While I am at my upgrade, I also see that a PAM library is missing now:
PAM unable to dlopen(/lib64/security/pam_smbpass.so): /lib64/security/pam_smbpass.so: cannot open shared object file: No such file or directory net-fs/samba has been compiled with USE="pam", does someone know where to get that library from? # equery f samba | grep smbpa /usr/bin/smbpasswd /usr/lib64/samba/libsmbpasswdparser-samba4.so /usr/share/man/man5/smbpasswd.5.bz2 /usr/share/man/man8/smbpasswd.8.bz2 -> not included right now
