[Samba] swat per user cant change samba password

[Terry]

I need samba users to be able to change there own password I have swat running I can login as root and changes users passwords fine. But if I login into swat as a normal user and try to change a password I get

machine 127.0.0.1 rejected the password change: Error was : Password restriction.

The passwd for 'username' has NOT been changed. 

If I try it from the shell I also get

samba# su user
%smbpasswd
Old SMB password:
New SMB password:
Retype new SMB password:
machine 127.0.0.1 rejected the password change: Error was : Password restriction.
Failed to change password for user

Is there a default setting in place restricting none root users from changing there passwords ?

samba-3.0.37,1

samba# testparm

        vfs objects = recycle
        recycle:exclude = *.tmp, *.bak
        recycle:keeptree = yes
        recycle:repository = RecycleBin
        recycle:touch = True
