FillClaimsForEntity not called in my custom claim provider

Question

Hi,
I have created a custom claim provider in SharePoint 2013 in order to augment claims with some custom values. It's mostly boilerplate code - nothing special. After deploying and enabling a corresponding farm feature I noticed that the FillClaimsForEntity
method is not called at all. Moreover, other two methods required for augmentation (FillClaimValueTypes and FillClaimTypes) are called only once - when the feature is activated. From my understanding all three methods should be called every time a user logs
in to SharePoint. I'm using integrated Windows authentication with NTLM.
This is abbreviated code showing only important parts:
public class MyClaimProvider : SPClaimProvider
protected const string MyClaimType = "http://www.mywebsite.ca/identity/claims/parrot";
protected const string StringTypeClaim = "http://www.w3.org/2001/XMLSchema#string";
protected override void FillClaimTypes(List<string> claimTypes)
if (claimTypes == null)
throw new ArgumentNullException("claimTypes");
// add our claim types
claimTypes.Add(MyClaimType);
protected override void FillClaimValueTypes(List<string> claimValueTypes)
if (claimValueTypes == null)
throw new ArgumentNullException("claimValueTypes");
// add our claim value type
claimValueTypes.Add(StringTypeClaim);
protected override void FillClaimsForEntity(Uri context, SPClaim entity, List<SPClaim> claims)
if (entity == null)
throw new ArgumentNullException("entity");
if (claims == null)
throw new ArgumentNullException("claims");
claims.Add(CreateClaim(MyClaimType, "kakadu", StringTypeClaim));
public override bool SupportsEntityInformation
get { return true; }
// ... the rest of code goes here
and this is my feature code:
public class MyClaimProviderRegistrationEventReceiver : SPClaimProviderFeatureReceiver
public override string ClaimProviderAssembly
get { return this.GetType().Assembly.FullName; }
public override string ClaimProviderType
get { return typeof(MyClaimProvider).FullName; }
public override string ClaimProviderDisplayName
get { return "MyClaimProvider"; }
public override string ClaimProviderDescription
get { return "MyClaimProvider desc"; }
public override void FeatureActivated(Microsoft.SharePoint.SPFeatureReceiverProperties properties)
base.FeatureActivated(properties);
var cpm = SPClaimProviderManager.Local;
foreach (var cp in cpm.ClaimProviders)
if (cp.ClaimProviderType == typeof(MyClaimProvider))
cp.IsUsedByDefault = true;
cp.IsEnabled = true;
cpm.Update();
break;
Does anybody know why the methods are not called when a user accesses SharePoint?
Thanks,
Leszek
