Some or all identity references could not be translated

I want to set some access rules to a file. Now when i set the rule, the variable name contains the right username (like: domain\user).

string name = new SecurityIdentifier(rule.IdentityReference.Value).Translate(typeof(NTAccount)).ToString();
accessControl.AddAccessRule(rule);

But the next line throws a IdentityNotMappedException with the message:

Some or all identity references could not be translated.

why I can translate in the first line the IdentityReference to a username, but the second line can't translate it?

Solution

  • ok, I found this solution:

    create the rule, and set the identityReferences to this: new SecurityIdentifier(identity)
