33 * Other LDAP based login attributes: accountExpires, etc.
34 * (should be the domain of Samba proper, but the sam_password/struct samu
35 * structures don't have fields for some of these attributes)
37 * SSL is done, but can't get the certificate based authentication to work

42 * due to the fact that the two password fields cannot be retrieved
43 * from a server; recommend using security = domain in this situation

56 * Work around versions of the LDAP client libs that don't have the OIDs
57 * defined, or have them defined under the old name.
58 * This functionality is really a factor of the server, not the client
