New F44 installation, OpenVPN log errors as:
May  9 20:26:39 ns openvpn[8]: PAM unable to dlopen(/usr/lib64/security/pam_lastlog2.so): /usr/lib64/security/pam_lastlog2.so: undefined symbol: pam_syslog
May  9 20:26:39 ns openvpn[8]: PAM adding faulty module: /usr/lib64/security/pam_lastlog2.so

May  9 20:26:40 ns openvpn[8]: PAM adding faulty module: /usr/lib64/security/pam_lastlog2.so


Reproducible: Always




Additional Information:
In bugreport form, is not possible select liblastlog2 package (where is /usr/lib64/security/pam_lastlog2.so ) - is not there oferred

Also, maybe same bug is reported in 2419509 and 2453457

Comment 1 Frank Lichtenheld 2026-05-11 15:30:52 UTC

Yeah, pretty clearly https://bugzilla.redhat.com/show_bug.cgi?id=2453457 describes the same issue, just with a different program loading the library. Will look into whether we need to do anything or if this is a bug in pam_lastlog2.so. I assume the latter, but not sure, yet.

Comment 2 Frank Lichtenheld 2026-05-11 17:14:30 UTC

Seems like a clear bug in pam_lastlog2.so. All other pam modules are linked against libpam.so. As described in the linked ticket this was probably hidden before by the callers having the symbols, but the linker settings seem much more aggressive in F44 so that did go away. Marking this as a duplicate.
