OK, I've got OpenLDAP installed and working.  Now I'm itching to use
it.  I started with the example in the quick-start guide.  I edited my
slapd.conf to look like what I have listed further below.  I then
created an example.ldif that looks like this:

dn: dc=my-domain,dc=com
objectclass: dcObject
objectclass: organization
o: My-Domain Company
dc: my-domain
dn: cn=Manager,dc=my-domain,dc=com
objectclass: organizationalRole
cn: Manager

When I run 

ldapadd -x -D "cn=Manager,dc=my-domain,dc=com" -W -f example.ldif

I get:
Enter LDAP Password:
adding new entry "dc=my-domain,dc=com "
ldap_add: Invalid syntax
additional info: objectclass: value #0 contains invalid data

ldif_record() = 21

Any ideas on why this would happen?  I'm a complete newbie here so be
gentle ;-)
