[Samba] Samba 4.5.0 dbcheck problems

[Chris Alavoine]

Hi all,

I've recently upgraded all our DC's (we have 9 spread over various global
Sites) to 4.5.0.

I run a dbcheck on our FSMO-owner DC once per day from a cron job and this
threw up a ton of errors on the first pass after the upgrade. After running
it several times with the --fix flag I've got the errors down to 603 but
these last errors are refusing to be removed.

Here is an example of each type:

Example1:
*ERROR: incorrect GUID component for member in object
CN=examplegroup,OU=Groups,DC=example,DC=internal,DC=com -
<GUID=77ad92b5ade70e449dcc481624928310>;<RMD_ADDTIME=130393476680000000>;<RMD_CHANGETIME=130976799640000000>;<RMD_FLAGS=1>;<RMD_INVOCID=98307faefea70749933e6946b1b14420>;<RMD_LOCAL_USN=1445979>;<RMD_ORIGINATING_USN=303848>;<RMD_VERSION=1>;<SID=010500000000000515000000e8e83f391df4408a63c6a6b4d25a0000>;CN=simon.test,CN=Users,DC=example,DC=internal,DC=com*

Example2:
*ERROR: incorrect DN string component for member in object
CN=admin-group-001,OU=Groups,DC=example,DC=internal,DC=com -
<GUID=38370cfc-6751-49bb-945e-d2b5e028f0f3>;<RMD_ADDTIME=130941544260000000>;<RMD_CHANGETIME=130941560040000000>;<RMD_FLAGS=1>;<RMD_INVOCID=a65d0f39-311e-4031-aa56-a8585bfc1b8f>;<RMD_LOCAL_USN=1443123>;<RMD_ORIGINATING_USN=1443123>;<RMD_VERSION=1>;<SID=S-1-5-21-960489704-2319512605-3030828643-1219569>;CN=user.test,OU=Test
OU,DC=example,DC=internal,DC=com*

Example3:
*unable to find object for DN
CN=test.user2,CN=Users,DC=example,DC=internal,DC=com - (No such Base DN:
CN=test.user2,CN=Users,DC=example,DC=internal,DC=com)*
*Not removing dangling forward link*

I have edited these entries to maintain anonymity.

Any ideas on how to remove these errors?

Replication appears to be working fine between all DCs (aside from one that
is showing a WERR_BADFILE error, although I don't think this is related),
we are able to use the domain as normal and performance seems good. Would
be nice to clean up these errors though.

Thanks,
Chris.
