Impossible. winbind certainly knows all about writing to LDAP otherwise 
it won't be a backend database for rid maps and especially for 
maintaining the same rids across boxes (okay, this got solved at a 
higher level and thus an ldap backend is not needed for maintaining 
identical rids across boxes) and I cannot imagine how that would be 
accomplished without knowing anything about writing to ldap.

??? What's that? ???
