The password MUST:

Contain eight characters or more
Contain characters from two of the following three character classes:
Alphabetic (e.g., a-z, A-Z)
Numeric (i.e. 0-9)
Punctuation and other characters (e.g., !@#$%^&*()_+|~-=\`{}[]:";'<>?,./)
The password MUST NOT be:

A derivative of the username
A word found in a dictionary (English or foreign)

Please friends for this what changes i have to do in my server.
Thanks in advance....
