Thank you for you answear, but I try what you say and it dosen't work.
I now using obey pam restrictions, I restart samba... and this is my pam
config:
bowman:/var/log# cat /etc/pam.d/samba

obey pam restrictions = Yes
But when I try to change the password, I can use my old one still. I can
use a password withouth the two digits... like nothing.
Are you sure that with ldap the obey pam restrictions works?
Thanks in advance... Sorry for my english.

Hi Guido,
There are a set of ways to accomplish such task.
Some I use is:
1) Set obey pam restrictions = yes in the smb.conf file.
2) Set check password script = /usr/sbin/crackcheck -d
/usr/lib/cracklib_dict
This check the user password against a dictionary. Crackcheck can be
downloaded from samba
(http://people.samba.org/bzr/mwxia/samba-soc/examples/auth/crackcheck/).
The cracklib package must be installed for the dictionary to work.
3) Use pam pam_cracklib to set your password rules for lower/upper
characters, numbers, special characters, etc:
password requisite /lib/security/$ISA/pam_cracklib.so retry=3
minlen=8 difok=3 dcredit=-1 lcredit=-1
Or pam_passwdqc for the same thing:
password requisite /lib/security/$ISA/pam_passwdqc.so
min=disable,8,8,8,8 max=25 passphrase=0 match=6 similar=deny random=64
enforce=users retry=3
See the man pages for correct options values.
4) You can block users after X retries using pam pam_tally.so, but I
haven't tried this yet.
I think this can help you.

Maybe I can do this with the "check password script". But I only found
the cracklib example. Anyone knows a way of doing this? Becouse the
cracklib example only check agains a dictionary.
Tnxs in advance.
