Hi Andy,
I searched via ldbsearch for deleted objects and found the entries. I
then changed the tombstone timeout to a smaller value (10days)= and did
restart samba. After some minutes I searched again and now the entries for :
bb22ce3e-2d94-47e2-aa29-11a2a0e4e2f3
60bb6abe-2d08-4f5f-81db-787f6e23706b
619df70c-abc9-4644-bff6-35809664bbd9
have disappeared from the deleted objects. Unfortunately this seems to
have made things worse as I do now get the following failure:
==== OUTBOUND NEIGHBORS ====
ERROR(runtime): DsReplicaGetInfo of type -2 failed - (8442,
'WERR_DS_DRA_INTERNAL_ERROR')
File
"/usr/local/samba/lib/python2.7/site-packages/samba/netcmd/drs.py", line
116, in drsuapi_ReplicaInfo
(info_type, info) = ctx.drsuapi.DsReplicaGetInfo(ctx.drsuapi_handle,
1, req1)
in log.samba I can see the following error:
[2014/05/08 19:34:49.159705, 0]
../source4/dsdb/kcc/kcc_drs_replica_info.c:680(fill_neighbor_from_repsTo)
../source4/dsdb/kcc/kcc_drs_replica_info.c:680: Failed to find DN for
neighbor GUID 23db6774-c155-4e5f-a793-07e9c772ddc4
Does anybody have an idea how to get rid of the orphaned neighbour
GUIDs. Where can I find those entries ?
Thank you for your kind help
best regards
Andreas
