Security :: Password Complexity With Pam_passwdqc.so?
Mar 25, 2009we 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 ?
Security :: Enforcing Password Complexity In Ubuntu?
Apr 9, 2010I 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.

Red Hat :: Password Complexity Not Working On RH4 Update 5?
Apr 30, 2009I'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.

Server :: Implementing "NT-style" Password Complexity On Samba PDC?
Nov 30, 2009I 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 !, $, #, %)

Mar 1, 2011I have got a RHEL 5.6 server configured to authenticate via a Windows 2008 domain controller via LDAPS.Everything is working fine, except from the following: When I create a new user in Active directory and check the option "user must change password at next logon", the new user cannot logon and gets an "access denied" message. In /var/log/secure, I find the following:

As soon as I uncheck the "user must change ..." option, the user can log on without problems. Also password change via the passwd command works.

View 6 Replies View RelatedFedora Security :: Use A Passphrase - Not A Password
Feb 9, 2010Simply, the number of possible combinations of passwords increases as an exponent of the number of characters used and as a factor of the number of characters available for use.
26 potential characters for a 2 character password results in 26^2 possible password combinations. This means that each new character added would result in an "order of magnitude" increase in the difficulty of brute force attack.
Using a phrase, complete with punctuation and capitalization is the very best mnemonic device to remember a password. Consider this, how hard is it to remember; The quick brown fox jumped over the lazy dog.
Than it is to remember, l33tsp34kp@ssw0rd
If we pretend that both of these passphrases are generated from a character set consisting of 26 characters, the first would be one of a possible 15274273784216769021564085930704478424313742483024 510976. The second would be one of a possible 1133827315385150725554176.
In short, use a passphrase not a password, they are much MUCH more secure.

Jul 30, 2009I got during my last year of high school, and I recently installed Fedora 11. During the installation, I misunderstood one of the questions, and set my root password as what I wanted my account password. I want to go in and change it, because it's pretty easy to figure out and has me feeling really vulnerable, but it won't let me. I went to System-Administration-Root Password, entered my password, and put in a new one, but it won't let me click Change Root Password. The button is faded out and unclickable. I've tried several different passwords, and triple-checked each to make sure I typed it in correctly, but it won't work.
