Things that you can't find in 'man smb.conf' or the SWAT help (the same)
usually aren't available. Sometimes they are, but undocumented.

In this case, this is policy and a Windows thing. As far as XP goes, one

HOWEVER. A German firm has produced the Nitrobit Group Policy Editor
which, for a fee (license per workstation, for schools at least, is dead

It doesn't have any other means of storing extended (Windows) password
parameters (min. length, complexity etc.).

As far as LDAP goes, it gives the possibility od adding attributes in
the passwordPolicy objectclass from ns-pwd-policy.schema. But similar

How does one set the attributes that are already  available in the
ldapsam backend?
