Posting prior to SR hoping the community benefits from the answers if resolved here:

Issue:
(4) server (3) node cluster (all cluster nodes are OES Linux)
Cluster node will not join cluster (ERROR: failed to init this node's configuration)
Cluster node will not re-create cluster node objects (documented procedure followed to remove cluster node objects)

Facts:
OES 2 SP2 cluster nodes updated to SP3 (issue appears)
OES 2 SP2 cluster nodes updated to post SP3 updates (issue persists)
YAST and OES Install and Config throw no errors or warning other than for the proxy user info below
sbdutil -f locates cluster SBD on all three nodes
Server SSL infrastructure/certs are good
eDirectory time synchronisation is good
All three cluster nodes have a replica containing the cluster objects
eDirectory object relationships for all replicas are good
OES Common Proxy user is properly configured with use for NCS and CASA
Selection of OES Proxy User in re-config dialogs results in error about invalid user
Selection of eDir admin user for NCS proxy results in same failure
All OES Common Proxy users and the eDir tree admin user are members of the "CLUSTER-NAME_MGMT_GRP" eDir group
/opt/novell/ncs/bin/ncs-config.py -init gives good results
/etc/opt/novell/ncs/nodename gives good results
/etc/opt/novell/ncs/clstrlib.conf is being modified when YAST is used to re-config
/var/opt/novell/ncs/nodes.xml has no "dsml" entries (file has only XML headers basically)
/var/log/messages has no NCS entries on failed novell-ncs script run or install/reconfig events (even with debug enabled)
/var/opt/novell/install/ncslog contains the following:
