Error description
This defect is to document two sets of changes that both improve the performance of user lookups as well as the performance of the MemberFixer utility. The first set of changes is to optimize WCM's user lookup logic to: (A) Remove 2 redundant PUMA calls when fetching users via DN (B) Better leverage the User cache (when activated) to avoid going to PUMA at all when fetching users The second set of changes is to add two new options to the MemberFixer that can improve performance in some scenarios, they are: (1) A new 'useUserCache' option that will utilise the WCM User cache throughout the utility execution to avoid repeated lookups for the same user - but requires the utility to flush that cache at utility initialization to ensure that only the latest data is available (for large repositories this will have a net gain in performance). Defaults to false. (2) A new 'treatAllUsersAsMissing' option that allows the end user to indicate to WCM that all users won't exist in the current repository and thus non-existant handling should take place - useful when an LDAP change takes place that will invalidate 'every' user entry, but can also be dangerous (especially if the invalidDN option is used). Only use with care and backup repository first. Defaults to false. Opened for release 6106
