Server :: Implementing "NT-style" Password Complexity On Samba PDC?
Nov 30, 2009
I would like to ask how could I enforce "NT-style" password complexity, for instance, the new password must contain 2 lowercase characters, 2 digits and 1 non-alphabetic character set, on Samba PDC so that while some samba clients change their passwords from Windows XP workstations. I have configured check password script option on samba configuration file, but users could not change password from Windows XP workstations no matter how complicated password they use.
A dialog box said: The password supplied does not meet the minimum complexity requirements. Please select another password that meets all of the following criteria: is at least 5 characters; has not been used in the previous 0 passwords; does not contain your account or full name; contains at least three of the following four character groups:
English uppercase characters (A through Z);
English lowercase characters (a through z);
Numerals (0 through 9);
Non-alphabetic characters (such as !, $, #, %)

we have a line in /etc/pam.d/system-auth-ac on RH 5.1:
password requisite pam_passwdqc.so min=disabled,disabled,disabled,disabled,8
I believe this should require new passwords to be 4 character classes only with minimum size =8 (uppercase, lowercase, digits, special chars) however running passwd also gives option of using word:word,word which only contains 2 of the required classes. Is there any way to fix this so only 4 character class passwords can be generated ?

I'm having no success getting password complexity to work with RH4/U5. Added/modified the following to /etc/pam.d/system-auth
password required /lib/security/$ISA/pam_passwdqc.so min=disabled,disabled,disabled,disabled,12
password sufficient /lib/security/$ISA/pam_unix.so nullok use_authtok md5 shadow nis remember=24
I have deployed complexity before on other releases w/o problems.This one is a NIS server, but I have other NIS servers working fine. I even tried copying system-auth from a RH4/U2 NIS server which performs complexity to the RH4/U5 system - no luck. When I attempt to change a user password from a user acct, get message that password must be at least 6 characters. The system-auth file I am using dictates 12 characters with 4 different character cases. /etc/login.defs also has minimum length set to 12 - no idea where the 6 character limit is coming from. I also tried using cracklib.so with minlen=12 , no luck there either.

I''m new to Debian 5 so please be gentle
When I use 'adduser' it states 'Enter the new password (minimum of 5, maximum of 8 characters)' - how can I enforce password complexity?
I would like to have a minimum of 10 characters and also have numbers, certain special characters etc.

I must be losing it because I can't seem to find my answer on the google mechine. I need to enforce password complexity in ubuntu. I need min length, upper case, number and or special characters. I don't want to have to install pam_cracklib on all these boxes. I have looked at he common-password and it's not much.

I have NIS setup to manage all my users, and I have samba set up to share out a directory to the users windows computers - which are part of a corporate domain. I have a requirement to synchronise the NIS password to the Samba password so that when a user changes their password in the Linux environment it automatically updates the Samba password so that the user can simply update the password stored by Windows Explorer.

I'm looking for a script which is testing how complex an "added" string is, for example like the user is changing his password and check how complex it is, if it included letters (lower/upper case), numbers and other characters.Im doing this for password check, the user type's the password and must be 6 characters long, have upper case letters lets say and numbers and so on.If anyone knows where I could find some bash script which is doing this, it would be really cool.

I recently switched from centos to fedora as my server choice. Probably not the best decision but I like trying new things. Now before I switched I had my samba server setup just they way I wanted it. Now I'm having a hard time getting it back to that way. Here is my smb.conf
Code:
[global]
workgroup = workgroup
netbios name = netbios name
server string = Linux Server
security = user
wins support = yes
encrypt passwords = Yes
domain logons = yes
[homes]
comment = Home Directories
browseable = yes
writable = yes
valid users = %S
[me]
path = /home/me
read only = no
public = yes
create mask = 0777
directory mask = 0777
browseable = yes
writable = yes
Now I did throw away my old smb.conf because it wasn't that complicated and I figured I could reproduce it.. aside from that everything is working except for the fact that I can access any share I want to listed without it requesting a password. I have a username and password setup with smbpasswd and I think everything else is setup correctly involving samba shares but I have no idea why it won't request a password.

