SCPreferencesLock issue?

[Jeremy Matthews]

For some reason, I can't seem to get a lock....was wondering if anyone else has 
been here before:

AuthorizationRef auth = nil;
        OSStatus authErr = noErr;
        
        AuthorizationFlags rootFlags = kAuthorizationFlagDefaults 
        | kAuthorizationFlagExtendRights 
        | kAuthorizationFlagInteractionAllowed 
        | kAuthorizationFlagPreAuthorize;
        
        authErr = AuthorizationCreate(nil, kAuthorizationEmptyEnvironment, 
rootFlags, &auth);
        
        SCPreferencesRef prefs;
        //SCPreferencesRef prefsWithAuth;
        
        CFStringRef appName = CFSTR("com.test.testapp");
        CFStringRef computerName = CFSTR("macbookpro2");
        
        SCPreferencesLock(prefs, NO);
                
        if ( geteuid() != 0 )
        {
        prefs = SCPreferencesCreateWithAuthorization(NULL, appName, NULL, auth);
        }
    else
        {
                prefs = SCPreferencesCreate(NULL, appName, NULL);       
        }
        
        if (prefs == nil) 
                NSLog(@"InterfaceConfig failure: SCPreferencesCreate failed");
        
        SCPreferencesLock(prefs, NO);
         
        if (prefs && SCPreferencesLock(prefs, TRUE))
        {
                //We got a write lock, that means we can do whatever
                //we want to 
/Library/Preferences/SystemConfiguration/preferences.plist
                NSLog(@"LOCK OBTAINED");
        } else {
                NSLog(@"LOCK NOT OBTAINED");
        }

        SCPreferencesSetComputerName(prefs, computerName, 
kCFStringEncodingUTF8);

        SCPreferencesCommitChanges(prefs);
                
     if(!SCPreferencesCommitChanges(prefs))
    {
        NSLog(@"can't commit changes");
    }
                
        SCPreferencesApplyChanges(prefs);
        if(!SCPreferencesApplyChanges(prefs))
    {
        NSLog(@"can't apply changes");
    }
        
    SCPreferencesUnlock(prefs);
    CFRelease(prefs);
