selfttest for user password change

User on Windows 7 Client can not change his own password.
samba-tool user password -Uuser%verYc0mpleXPW --newpassword="newverYc0mpleXPW" does the same.

ERROR: Failed to change password : samr_ChangePasswordUser3 for 'SAMBADOMAIN\\sambatool1' failed: NT_STATUS_PASSWORD_RESTRICTION

I attached a patch for the samba_tool selftest which triggers the problem.
Wasn't able to test the patch, since password changes do not work atm ;-)

Comment 1 Matthias Dieter Wallnöfer 2012-04-06 12:35:48 UTC 
That is not a real bug: look at "samdb_check_password()" - "check_password_quality()" seems not to be satisfied.
Comment 2 Matthias Dieter Wallnöfer 2012-04-06 12:40:09 UTC 
Or there is also the minimum password age which has to be satisfied ecc...
Please try to disable the various password complexity settings - the password changes should work then.
Comment 3 Björn Baumbach 2012-04-06 13:52:55 UTC 
You are right! Sorry for confusion.
It is the minimum password age, with the default value of one day.

But some weeks ago (I'm nearly sure) I was able to change the user password with the default password settings several times (without waiting one day ;-) ).
