LDAP server setup and operation

I am an absolute, total, ignorant newbie when it comes to LDAP, but I'd like to set up a server for my address books.  I am running RH 7.1, and openldap is installed.  I went to openldap.org and tried to follow the "easy" instructions to set up a simple-minded, proof-that-it-is-working database. Unfortunately, I can't get past square one.  When I follow their instructions to run ldapadd and create a simple database, I get what appears to be an authentication error:

#
ldapadd -x -D "cn=Manager,dc=localhost,dc=localdomain" -W
-f /home/harlow/tmp/test.ldif
Enter LDAP Password: <here I entered the password "secret">
ldap_bind: Invalid credentials
#

Here is my slapd.conf file, which is just a bare-bones edit of the default:

# $OpenLDAP: pkg/ldap/servers/slapd/slapd.conf,v 1.8.8.4 2000/08/26 17:06:18 kurt Exp $
#
# 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
include         /etc/openldap/schema/redhat/rfc822-MailMember.schema
include         /etc/openldap/schema/redhat/autofs.schema
include         /etc/openldap/schema/redhat/kerberosobject.schema

# Define global ACLs to disable default read access.

# 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

#rootdn         "cn=Manager, o=My Organization Name, c=US"
# Cleartext passwords, especially for the rootdn, should

# Use of strong authentication encouraged.

# Indices to maintain
#index  objectClass                             eq

index   cn,mail,surname,givenname               eq,subinitial

As I understand the setup here, it creates a default superuser account called Manager, with a cleartext password "secret".  However as you can see above, it doesn't recognize this.

None of the FAQs seem to provide any insight on troubleshooting, and they are all written for those who already understand.  Any help would be much appreciated.

the  rootpw  is commented out in your slapd.conf, so openldap probably runs without a password for the Manager

Oh man, do I feel dumb.... Anyway, I fixed it and restarted slapd, but still get the same result.  How about some of that other stuff that is commented out, like pidfile and argsfile?  Do I need to uncomment those?  Anything else you can see that I missed?

I'm off from my openldap-on-linux-box, so can only give unprooved hints, sorry.

AFAIK, openldap assign a default passwd to rootdn if not specified elsewhere. Probably it's best to remove the installtion and install it again (or read the docs).

BTW, can you perform a ldapsearch, a) anonymous search without specifying a db, b) a search as specified dn ?

I reinstalled openldap and things seem to work better.  I read all the HOWTOs and FAQs, but man, this stuff is opaque! I am very accustomed to Linux/Unix documentation challenges, but this is the worst ever.  The examples in some of the openldap docs conflict with each other and many of them seem to have been written for earlier versions of the clients, with syntax that is no longer valid.  If I ever figure all this out, I may try to write a new HOWTO myself!

Thanks

Great, the whole (LDAP)world (me too:) is waiting for a usable doc.
LDAP (even Netscape's NDS) is poorly documented, it simply works if setup properly :-|
