I noticed Samba 3 can be built to support "ACL"s, so I tried it, mounted a ufs2 partition with acls, shared it and really, manipulation of files through windows explorer dialog adds ACL data to files, and getfacl(1) reports there indeed are ACLs. BUT, there are two problems: the permissions set this way are weird when viewed from ls or getfacl (looks to me like random r/w/x bits are set in the unix perms mask), and using it on windows "roaming profiles" share causes the windows client to fail on logoff, complaining it cannot create/store some roaming profile folders (but some files and folders work ok). Did I misunderstood what Samba's ACL support means, or is it a bug? Did anybody succeed running Samba with acls-enabled filesystem?
