[Samba] domain join failure - error during DRS repl ADD: No objectClass found
Hello,
I am trying to join a third domain controller to an existing Samba 4 domain
(sernet samba 4.2.1-17.el6.x86_64) and we're hitting a problem that looks
like some bad replication data on certain objects. We get part way through
replicating the tree and then it dies on a Sudo Rule object:
[root at dc03 ~]# /usr/bin/samba-tool domain join EXAMPLE.COM DC -U
Administrator --password=xxxxxxxxxxxx --dns-backend=BIND9_DLZ
...
Failed to apply records: replmd_replicated_apply_add: error during DRS repl ADD:
No objectClass found in replPropertyMetaData for
CN=rule,OU=SUDOers,DC=example,DC=com!
: Object class violation
Failed to commit objects: WERR_GENERAL_FAILURE
Join failed - cleaning up

256, in replicate
schema=schema, req_level=req_level, req=req)
However, when I check the data that the domain join is complaining about on the
two existing domain controllers, it appears to be present and ok, so I don't
think we are talking about https://bugzilla.samba.org/show_bug.cgi?id=10398
(plus we are > 4.1 here):
[root at dc01 ~]# ldbsearch -H /var/lib/samba/private/sam.ldb -b
"CN=rule,OU=SUDOers,DC=example,DC=com" -s base objectClass
...
# record 1
dn: CN=rule,OU=SUDOers,DC=example,DC=com
objectClass: top
objectClass: sudoRole
If I run a dbcheck I see a number of these for various objects:
Values/Order of values do/does not match: ...
ERROR: Normalisation error for attribute 'objectClass' in ...
But none of the out of objects affected are what blows up the domain join. If I
look at the meta data in binary of the Sudo Rule it does mentions objectClass,
however there is a lot of other UNKNOWN_ENUM_VALUE entries in that array for
this entry. When I compare it to other standard AD objects in the LDAP tree,
there are no unknown values.
[root at dc01 ~]# ldbsearch -H /var/lib/samba/private/sam.ldb -b
"CN=rule,OU=SUDOers,DC=example,DC=com" -s base replPropertyMetaData

Does anyone have any ideas about what is interfering with the domain join, or
where to debug further?
Thanks,

At the same time we would have built and joined DC2.
