34 * structures don't have fields for some of these attributes)

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

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
