Estou tentando alterar a senha de uma conta NIS de um cliente Centos-7.0.1406 e o servidor é Centos-6.6
parece que o comando passwd não me pede para trocar a senha nem me pede senha antiga, ela só retorna o seguinte
Changing password for user mashour.
passwd: Authentication token manipulation error
aqui também é instantâneo strace
open("/usr/share/locale/en_US.UTF-8/LC_MESSAGES/Linux-PAM.mo", O_RDONLY) = 5
fstat(5, {st_mode=S_IFREG|0644, st_size=520, ...}) = 0
mmap(NULL, 520, PROT_READ, MAP_PRIVATE, 5, 0) = 0x7fa11e121000 close(5) = 0
open("/usr/share/locale/en_US.utf8/LC_MESSAGES/Linux-PAM.mo", O_RDONLY) = -1 ENOENT (No such file or directory)

exit_group(1) = ?
+++ exited with 1 +++
No entanto, posso alterar a senha da conta NIS de qualquer cliente Centos-6 usando o comando passwd.
Alguma idéia do que está errado?
