Error Message: NetWare Authentication Failure

• Microsoft Windows NT Workstation version 4.0
• Microsoft Windows NT Server version 4.0

SYMPTOMS

When you attempt to log on to a Novell NetWare server using Client Services for NetWare (CSNW), you may receive the following error message:

NetWare Authentication Failure

You cannot be authenticated on <server> due to the following reason:
A connection to the server could not be made because the limit on the
number of concurrent connections for this account has been reached.

Do you want to select another preferred server?

CAUSE

This behavior can occur if you log in to a computer that has remote access service (RAS) Autodial Manager service enabled, log out of Windows NT, and then immediately log back in without restarting the computer.

RESOLUTION

To work around this issue, disable the RAS Autodial Manager service. To do this, follow these steps:

1. Click Start, point to Settings, click Control Panel, and then double-click Services.



2. Click Remote Access Autodial Manager, and then click Startup.



3. Click Disabled, click OK, and then click Close.

1. Click Start, point to Settings, click Control Panel, and then double-click Services.



2. Click Remote Access Autodial Manager, and then click HW Profiles.



3. Click the appropriate profile, and then click Disable.



4. Click OK, and then click Close.

MORE INFORMATION

This issue occurs when the previous preferred server connection is not closed because the Logon User ID (LUID) for the previous user is not released when the user logs off. This can occur when the RAS Autodial Manager service impersonates the user and uses the LUID.

The previous logon is not released because its LUID has a reference counter that is incremented when the user's credentials are impersonated (used) and decremented when the impersonation is released.

When the reference count for an LUID reaches 0, the kernel notifies the Local Security Authority (LSA) that the user has logged out. The LSA then notifies CSNW to disconnect the user's preferred connection to the Novell NetWare server. When the RAS Autodial Manager is enabled, the LUID for the user that is currently logged in is not decremented to 0. Therefore, the LSA is not notified when the user logs out.
