DOCUMENT:Q222109 23-OCT-2000 [sna] TITLE :Using Persistent Verification, Blank Password Not Sent To Host PRODUCT :Microsoft SNA Server PROD/VER:WINDOWS:4.0,4.0SP1,4.0SP2 OPER/SYS: KEYWORDS:kbsna300sp4fix kbsna400sp3fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server, versions 4.0, 4.0SP1, 4.0SP2 ------------------------------------------------------------------------------- SYMPTOMS ======== If the host indicates support for persistent verification in the LU6.2 BIND command, and an APPC or CPIC application attempts to allocate a conversation with the password set to spaces (blank), no security vectors are sent in the FMH-5 attach request. This could cause the host to reject the FMH-5 attach request with the following sense code: 080F6051 = Access Security Information Invalid Note that this sense code is normal if an invalid user ID or password is provided to the host. However, in this special case (where persistent verification is being used), the SNA Server APPC DLL (Wappc32.dll) fails to send any security information to the host (for example, the user ID or password). RESOLUTION ========== SNA Server 4.0 -------------- To resolve this problem, obtain the latest service pack for SNA Server version 4.0. For additional information, please see the following article in the Microsoft Knowledge Base: Q215838 How to Obtain the Latest SNA Server Version 4.0 Service Pack SNA Server 3.0 -------------- To resolve this problem, obtain the latest service pack for SNA Server version 3.0. For additional information, please see the following article in the Microsoft Knowledge Base: Q184307 How to Obtain the Latest SNA Server Version 3.0 Service Pack STATUS ====== Microsoft has confirmed this to be a problem in SNA Server versions 3.0 and 4.0. This problem was first corrected in SNA Server version 3.0 Service Pack 4 and SNA Server version 4.0 Service Pack 3.
