Which /etc/pam.d/ config file do you need ?

Hi,

from the logs below it looks like you are using ssh to log in, so it
would be /etc/pam.d/sshd and all the files which might be referenced in
that file.

bye,
Sumit

 Hi, thank you for the quick reply.
 
 We were further investigating the issue.
 
 We were testing with user "usu5" that has its password expired. The log of IdM server below shows that Samba AD DC is sending "Password has expired" for user "usu5", thats OK.
 So we can suspect that IdM is not behaving as expected, it should prompt a password expiry to the user and let the user change it, but something is wrong with our config or scenario because that does not happen.
 
 Feb 23 08:14:35 idmsrvpru.idmpru.fnr.gub.uy krb5_child[4283]: Password has expired
 Feb 23 08:14:35 idmsrvpru.idmpru.fnr.gub.uy krb5_child[4283]: KDC reply did not match expectations
 Feb 23 08:14:35 idmsrvpru.idmpru.fnr.gub.uy sshd[4281]: pam_sss(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=10.9.9.8 user=usu5@adtest.fnr.gub.uy
 Feb 23 08:14:35 idmsrvpru.idmpru.fnr.gub.uy sshd[4281]: pam_sss(sshd:auth): received for user usu5@adtest.fnr.gub.uy: 4 (System error)
 Feb 23 08:14:37 idmsrvpru.idmpru.fnr.gub.uy sshd[4277]: error: PAM: Authentication failure for usu5@adtest.fnr.gub.uy from 10.9.9.8
 
 Also in the attached file there is the log of sssd_idmpru.fnr.gub.uy.log that shows a login attempt with user "usu6", that is on the same situation as "usu5".
 
 ############
 
 We have done other tests as well, in this case we are logged on IdM server as user "usu1", which has a password not expired and working properly. But when we try to change it with "passwd" it also fails.
 
 [usu1@adtest.fnr.gub.uy@idmsrvpru /]$ passwd
 Changing password for user usu1@adtest.fnr.gub.uy.
 Current Password:
 Password change failed. Server message: Old password not accepted.
 passwd: Authentication token manipulation error
 
 Log of this test on IdM server:
 
 Feb 23 08:15:40 idmsrvpru.idmpru.fnr.gub.uy passwd[4335]: pam_unix(passwd:chauthtok): user "usu1@adtest.fnr.gub.uy" does not exist in /etc/passwd
 Feb 23 08:15:45 idmsrvpru.idmpru.fnr.gub.uy passwd[4335]: pam_sss(passwd:chauthtok): User info message: Password change failed. Server message: Old password not accepted.
 Feb 23 08:15:45 idmsrvpru.idmpru.fnr.gub.uy passwd[4335]: pam_sss(passwd:chauthtok): Authentication failed for user usu1@adtest.fnr.gub.uy: 4 (System error)
 
 Which pam logs do u need ? we have several files apparently.
 
 
 Thank you guys again and best regards.

 Hi,
 
 We currently have an IdM installation with a trust relationship with a
 Samba AD DC. Our user accounts reside on Samba AD DC, we dont have user
 accounts on IdM. We are having a problem with Samba user acounts that
 have its passwords expired.
 
 When we try to login with an ubuntu IdM client with one of those
 accounts, it fails and asks again for password. The behaviour we are
 expecting is that Ubuntu should ask for a password change.
 
 
 
 I think you need to look at SSSD troubleshooting guide and investigate a
 bit yourself. Without logs it is impossible to tell what's wrong.
 
 Please see https://sssd.io/troubleshooting/basics.html and
 https://sssd.io/troubleshooting/ipa_provider.html for two parts that
 would be relevant here.
