Details

Description: From the pam_tally man page: "pam_tally has several limitations, which are solved with pam_tally2. For this reason pam_tally is deprecated and will be removed in a future release." pam_tally2 is available on the current system, why is pam_tally still included in /etc/pam.d/system-login by default?

* package version: pambase 20130928-1

I would like to document two points here, in case the FS# gets work:

1. When changing to pam_tally2, it should be considered to add it to
account pam_tally2.so
in the stack as well. Reason: If using sudo to authenticate, the counter for the user will otherwise not be reset on authenticate success - i.e. the user will eventually be locked out no matter what. References: [1] [2]

2. There is a recent (06/2016) bug report on pam upstream, which introduces yet another pam module to replace both pam_tally/pam_tally2.[3] - the bug progress should be checked to avoid changing the stack twice, if [3] eventually gets through.

Ping falconindy, looks like we have a side effect from this in  FS#50369

pambase-20190105.1-1 now uses pam_tally2 with the recommendations here.
