Specifies a map of permitted login hours per day. The value is an array of bits, one per hour starting at 0000 Sun UTC, 24 bits per day, 7 days. It is not an ASCII array, but an array of binary bytes. The format is exactly compatible with the LoginHours user attribute in Microsoft Active Directory, and can therefore be used when accessing Active Directory via LDAP:

<AuthBy LDAP2>
      Host uniform
      AuthDN cn=Administrator,cn=Users,dc=open,dc=com,dc=au
      AuthPasswordadmin
      BaseDN ou=csx users,dc=open,dc=com,dc=au
      ServerChecksPassword
      UsernameAttr sAMAccountName
      AuthAttrDef logonHours,MS-Login-Hours,check
</AuthBy>
