Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server * * and the OIDC * **************************************************************** * PROBLEM DESCRIPTION: The OIDC TAI does not remove OAuth * * access * * token tries from the SessionData * * cache. * **************************************************************** * RECOMMENDATION: Install a fix pack or interim fix that * * contains * * this APAR. * **************************************************************** The OIDC TAI stores information about access tokens that are obtained using the com.ibm.websphere.security.oidc.util.OauthClientHelper API in the SessionData cache. These OAuth access tokens can fill up the cache.
Problem conclusion
When an access token is obtained with the API, a lifetime is not set on the SessionData object. Therefore, the SessionData object does not time out. The OIDC runtime is updated to set the lifetime of a SessionData object when an access token is obtained with an API. The lifeti will either be the lifetime of the access token, or the value th is hardcoded in the OIDC TAI configuration by the administrator. The fix for this APAR is targeted for inclusion in fix pack 8.5.5.21 and 9.0.5.11.
