Hello the list,

As a workaround for another issue we have with using two-factor authentication, we’re using pam_krb5 to change expired passwords, so in /etc/pam.d/password-auth-ac whe have changed the password section to be:

password    requisite     pam_pwquality.so try_first_pass local_users_only retry=3 authtok_type=

password    sufficient    pam_unix.so sha512 shadow try_first_pass use_authtok

#password    sufficient    pam_sss.so use_authtok

password    sufficient    pam_krb5.so chpw_prompt=true use_authok banner=Retype

This puts the user through a password reset process without the second factor interfering, but at the end they get shell. This is without the second factor.

Is there a parameter this so that the connection is disconnected instead, or the connection attempt is restarted?

I’ve also tried changing the pam control ‘sufficient’ from:

[success=done new_authtok_reqd=done default=ignore]

To

[default=ignore]

Regards,
