This file wraps all differing system ACL interfaces into a consistent
one based on the POSIX interface. It also returns the correct errors
for older UNIX systems that don't support ACLs.
The interfaces that each ACL implementation must support are as follows :

int sys_acl_get_tag_type( SMB_ACL_ENTRY_T entry_d, SMB_ACL_TAG_T *tag_type_p)
