Problem |
If you use programmatic logins in your security
implementation on WebSphere® Application Server V4.0.1, upgrading to a
newer release of V4.0 might cause unexpected problems. Beginning in
V4.0.2, the security credentials are no longer propagated to every
application thread; this might result in unexpected login prompts that
display during your application's runtime. |

Solution |
The three basic types of logins are:
- prompt logins
- properties logins
- programmatic logins.
Prompt and properties logins are designed to provide an automatic
credential to each thread.
In V4.0.1, the programmatic login incorrectly propagated the
credential to every thread associated with the process. After V4.0.1, the
programmatic login was designed to NOT propagate the credentials to each
application thread associated with the process. The programmatic login
logic can determine whether to set different credentials on each thread,
if necessary.
From a usability standpoint, it is not possible to have such precise
control using a prompt or properties login. |
