.sid_uri(sid) ⇒ Object

This method should only be used to generate WinNT://<SID> style monikers used for IAdsGroup::Add / IAdsGroup::Remove. These URIs are not useable to resolve an account with WIN32OLE.connect

.sid_uri_safe(sid) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

This method should only be used to generate WinNT://<SID> style monikers used for IAdsGroup::Add / IAdsGroup::Remove. These URIs are not usable to resolve an account with WIN32OLE.connect Valid input is a SID::Principal, S-X-X style SID string or any valid account name with or without domain prefix
