Re: [Freeipa-users] IPA 3.0 RHEL 6.4
Hello Dmitri, We are currently using Samba as a file server and a DC with NT style domain for our Windows clients. IPA is the password backend for Samba. Our Red Hat consultant originally had the following items working when this system was installed last year. ** Ability to add groups in the IPA web interface for samba I have these patches and need to make sure that they work with IPA 3.0 and RHEL 6.4 before I apply them. ** We have a default password policy of 90 days expiration. This policy also has complexity, history, length, etc. Early this year that 90 day expiration stopped working and my Windows users were no longer receiving a must change password notice. We were hoping the update to RHEL 6.4 and IPA 3.0 would fix this but it has not. Currently my users are showing an EXPIRATION in IPA of June/July or so time frame. Back in April we manually changed all user's passwords to a temporary. That prompted them to login and change their password, hoping this would kickstart the 90 day expiration again. That was NOT successful. At a MINIMUM we are needing to correctly have IPA expire a user's password and allow Samba to understand that as well based on the password policy IPA shows for a given user. I have a test user who has a 2nd password policy we created. That users has 1 day expiration within IPA. When I change the following value using ldapmodify, It CORRECTLY makes Samba prompt the user to change their password when logging in the next time. When I change this test password, IPA reset's the EXPIRATION DATE to 90 days out and not 1 day from the time password was changed. --- A third item we need fixed if possible, is the ability to enforce password complexity, history, length, etc. through Samba based on what IPA shows for a user's password policy. I cannot confirm if this WAS working or not after it was initially installed. I guess you or Rob would be the individuals who could tell me what is possible to enable this feature.

Red Hat is unable to confirm these patches are updated for IPA 3.0 RHEL 6.4 even though their Red Hat consultant created these a year ago. I'm not clear what you mean by updated for IPA 3.0. Are you asking the patches to be rebased? It is also unclear if things were working properly with 2.2.0 and broke with 3.0, or if these things never worked, or something else. ** IPA password policy (history, length, complexity, etc.) enforcement Our current versions are not allowing the IPA password policy to work with Samba. My Windows users are able to change their password either MANUALLY or WHEN FORCED to reset via the IPA interface. However, non of the password history, length, complexity and so on are enforced with Samba and users are able to either keep the same password or change it to anything they want without restrictions. Can you be more specific about where the password changes are happening? What do mean by manually? Changing it via the UI should apply password policy because that is really independent of any Samba changes that have been made. ** Samba password change also changing correctly the IPA expiration date so IPA can successfully reset the (sambaPwdLastSet: 0) value upon 90 days since last password change If we manually run ldapmodify and change the value of sambaPwdLastSet to equal 0, this correctly forces the end user to change their password in Windows. The issue though is their IPA password expiration date listed in the interface isn't correctly showing the amount of days to expire NEXT. I have a test user that has a password policy of 1 day expiration. I would expect this user to show an expiration date of the next day after password change but for some reason it always keeps showing about 90 days out, which is my default policy for all users. I need to be able to test that IPA is correctly expiring the password after 1 day so that I know in 90 days my other users will receive the same expiration. For most of this year password expiration was not working and IPA is showing a password expiration of months ago when their password should have expired (samba never prompted for this change). Since we updated to IPA 3.0, I'm hoping that when I reset their sambaPwdLastSet to 0 that IPA will start enforcing a 90 day expiration again. I don't really know much about how Windows/Samba does password expiration, but IPA has no process to look at the last set date, compare that to the policy, and reset sambaPwdLastSet. Is that what you're expecting? Any help you can provide on these issues would be greatly appreciated! Also, what would you recommend for future IPA versions and
Re: [Freeipa-users] IPA 3.0 RHEL 6.4
Hi Loris,
Thanks for the quick and informational response.
I'm going to ask for a little hand holding here. I'm not well versed in
LDAP or IPA.
How would I use ldapsearch to check that this value is correctly
set already? I have already set ldap passwd sync = only in smb.conf as
recommended by our Red Hat Consultant.
Where can I find that patch that is needed to correctly set the
sambaPwdLastSet attribute?
To have some correspondence between IPA password policies and samba
password policies you need to:
1. Create a sufficiently privileged bind user in ipa and have
samba connect to IPA using that bind user. For example
uid=sambaadmin,cn=sysaccounts,cn=etc,dc=example,dc=com
2. To have password changes in windows work as normal user password
changes (instead of password resets) you must add the above
bind user to the passsyncmanagersdn attribute of the
ipa_pwd_extop plugin configuration. Similar to what is explained
here:
http://www.freeipa.org/docs/1.2/Installation_Deployment_Guide/en-US/html/sect-Installation_and_Deployment_Guide-Setting_up_Synchronization_Between_IPA_and_Active_Directory-Setting_up_Windows_Sync_on_the_IPA_Server.html
3. Samba should not mess with password expiration attributes in
ldap, so you should set ldap passwd sync = only in smb.conf
4. You need a small patch in the ipa_pwd_extop plugin to have it
set the sambaPwdLastSet attributes on password changes
5. Samba password policies (Maximum password duration, minimum
password duration) should match the IPA password policies
Below are the patches I received from our Red Hat consultant.
Is this similar to what your talking about?
