I have a server running OpenLDAP. When I start a ssh-session I can log in without problems, but an error appears in the logs. This only happens when I log in with a LDAP account (so not with a system account such as root). Any help to eliminate these errors would be much appreciated.

This error occurs because the pam_unix
module is asked to check the password of an LDAP user, and of course fails. This failure is then ignored by your PAM config, but the module logs it anyway (and this can't be disabled).
However, your config looks quite strange to me. You are using each of pam_unix
and pam_ldap
twice, and I suggest you to clean this up. If you use only their first occurrences, the error message should go away (because pam_unix
will be skipped for successfully authenticated LDAP users). However, I'm not sure what you wanted to achieve with the double checks and the pam_succeed_if
line, so please be sure you know what you do when changing this config.
