This article was previously published under Q183240 SYMPTOMS
If there are multiple SNA Server Host Account Cache databases configured
for use within a Windows NT domain, there may be times when one or more of
the backup Host Account Cache databases are not in sync with the master
database. SNA users or applications (or both) that are configured to use
host security integration features such as single sign-on and host account
synchronization may fail to get host sessions if one of the out-of-sync
backup Host Account databases is accessed for account mapping or
synchronization.
Typical errors that result when this occurs indicate invalid user IDs or
passwords or both. These errors will be returned by the application or
applications (for example, 3270 emulator or APPC/CPIC program) being used.
CAUSE
When a new user account (that did not exist previously in the Windows NT
Account database) is added to the Host Account Cache database, the master
Host Account Cache database sends an update request to all backup Host
Account Cache databases. The backup databases add the same user account to
their copy of the database. This add fails because the backup databases
cannot locate the user account in the Windows NT account database.
WORKAROUND
To work around this problem, you can synchronize the Windows NT Backup
Domain Controller (where the backup Host Account Cache databases are
running) with the Windows NT Primary Domain Controller.
STATUS
Microsoft has confirmed this to be a problem in SNA Server versions 3.0,
3.0 SP1, 3.0 SP2, and 4.0.
This problem was corrected in the latest SNA Server versions 3.0 and 4.0
