Bug #: 472 (SQL Hotfix)



Microsoft distributes Microsoft SQL Server 2005 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 fix release.



SUMMARY
This article describes the following about this hotfix release:
 * The issues that are fixed by the hotfix package
 * The prerequisites for installing the hotfix package
 * Whether you must restart the computer after you install the hotfix package
 * Whether the hotfix package is replaced by any other hotfix package
 * Whether you must make any registry changes
 * The files that are contained in the hotfix package



SYMPTOMS
Consider the following scenario:  In Microsoft SQL Server 2005 Analysis Services, you create two user accounts. The two user accounts are members of the same role.  The role uses dynamic dimension security. For example, you enable dynamic dimension security for the role by setting the following Multidimensional Expressions (MDX) statement for the role. Filter([Organization].[Organization Name].Members, ( STRTOTUPLE(&quot;[Employee].[Login ID].[&quot; + MID( USERNAME, INSTR(1,  USERNAME, &quot;\&quot;) + 1, 128 )+ &quot;]&quot;), [Measures].[Access Indicator]) = 0)  The two user accounts have different permissions to view the members of a dimension hierarchy. A user uses one of the user accounts to start SQL Server Management Studio and to connect to the instance of Analysis Services. Then, a second user uses the second user account to start SQL Server Management Studio and to connect to the instance of Analysis Services.

In this scenario, the first user can correctly view the members that the first user account has permission to view. However, the second user can view only the same members that the first user can view. The second user can view these members even though the second user account does not have the permission that is required to view these members.

<div class="cause_section">

CAUSE
This problem occurs because the dynamic dimension security data is cached when the first user connects to the instance of Analysis Services. When other users connect after the first user connects, the connection uses the cache to set the permissions for the later users.
