SYMPTOMS

A hotfix rollup package is available for the Microsoft .NET Framework 3.5 Service Pack 1 (SP1). This rollup package resolves the following issues in the Active Directory Web Service (ADWS).

Issue 1

You locate a domain controller to run one of the following operations in the custom action protocol:

GetADPrincipalGroupMembership
GetADGroupMember
GetADPrincipalAuthorizationGroup

After you run one of these operations several times, the domain controller becomes unresponsive.

Issue 2

When you run an ADWS service that uses the GetADPrincipalGroupMembership operation in the custom action protocol, the service crashes.

Issue 3

You cannot use the GroupPrincipal.GetMembers method to return any of the following group objects:

Domain controllers
Read-only domain controllers
Domain computers

Issue 4

You are using the Active Directory Lightweight Directory Services (AD LDS) mode. You have a group that contains members from different partitions. If you call the GroupPrincipal.GetMembers method, an exception occurs, and you receive the following error message:

Microsoft.ActiveDirectory.Management.ADException: Unknown error (0x5011) ---> System.ServiceModel.FaultException`1[System.ServiceModel.ExceptionDetail]: Unknown error (0x5011) (Fault Detail

at System.ServiceModel.Dispatcher.SyncMethodInvoker.Invoke(Object instance, Object[] inputs,
Object[]& outputs)
at System.Se...).

Issue 5

You are using the AD LDS mode. You have a .NET Framework application that uses the User.GetGroups method. However, the method returns an empty set.

Issue 6

The UserPrincipal.GetGroups method returns cross-domain local groups for a member. For example, consider the following scenario:

A target domain and a foreign domain are located in the same forest.
A user inside the target domain is a member of a local group in the foreign domain.
A global catalog server is available in the foreign domain, but no global catalog server is available in the target domain.

When you run the GetADPrincipalGroupMembership method in this scenario, the local group in the foreign domain is returned.

Notes

In this scenario, this issue may also occur when the global catalog servers are available in both domains.
This issue occurs if certain site settings are specified on the available global catalog servers.

Issue 7

The information about visited members is cached unnecessarily.

Issue 8

When an AD LDS account is a member of more than 1500 groups, the GetGroups method does not return all the groups.

CAUSE

The following causes match the first three issues that are described in the "Symptoms" section:

Cause of Issue 1

This problem occurs because, when you use Impersonation, a handle leak occurs in the GetGroups, GetMembers, and GetAuthorizationGroups methods.

Cause of Issue 2

This problem occurs because multiple threads call the UserPrincipal.GetGroups method at the same time. When a static object is shared by the threads, and two threads try to free the same memory block, an access violation occurs.

Cause of Issue 3

This problem occurs because the filter that is used to fetch the objects includes only the user object category.
