[Samba] Use repadmin /showobjmeta would caused samba 4.3.0 fault

I had a AD with 4 Win2003 DC. Now I use a samba4 server as a additional DC.
Samba4 server system version: ubuntu 15.04
Samba version: samba 4.3.0
The replication from win2003 DC to samba4 DC was success. But have
some problem from samba4 DC to win2003 DC. I can run "samba-tool drs
showrepl" without error. But in log.samba it can found many message
like:

[2015/10/09 12:53:11.562088,  0]
../source4/rpc_server/drsuapi/getncchanges.c:259(get_nc_changes_build_object)
  ../source4/rpc_server/drsuapi/getncchanges.c:259: Failed to find
attribute in schema for attrid 33816623 mentioned in
replPropertyMetaData of CN=officeuser,OU=MailUsers,DC=mydomain,DC=org

When I run repadmin /showobjmeta in windows try to get metadata
information, it can success when target is the win2003 dc, like:

repadmin /showobjmeta "win2003dc1"
"CN=officeuser,OU=MailUsers,DC=mydomain,DC=org"
...

But it will fault out whan target is samba4 dc, like:

repadmin /showobjmeta "samba4dc"
"CN=officeuser,OU=MailUsers,DC=mydomain,DC=org"
DsReplicaGetInfo() failed with status 1359 (0x54f):
    Can't retrieve message string 1359 (0x54f), error 1815.

There are some error log in log.samba of samba4 dc:

Quite likely it is.  Thankfully that routine appears to be only
available to administrators.

Can you please file a bug, with exact steps to reproduce (I couldn't
get it to reproduce) and a gdb backtrace?

You can mark comments and attachments private to the samba team in the
bugzilla if you need to.

Thanks,

Andrew Bartlett

Thanks for the reply.
I reported the bug in bugzilla, but I don't exactly know how to gdb
backtrace. So I did not add attachments yet. I should add the
attachments when I figure out how to do it. Thanks a lot.
