[Samba] Problem with libnss_winbind.so.2

[José Augusto Carvalho Filho]

Good afternoon people. Wiki'm following procedure:
RHEL based OSIf you have compiled Samba yourself on a RHEL based OS, to have your domain users and groups available locally on your Domain Member, you need to place two links in your /lib64 folder:# ln -s /usr/local/samba/lib/libnss_winbind.so /lib64# ln -s /lib64/libnss_winbind.so /lib64/libnss_winbind.so.2# ldconfig
But does not charge.
#ldconfig -v | grep winbind
ldconfig can't stat /libx32 no such file or directory ldconfig: Path `/usr/lib' given more than onceldconfig: Path `/usr/lib64' given more than onceldconfig can't stat /libx32 no such file or directory 

How can I fix my S.O. Centos 6.7.
Thank you!!!!
