SYMPTOMS
In Microsoft Visual Studio 2005 Team Foundation Server, two users have base-64-encoded security identifiers (SIDs) that are equivalent in case-insensitive comparison. When one of the two users runs a work item tracking query, the query may unexpectedly not return records. If you run the query again, you receive an unhandled exception in Team Explorer.



CAUSE
This issue occurs because Visual Studio 2005 Team Foundation Server uses base-64-encoded SIDs to map security views to user accounts when you run a work item tracking query. Base-64-encoded SIDs are unique if the comparison is case-sensitive. However, base-64-encoded SIDs are not unique if the comparison is case-insensitive. Visual Studio 2005 Team Foundation Server uses a case-insensitive Microsoft SQL Server collation. Therefore, the two users who are mentioned in the &quot;Symptoms&quot; section are mapped to the same security view.
