[Samba] Samba 4.1.7 ldapcmp msDS-NcType Error comparing DCs

Dear all,

Running  samba-tool ldapcmp on my both DCs samba 4.1.7  leads to the output
:


    Attributes found only in ldap://s4master:
        msDS-NcType
        serverState
    FAILED

How to deal with this?
I am missing something?

AD DC are not exact copies of each others. There are some attributes 
that are not synchronized.

according to [1], msDS-NcType has the flag FLAG_ATTR_NOT_REPLICATED

from [2] : "nonreplicated attribute: An attribute whose values are not 
replicated between naming context (NC) replicas. The nonreplicated 
attributes of an object are, in effect, local variables of the domain 
controller (DC) hosting the NC replica containing that object, since 
changes to these attributes have no effect outside that DC."

For serverState, I guess it is a similar situation.

You can ignore those message using the --filter=msDS-NcType to your 
ldapcmp command line.

Cheers,

Denis
