newbie question

[Edward Zarecor <edward@indeterminate.org>]

I've searched pretty extensively and implemented a number of 
suggestions, but still haven't been able to get slapd working correctly.

I'm having problems on Redhat 7.1 using the openldap-servers-2.0.11-8 
rpm.  Currently the daemon starts and the following test query returns 
successfully

ldapsearch -x -b '' -s base '(objectclass=*)' namingContexts

version: 2

#
# filter: (objectclass=*)
# requesting: namingContexts
#

#
dn:
namingContexts: dc=myorg,dc=org

# search result
search: 2
result: 0 Success

# numResponses: 2
# numEntries: 1


However, I'm unable to add records to the database using the command:

ldapadd -D "cn=admin,dc=myorg,dc=org" -W -f ./myldif.ldif

after issuing the command I get the message:

ldap_sasl_interactive_bind_s: No such attribute

This is covered briefly in the faqomatic, so I know that my Root DSE has 
been read, but that it contains no supportedSASLMechanism attribute. 
This attribute seems to be beyond the scope of the simple configuration 
files I've seen.  So, I'd appreciate any clues.

Attempting the command while forcing simple authentication yields:

ldap_add: Insufficient access

Thanks in advance for any help.

My slapd.conf file is as follows:

#
# 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
