allow installation in a domain that uses xACL

If you try to install Sametime 11.6 on a server in a domain that uses xACL, you will not be able to do it. This is a known issue (https://support.hcltechsw.com/csm/en?sys_kb_id=c602ac241b6df30083cb86e9cd4bcb2f&id=kb_article_view&sysparm_rank=1&sysparm_tsqueryId=f129c555dbd86c50a45ad9fcd39619a3), but the provided solution (disable xACL, install Sametime, re-enable xACL) is not feasible. If you disable xACL you will lose forever the settings and have to recreate them manually one by one when re-enabling it. (https://help.hcltechsw.com/domino/10.0.1/conf_disablingextendedaccess_c.html) "Disabling extended access removes all evidence of extended ACL settings, information that cannot be recovered unless you restore it from a recent backup or archive of the directory, or unless you write down the settings prior to disabling them and then reapply them manually later."
