Hello, I have 2 samba DCs. DC1 with FSMO role and DC2. These days, when I use dbcheck in DC1 ,I got the following error: # samba-tool dbcheck --cross-ncs Checking 4419 objects ERROR: incorrect DN SID component for member in object CN=Domain Users,CN=Users,DC=adagene,DC=cn - <GUID=c5c33d48-226b-4105-9c69-0506a22d3a15>;<RMD_ADDTIME=131526914300000000> ;<RMD_CHANGETIME=131526914750000000>;<RMD_FLAGS=1>;<RMD_INVOCID=4f720a27-5a1 9-4fba-8e89-9f59f7c3533e>;<RMD_LOCAL_USN=102599>;<RMD_ORIGINATING_USN=102599>;<RMD_VERSION=1>;CN=jack,OU=Users,OU=Suzhou,DC=adagene,DC=cnNot fixing SID component mismatch Please use --fix to fix these errors Checked 4419 objects (1 errors) ---In DC2 ,there is no error.

Hi, It appears to be an error in dbcheck, where we're making assertions on the primaryGroupID despite the fact that it is dealing with an inactive link. It should be safe to ignore, and should disappear once the stale link is deleted permanently after the usual tombstone period. There probably needs to be a bug filed though, to make sure we fix this unintended error. Cheers, Garming On 10/02/18 01:34, 徐星亚 via samba wrote:> Hello, I have 2 samba DCs.

[Samba] A db error that dbcheck tool can't fix
Garming, Thanks for your reply. Could I deleted the stale link manually, Or the
bug will be fixed in next release ?

Hi,
It appears to be an error in dbcheck, where we're making assertions on
the primaryGroupID despite the fact that it is dealing with an inactive
link. It should be safe to ignore, and should disappear once the stale
link is deleted permanently after the usual tombstone period. There
probably needs to be a bug filed though, to make sure we fix this
unintended error.
