Every object in the meta backend is virtual.  Your configuration is hosed,
because you state that the database is serving the naming context
"ou=A,o=B,c=C", but then you configure URI directives to start serving the
naming context from its leaves.  If you want the root entry to be defined,
you need to configure (at least) one URI to serve it.  The "right"
approach would be to configure exactly one URI to serve the root entry,
and optionally use subtree-exclude or subtree-include to restrict the use
of that URI's subtree. Something like

database meta
suffix ou=A,o=B,c=C
# ...
uri ldap://server1/ou=A,o=B,c=C
subtree-include "ou=S1,ou=A,o=B,c=C"
#...
uri ldap://server2/ou=S2,ou=A,o=B,c=C

should do the trick.
