SNA Server EHNAPPC Security fails using 10 Character User ID

ID: Q140423

The information in this article applies to:

Microsoft SNA Server, versions 2.0, 2.1, 2.11
on the following platforms: NT

SYMPTOMS

When you use SNA Server client and IBM CA/400 (V3R1), you are prompted to enter a User ID and password. If your user ID has nine or less characters, you are able to log on. If your user ID has ten characters, the following error appears:

SNA Server EHNAPPC Security
7003 Cannot assign a network drive

If you choose OK, the user ID and password prompt appears again. This time only the first nine characters of the user ID appear in the User ID box.

CAUSE

The SNA Server Win 3.x EHNAPPC interface does not properly handle AS/400 signon if the AS/400 userid is ten characters in length. The tenth character is truncated.

RESOLUTION

Microsoft has updated the following files to correct this problem (on Windows 3.1x clients):

<winroot>\SYSTEM\EHNAPPC.DLL
<winroot>\SYSTEM\EHNRTRW.DLL

STATUS

Microsoft has confirmed this to be a problem in SNA Server for Windows NT. This problem was corrected in the latest SNA Server for Windows NT, 2.11 U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
