I have what it looks like, a NAMCD issue.

Scenario:

Remote Branch A (Kimberley):
SLES10SP2-OES2/SP2 Server
128K ISDN Line
Branch Container partitioned
R/W Copy of Branch partition on above BRANCH A server

Root Servers:
SLES10SP2-OES2/SP2 Server
Datacentre
10.7.100.254 (<root> Master)
10.7.100.220 (Slave <root> Server)

Dedicated Services Container for LUM
.ou=LUM.o=Services (Partitioned, ONLY copies on MASTER/SLAVE)
- This container contains:
- admingroup
- LUMldapuser (account used when adding servers to Tree = S to <root>)
- UNIX Config

Trace Information (Couple of Lines):