I have set up my samba server. I tested from my windows side, all the public ones works fine except the [homes]. Here is my [homes] setting:
Code:
[homes]
comment = Home Directories
browseable = yes
writable = yes
The homes is suppose to let each user see his/her own home directory. But I tested at the windows side, I found that windows doesn't even prompt me about username or password, it just directly give me "not accessible" error. How do I config so my windows side at least prompt me about username/password?

I setup openldap and samba on 9.10. The ubuntu desktop client gets authenticated successfully with the server.
But when I do a passwd on the client, only the ldap passwd is getting changed but not in the samba and the unix user account.
My smb.conf
Code:
passdb backend = ldapsam:ldap://192.168.3.100
ldap suffix = dc=example,dc=local
ldap user suffix = ou=People
ldap group suffix = ou=Groups

Myself and a friend have our own small IT business; we mainly design and build web sites for other small businesses. One of the things we would like to offer to clients is the ability to relay email addressed to their company's domain to their own personal email address (either web-based, or hosted by their ISP).
Now, clearly there is a risk of our mail relay being marked as "open", and therefore becoming black listed as a source of spam. Not something that we want to happen!setting up such a system? I understand how I would go about configuring an MTA like Postfix or Sendmail to perform such a task, but I'm unsure how I would ensure that relayed mail is delivered and we're not labeled as spammers.
I did wonder if perhaps the "mail forwarding" options in a mail server like Zimbra would get around the issue by forwarding on messages inline or as attachments within new emails (so the messages would appear to be from the account hosted on our server).

I want to use samba for file sharing like on a Windows home network. Actually they are all Linux machines but nfs is too complicated. On my host machine I installed samba and system-config-samba. I created a new share for /home, check marked writable and visible and put access to everybody. For preferences-->server settings--> security the "authentication mode" is set to user, encrypt passwords is no, and guest account is no guest account. Under preferences-->samba users I added myself as a user with the same windows user name as my Linux user name and the same password.
My client is a virtualbox fedora (used for testing purposes but actual clients will be real computers on my home network). I entered the address smb://192.168.1.184. When asked for the user name and password I put my regular user name and password since that was what I set in samba users. However, the password dialog keeps coming up and won't let met into my own computer. If I quit it says something like access is denied. How can I get my home network back? I liked this feature when my home computers ran XP but I switched them to Fedora 12.

I've a java program which needs to be executed regardless of whether a user is logged in or not. Currently I've a shell script which executes the java program. I login to the server and run this shell script when the server is rebooted. I would like to start this script automatically preferably as a service so that I can stop and restart this service whenever I update the java program.

I have an SMB service in my apartment that has all of my media files on it. When I am on Windows and OS X I use iTunes to play my music straight off of my server, no need to copy files over to a local directory. But I have been unable to do this on Kubuntu. Every media player I have used will not add the songs from the server. What iTunes style media player will play songs via an SMB server?

I have to rename a group of machines in my little samba domain (tbd backend) but there is an ugly bug that makes this impossible. have set 'rename user script' variable corectly, also checked all configurations.When i change computer name in my windows box, it shows an error saying something like "Error calling remote procedure"Looking on server side, username for the machine gets correctly changed in /usr/passwd, and also in samba database.But samba log says:

I am looking for tools for static/dynamic code analysis for embedded Linux system development (both device driver and user space apps) with ARM-based processor. We use Eclipse IDE and C++ lanuage for development. Does anybody have recommendation for tools to analyze code complexity? The tools is better to support McCabe complexity metric, however, we may also consider others. Does anybody have recommendation for unit testing?

I've installed a Ubuntu Server 10.04, LAMP configuration,,, nothing extra beside that.
Then I followed this instruction [URL] to set up Samba.
When trying to access the "share" from my windows 7 client, it keeps asking for user and password.
I've been googling around and have found a lot of people having simular problems, but I cant(I think) find any solution relevant for me.
