PQ60461: USER AUTHENTICATION CREATES TWO CREDENTIALS INSTEAD OF ONE. | |||||||||||||||||||||||||||||||||||||||

|||||||||||||||||||||||||||||||||||||||
![]() APAR status Closed as program error. Error description WebSphere security performs MapCredentials immediately followed by Validate, when a user makes the first request. Both of these calls end up authenticating the same user twice. In particular, the call to getGroupsForUser takes several seconds on each of the two occasions. If we could take away one of these (seemingly redundant) calls (the one made during Validate), this would significantly improve performance for the customer.Local fix an efix has been created for the problem ltp-cred-cache-354.jarProblem summary **************************************************************** * USERS AFFECTED: WebSphere Application Servers users of * * LTPA authentication with custom login. * **************************************************************** * PROBLEM DESCRIPTION: Performance improvement for LTPA * * authentication with custom login or * * Form login * **************************************************************** * RECOMMENDATION: Apply this efix to improve performance for * * Ltpa authentication. * **************************************************************** This is a performance improvement efix. In this efix, we use credential cache technique to reduce the number of LTPA server calls. For custom/Form login with Ltpa authentication, the number of ldap searches are reduced by half.Problem conclusion Unnecessary ldap searches may cause performance problem.Temporary fix The efix PQ58739-354.jar is placed in wasdoc0\Apars\PQ58739\3.5.xComments The efix has been send to client before the APAR was created, so we rename the efix with Apar name.
