RE: Access is denied - GetEffectiveRightsFromAcl

Hi Max,

Do you get this error for all folders/files? If not, can you post the DACL
of the problematic folder/file? It's possible that LocalSystem does not
have the permissions you need.

Also, have you tried your code on other machines? Does the problem only
occur on this specific machine? If you restart your machine, does the
problem still exist?

Another possibility is that the S4U call to Kerberos fails.

Apart from the actual problem, it's just a bad approach to call
GetEffectiveRightsFromAcl for yourself. The recommended solution is just
opening the file in the mode you need it, and deal with the error.

Thanks.

Best regards,
Jeffrey Tan
