APAR status
Closed as program error.
Error description
I have installed the fix 5.0.2.1 on two PCs (one windows and one
linux)
and verified the installation with "versionInfo"
Name IBM WebSphere Application Server
Version 5.0.2.1
ID BASE
Build-Version cf10337.06
Build-Datum 09/20/2003
But when I run my demo LoginTest-Client (which I have already
sent to you) the behavior is identical to the one described
earlier:
When using a ProviderUrl with a list of cluster servers of which
the first one is down, the InitialContext lookup will succeed
but the login will fail.
Since the description of
PQ76786 sounds very similar to our
problem, I also tried the following:
1. InitialContext and lookup("") with ProviderUrl pointing ONLY
to server that is down. --> failure (as expected)
2. LoginContext and login attempt --> failure (as expected)
3. InitialContext and lookup("") with ProviderUrl pointing ONLY
to server that is up and running --> success
4. LoginContext and login attempt --> still failure !!!
Although
PQ76786 and our problem sound related they apparently
are not the same.
Local fix Problem summary
****************************************************************
* USERS AFFECTED: WebSphere Application server implementing *
* JAAS login logic. *
****************************************************************
* PROBLEM DESCRIPTION: JAAS login does not have failover *
* functionality. *
****************************************************************
* RECOMMENDATION: *
****************************************************************
Logins always use the first server in a list. If first server
fails, there is no attempt to failover to another server.
Problem conclusion
JAAS login failover capability was added. If multiple security
servers are configured by Context.PROVIDER_URL, logins will
automatically failover to severs in the order specified.
Failover function can also be configured by the following
properties in the sas.client.props.
