[Fail2ban-users] Fail2Ban Pam-Generic does not work with PAM HTTP Basic Auth

[<mic...@fr...>]

Hello together,

I am using fail2ban on Raspbian Stretch Lite for SSHD and Nginx Basic-Auth. SSHD works fine for me,
but the default pam-generic Regex will not find entries like this:

Entry from /var/log/auth.log
Dec 21 11:32:19 raspberrypi ker process:pam_unix(nginx:auth): authentication failure; logname= uid=33 euid=33 tty= ruser= rhost=

I could use htpassw and the Nginx-Basic-Auth Filter but I have to use PAM and my Regex knowledge is too basic for this problem :(

I am looking for a filter like this:
http://txt2re.com/index-python.php3?s=Dec 21 11:32:19 raspberrypi ker process:pam_unix(nginx:auth): authentication failure; logname= uid=33 euid=33 tty= ruser= rhost=&-1&-8&-3
((nginx:auth))(authentication failure)

Thanks a lot for your help, best regards

Michael
