samba - May 2013 - "Failed to modify SPNs on … error in module acl: insufficient access rights" error

My samba4 (latest git, @ 5f826415) logs seem to be littered with this error:


[2013/05/02 13:10:39,  0]
../source4/rpc_server/drsuapi/writespn.c:237(dcesrv_drsuapi_DsWriteAccountSpn)
  Failed to modify SPNs on
CN=AIO6,CN=Computers,DC=corp,DC=example,DC=com: error in module acl:
insufficient access rights (50)


Any thoughts on debugging this / fixing this issue?


It's only this one machine CN (AIO6). None of the other ~15 identical
machines show up in the logs, only this one.



I see a few (old) threads suggesting this error/bug was fixed, e.g.
