Ok, looking in the log I've found the problem. The application
is asking for an access mask of 0x1020000, which maps to
READ_CONTROL_ACCESS (which we grant) and SEC_RIGHT_SYSTEM_SECURITY
(ie. access to the system security ACL - the audit ACL) on the
>From this page:
"SACL Access Right
The ACCESS_SYSTEM_SECURITY access right controls the ability to get or set the SACL in an object's security descriptor. The system grants this access right only if the SE_SECURITY_NAME privilege is enabled in the access token of the requesting thread."
We do not support the SE_SECURITY_NAME privilege and don't
allow setting SACLs (we don't support them).
Someone else has already raised this previously. Do your
users have the SE_SECURITY_NAME privilege in their local
tokens (ie. are they allowed to set SACLs on their local
filesystem). Does this happen to non-privileged users ?
A suggestion has been made to ignore the SEC_RIGHT_SYSTEM_SECURITY
request (just mask it out) for filesystem access while
we don't support SACLs, but I'm concerned as to why the
application is trying to request it ?
