After adding to /etc/pam.d/common-auth file like this:

auth    required
auth    required
auth    required onerr=fail deny=6

After each successful login, the failed login count is incremented.  After the number of successful logins matches the maximum failed login count the account is locked and the account has to be manually reset.

The user logs in successfully.

user1@server:~> ssh geeko@sles15sp3
Last login: Fri Jul 16 10:56:54 2021 from

However, on the server pam_tally2 shows a login failure.

sles15sp3:~ # pam_tally2
Login           Failures Latest failure     From
geeko               1    07/16/21 10:57:16

When the user correctly logs in after the sixth attempt (matching deny=6 above), they get an error and locked account.

user1@server:~> ssh geeko@sles15sp3
Account locked due to 7 failed logins

The pam_tally2 command shows too many failed login attempts.

sles15sp3:~ # pam_tally2
Login           Failures Latest failure     From
geeko               7    07/16/21 10:59:50



By adding the following line to the /etc/pam.d/common-account file this problem will be resolved:

account    required
