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.
