Syncrepl with subordinate databases



I have multiple sites that I am trying to sync up to a global server.  Each site is configured (striped down) as:

############################################################################
# mdb database for o=chi01,ou=studios,dc=methodstudios,dc=net
############################################################################
database        mdb
suffix          "o=chi01,ou=studios,dc=methodstudios,dc=net"

# Save the time that the entry gets modified
lastmod         on

# Subordinate of the ou=studios,dc=methodstudios,dc=net database below
subordinate advertise

overlay                 syncprov
syncprov-reloadhint     TRUE
syncprov-checkpoint       100 5

############################################################################
# mdb database for ou=studios,dc=methodstudios,dc=net
############################################################################
database        mdb
suffix          "ou=studios,dc=methodstudios,dc=net"


The above is my configuration for Chicago.  I have similar ones for New York (ny01) and Los Angeles (la01)
On my global server I am trying to use sync replication to clone each site.  The global server is configured (striped down) as:

############################################################################

############################################################################

Now that I have the configuration out of the way.  Syncrepl on the global server is failing on chi01.  The chi01 server syslog has

Oct 23 18:41:35 boote01-chi01 slapd[19324]: conn=1000 op=2 SRCH base="o=chi01,ou=studios,dc=methodstudios,dc=net" scope=2 deref=0 filter="(objectClass=*)"

Looking at the ny01 server (ldapsearch -x -h ny01 -b o=ny01,ou=studios,dc=methodstudios,dc=net -s base +) where syncrepl is working

Looking at the global server root of the glued database (ldapsearch -x -h global -b ou=studios,dc=methodstudios,dc=net -s base +):
# studios, methodstudios.net
dn: ou=studios,dc=methodstudios,dc=net
structuralObjectClass: organizationalUnit
entryUUID: cc769b12-d084-1032-86fe-a1b1821abdab

entryDN: ou=studios,dc=methodstudios,dc=net
subschemaSubentry: cn=Subschema
hasSubordinates: FALSE


So after all that.  Is the syncrepl from chi01 using the contextCSN from the root of the glued database?  It seems all the syncrepl from all the sites fail unless they have the latest change.  How do you handle syncrepl on glued databases?
