We are testing a new passwd syntax policy in ldap we have only cfg password length to 8 char and according to this RH Doc bellow there are some exceptions( aka "trivial words" and uid, cn, givenName which can not be used ) when a user tries to update his passwd , for example if the new passwd contains more than 3 char from his uid the ldapasswd cmd will fail .
For new Passwd :cheese671cheese >> will fail
But for passwd: cheese67cheese will work .
This is the "token length" are you hitting. So there are defaults to some password policy attributes, even if you don't explicitly set them. So "PasswordMinTokenLength" defaults to 3 characters, that's why cheese671cheese is rejected and cheese67cheese is not.
See our docs for all the password policy attributes and their default values:
start there and scroll down to see most of the password policy attributes, their meanings, and default values.
I need to understand if we need other passwd attributes to cfg or why this char min limitation and how to solve this issue?
Our uid can be from 4 char lenhgt to 14 char length.
Here is in ldap ldif:
And RH DS doc :
188.8.131.52. Password Syntax Checking
Password syntax checking enforces rules for password strings, so that any password has to meet or exceed certain criteria. All password syntax checking can be applied globally, per subtree, or per user. Password syntax checking is set in the passwordCheckSyntax attribute.
The default password syntax requires a minimum password length of eight characters and that no trivial words are used in the password. A trivial word is any value stored in the uid, cn, sn, givenName, ou, or mailattributes of the user's entry.
