenLDAP and all the
deps are installed, but I can't seem to get it all
working.

What I need is really simple: unified logon and
address info for sessions and several web apps that
are installed and LDAP enabled. I don't need (or want)
any other machines authenticating from this one, just
the clients (which have X on the server) and the web
apps (also on this server).

Here are my .conf files:

/etc/openldap/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!

I have tried the files with both these host settings
and with dc=localhost,dc=localdomain

here is a look at my seesion to migrate:

[root at master /]# service ldap restart Stopping slapd: 
                                          [FAILED]
Checking configuration files for slapd: config file
testing succeeded
Starting slapd:                                       
    [  OK  ]

 but I keep getting the error:

ldap_bind: Can't contact LDAP server (-1)

Thanks in advance
