Access denied to a security provider on a signed applet

Question

Hi,
I'm having permissions problems to work with a security provider.
The security provider is already installed at java.security. In fact, at Netbeans when debbuging the app it's working perfectly.
If I'm working the provider in an signed applet, then there are errors.
Even, I have created a .jar file and I have saved in the /ext directory, wich by default in the java.policy file has got all security permissions.
grant codeBase "file:${{java.ext.dirs}}/*" {
permission java.security.AllPermission;
Even with these granted permissions, I'm getting problems to work with the security provider that I have installed. Also, with these permissions I should be able to install the security provider.

Fails in the line where the KeyStore is loading:(Pin is correct)
KeyStore myKeyStore=null;
Provider p = Security.getProvider("SunPKCS11-Provider-Name");
myKeyStore = KeyStore.getInstance("PKCS11",p);
char[] pinData = pin.toCharArray();
myKeyStore.load(null, pinData);
Any help would be apreciated.
Thank you.
Bye

Answer 1

Thank you for your information, Frank, as it clarifies part of my confusion. However, there are a couple more loose ends I'd love to address before I mark your responses as answers.
Do backup and restore privileges apply at all over a network mount created via "net use"?
The network mount requires a username and password for the destination machine. Assuming the destination machine is a Windows box with a simple CIFS share, how does this user affect our permissions and access? Do we end up effectively impersonating this
user, or is the access check still done with our sync process's run-as user?
We require that both our configured run-as user for our sync process *and* the credentials passed to the network mount be administrator users of the local system and destination system, respectively, meaning they're in of the "BUILTIN\Administrators,
S-1-5-32-544" group.
On re-syncs, the destination file will exist and since we don't have the ability to read the ACL in all cases (we're running as one user, the file is owned by another user, and we aren't specified in the ACL in any way), we aren't able to determine if the
file has changed. Is it possible to determine the owner of this file in this case? Preferably, we'd obtain the entire SDDL.
My proposed plan is to interpret access denied as a difference requiring re-sync, resulting in us taking ownership of the file, granting ourselves access, determining if there are data differences, and then re-syncing the metadata as appropriate.
