[vikas]

Hi team,

For now it seem issue is SOLVED

Samba 4.1.5
Centos 6.3 64bit

Compile using Samba How/To wiki

on windows clients can change password only if the settings are like below

# samba-tool domain passwordsettings show
Password complexity: off
Store plaintext passwords: off
Password history length: 24
Minimum password length: 5
*    Minimum password age (days): 0   # if min age is set to 0 user can 
change password easily*
Maximum password age (days): 42

# samba-tool domain passwordsettings show
Password complexity: off
Store plaintext passwords: off
Password history length: 24
Minimum password length: 5
*    Minimum password age (days): 30   # if min age is set to 30 user 
can cannot change password even using toughest password*
Maximum password age (days): 42

Also like mention before, whether uses is created just now or 24 hrs ago 
it does not matter all can change password if min-age set to 0.
