In my /etc/security/limits.conf I have
Code:
# grep ^[^#] /etc/security/limits.conf
* hard nofile 8192
sszb              soft    nofile          8192
sszb              hard    nofile          16384
fargred              soft    nofile          8192
fargred              hard    nofile          16384

I have shadow built with PAM support
Code:
# equery u shadow
[ Legend : U - final flag setting for installation]
[        : I - package is installed with flag     ]
[ Colors : set, unset                             ]
 * Found these USE flags for sys-apps/shadow-4.1.4.3:
 U I
 - - audit    : Enable support for sys-process/audit
 + + cracklib : Support for cracklib strong password checking
 + + nls      : Adds Native Language Support (using gettext - GNU locale utilities)
 + + pam      : Adds support for PAM (Pluggable Authentication Modules) - DANGEROUS to
                arbitrarily flip
 - - skey     : Enable S/Key (Single use password) authentication support

And the line about pam_limits.so has its place in every configuration file that may be at least related to logging in.
Code:
# grep -rHi pam_limits.so /etc/pam.d/*
/etc/pam.d/atd:session required        pam_limits.so
/etc/pam.d/login:session required pam_limits.so debug
/etc/pam.d/system-auth:session      required   pam_limits.so
/etc/pam.d/system-auth-winbind:session     required      pam_limits.so
/etc/pam.d/system-login:session required pam_limits.so debug
/etc/pam.d/system-services:session      required   pam_limits.so

But every time I log in
Code:
$ ulimit -n
1024

I’ve read this topic but in /var/log/messages pam_unix is the only pam-related strings that are present, and I’m in doubt if it’s actually working?

I'd suggest PAM debugging.
