build ldap tree with same meta and db suffix

[Aleks <al-openldap@none.at>]

Hi dear list members.

I need to create the following ldap-tree

####
dc=example
  dc=customers-ext,dc=example
    dc=MetaOrgTree01,dc=customers-ext,dc=example
    dc=MetaOrgTree02,dc=customers-ext,dc=example
        ...
    dc=MetaOrgTree0n
  dc=customers,dc=example
    dc=MetaOrgTree01,dc=customers,dc=example
    dc=MetaOrgTree02,dc=customers,dc=example
        ...
    dc=MetaOrgTree0n
  dc=appuser,dc=example # < this is a mdb
    uid=bindUser
###############

I was able to create the base setup with the following commands.

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/local/BDB/lib
/opt/local/openldap-2.4.41/sbin/slapadd -F 
/opt/local/conf/openldap/ldap.example.at/ -l 
ldifs/initial_ldap.example.at.ldif -n0

/opt/local/openldap-2.4.41/libexec/slapd -l local5 -F 
/opt/local/conf/openldap/ldap.example.at/ -h "ldap://0.0.0.0:10689 
ldapi://%2fvar%2fopt%2fopenldap%2frun%2fslapd-ldap.sock"

/opt/local/openldap-2.4.41/bin/ldapmodify -D 'cn=config' -w <PASSWORD> 
-H ldapi://%2fvar%2fopt%2fopenldap%2frun%2fslapd-ldap.sock -v  -f  
meta-ldifs/MetaOrgTree01_meta.ldif

and now I'm not able to create the dc tree ( 
add_and_build_root_dc_tree.ldif )

/opt/local/openldap-2.4.41/bin/ldapmodify -D 'cn=config' -w <PASSWORD> 
-H ldapi://%2fvar%2fopt%2fopenldap%2frun%2fslapd-ldap.sock -v  -f 
add_and_build_root_dc_tree.ldif
ldap_initialize( 
ldapi://%2fvar%2fopt%2fopenldap%2frun%2fslapd-ldap.sock/??base )
add objectClass:
        top
        dcObject
        organization
add o:
        example
add description:
        MyOrg
add dc:
        parent
adding new entry "dc=example"
ldap_add: Server is unwilling to perform (53)
        additional info: no global superior knowledge
##################

When I create a "olcDatabase=mdb,cn=config"

with

olcSuffix: dc=example

I'm able to create everything but when I try to add another meta target 
in the db suffix I get the message following message

adding new entry "olcDatabase={5}meta,cn=config"
ldap_add: Other (e.g., implementation specific) error (80)
        additional info: <olcSuffix> namingContext 
"dc=MetaOrgTree02,dc=customers,dc=example" already served by a preceding 
mdb database

Which is clear as the doc say this.

http://www.openldap.org/software/man.cgi?query=slapd-meta&sektion=5&apropos=0&manpath=OpenLDAP+2.4-Release

#########
These slapd.conf options apply to the META backend database.  That  is,
       they  must follow a "database meta" line and come before any 
subsequent
       "backend" or "database" lines.
#########

But how was expected to add another meta entry in a running and working 
system?

Please can anyone help me to find a working solution.

The used ldifs:

I hope I have explained the setup and the question understandable.
Maybe I think not ldap-isch enough

Thanks everybody for help.

Best regards
