Secure Copy - 'The security ID structure is invalid' error when copying data
This error is generated when an attempt to read or write security descriptor information fails because an invalid security identifier (SID) was encountered in the security descriptor information.
Alternate Error
"This security ID may not be assigned as the owner of this object."
This error is generated when the security descriptor's ownership information is invalid.
This error is uncommon and has been reported only in those cases where a non-Windows powered Network Attached Storage (NAS) system is included as either a source or destination system.
When Secure Copy copies a file the security descriptor information contained within the file is also copied.
Note: Use of the term 'file' applies to folders as well, since Windows simply treats folders as a special type of file.
A security descriptor includes four components:
The DACL and SACL components always exist in a security descriptor, but do not necessarily contain information.
SACL entries follow these same guidelines, and inheritance flags are also contained within the DACL and SACL components.
Current Working Theory
Solution:
Secure Copy is simply reporting the response it received from the NAS device when it attempted to read or write the security descriptor information, so there is no workaround that can be implemented using Secure Copy to eliminate occurances of the error.
However, since data is copied successfully, Security Explorer can be used to modify ownership and DACL information once the data migration is finished.
