28 * however, using only one within Samba would be nice

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)

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
