32 * Other LDAP based login attributes: accountExpires, etc.
33 * (should be the domain of Samba proper, but the sam_password/struct samu
34 * structures don't have fields for some of these attributes)
36 * SSL is done, but can't get the certificate based authentication to work
37 * against on my test platform (Linux 2.4, OpenLDAP 2.x)
40 /* NOTE: this will NOT work against an Active Directory server
41 * due to the fact that the two password fields cannot be retrieved
42 * from a server; recommend using security = domain in this situation

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