Option to keep LDAP users and groups inside the cwd_user and cwd_group table although the users or groups could not be found during the directory synchronisation.

Crowd users often lost their local group membership due to the ongoing bug CWD-4849 if the directory sync is unable to find the users, but the users reappear in the subsequent synchronisation.

Therefore, it would be useful to have an option inside the User Directory Connector Configuration to keep LDAP users and groups inside the cwd_user and cwd_group table although the users or groups could not be found during the directory synchronisation.
