Re: Password policy not working

["Nick W. Harrison" <nwharrison@xxxxxxxxxxxxxxxxx>]

Aside from any default policies, I created a password policy for the subtree on ou=People,dc=example,dc=org. The enabled settings in that policy are:

 

·         Fine-grained subtree policy enabled

·         Password expires after x days

·         Check password syntax (followed by the specifications for that)

 

The “User may change password” option is left unchecked in this password policy.

 

I don’t have a user password policy enabled….only subtree. I have my user objects and password being synced over from AD via a unidirectional relationship (win-to-linux).

The below snippet appears to be the full sequence from the access log on my LDAP server. I have a Linux client using SSSD to bind to the directory (account: mybindacct). I SSH into my client as johndoe and change my password with the usual passwd command.

One question is which account is actually doing the attribute change: is it my SSSD bind account the one updating the johndoe password attribute on behalf of the johndoe user?

It should be changing it as "uid=johndoe,ou=test,ou=people,dc=example,dc=org", but perhaps the password modify extended operation is bypassing the password policy?  I need to try and reproduce this before opening a ticket.  So the global password policy under cn=config allows users to change their password, but a subtree policy denies the user this privilege but they are still allowed to reset their own password, is this correct?  I need to make sure I am using the same setup as you are.

Thanks,

Nick

That is the wrong package "389-ds", what is the version of "389-ds-base"? 

Can you share what is in the server's access log when the password is changed (/var/log/dirsrv/slapd-YOUR_INSTACE/access)?  There should be a few operations that occur during the password change so please make sure to provide a full clip from the log.

Thanks,

Mark

Hello –

 

I have a password policy on the OU that contains all of my user accounts. This password policy is set on the subtree and the “user may change password” option is deselected. However, I’m still able to change my password if I use passwd on a LDAP client.

 

I’m running an older version of 389-ds…v.1.2.2-6…and am wondering if there is anything additional I need to put in place to prevent users from changing their passwords. My accounts and passwords are replicated over from AD with a unidirectional relationship, and the clients are doing simple binds.

 

Thanks for any thoughts.
