Eu tenho tentado obter a autenticação LDAP e os diretórios iniciais exportados pelo NFS no CentOS 6 funcionando por alguns dias agora. Cheguei ao ponto em que agora posso fazer login na máquina cliente usando o nome de usuário e a senha no LDAP. No cliente, / home e / opt são montados no fstab sobre NFS. No entanto, todos os arquivos em / opt e / home são de propriedade de nobody:nobody (uid: 99, gid: 99) no cliente.
No entanto, meu uid e gid parecem estar definidos corretamente:
-bash-4.1$ id
uid=3000(myusername) gid=3000(employees) groups=3000(employees)
O que mais posso verificar? Aqui estão alguns arquivos de configuração no meu cliente:
/etc/nsswitch.conf

shadow: files sss
group: files sss
hosts: files dns
bootparams: nisplus [NOTFOUND=return] files
