rootDN problems with slapd-config

[Dave Schneider <Dave.Schneider@e2open.com>]

I'm having problems getting the rootDN working when using slapd-config 
form of configuration, while the "exact" same configuration using 
slapd.conf works fine.  Here are my stripped down test versions of the 
two configurations (hashed password is 'secret' from slappasswd):

slapd.d/cn=e2config.ldif:
-------------------------
dn: cn=config
objectClass: olcGlobal
cn: config
olcArgsFile: /var/openldap/run/slapd.args
olcPidFile: /var/openldap/run/slapd.pid

dn: cn=schema,cn=config
objectClass: olcSchemaConfig
cn: schema

include: file:///var/openldap/schema/core.ldif
include: file:///var/openldap/schema/cosine.ldif

dn: olcDatabase=frontend,cn=config
objectClass: olcDatabaseConfig
objectClass: olcFrontendConfig
olcDatabase: frontend

dn: olcDatabase=mdb,cn=config
objectClass: olcDatabaseConfig
objectClass: olcMdbConfig
olcDatabase: mdb
olcMaxsize: 1073741824
olcSuffix: dc=com
olcRootDN: cn=reader,dc=com
olcRootPW: {SSHA}RIC5hnBuWr4t857KR+dzTEOF/ekQaIVx
olcDbDirectory: /var/openldap/data
olcDbIndex: objectClass eq
olcDbIndex: dc eq
olcDbIndex: cn eq


slapd.conf:
-----------
include     /var/openldap/schema/core.schema
include     /var/openldap/schema/cosine.schema

backend     mdb

pidfile     /var/openldap/run/slapd.pid
argsfile    /var/openldap/run/slapd.args

database    mdb
maxsize     1073741824
suffix      dc=com
rootdn      cn=reader,dc=com
rootpw      {SSHA}RIC5hnBuWr4t857KR+dzTEOF/ekQaIVx
directory   /var/openldap/data
index       objectClass eq
index       dc eq
index       cn eq


When I run a simple search for slapd running with the slapd.conf 
configuration I get:

$ ldapsearch -D cn=reader,dc=com -w secret -x -LLL -b dc=com -s base dc=*
dn: dc=com
objectClass: top
objectClass: domain
dc: com

But when I run the same search with the slapd.d configuration I get:

$ ldapsearch  -D cn=reader,dc=com -w secret -x -LLL -b dc=com -s base dc=*
ldap_bind: Invalid DN syntax (34)
    additional info: invalid DN

Debug output on the server side isn't giving much info in addition to 
what's already displayed on the client:

57bf52df conn=1000 op=0 do_bind: invalid dn (cn=reader,dc=com)

Any help on what I might be doing wrong is greatly appreciated.  Oh 
yeah, I'm using version 2.4.44.

Thanks,
Dave
