the customer wants to know if there is an easy way to restrict (define)
the set of valid characters which are allowed to be used as password.
He does not want to set this in all of his applications which can change
passwords, but to set it in the directory server itself.

Password policy allows you some control over lengths, number of numeric
characters, pasword history, etc.
If you want to do something more, like check passwords against a
dictionary, you can write a server plug-in that can do its own validation
of passwords.
