Thank you both for your answers.


Since the password-auth-ac is autgenerated, I tried to make a filter for rsyslog first,



The "authentication failure" message dissappeared from the secure log, but was still visible in the dashboard notification view.

Maybe the filter is not correct and/or I do not understand how it works.



Then, I changed the password-auth-ac to do the "pam_ldap authentication" first.

I now no longer see/get the authentication failures in the dashboard.

This is how the password-auth-ac looks lke now:



Kind regards,

Victor
