NIS Screen
1 minute read.
NIS is a client–server directory service protocol. Usage scenarios include the distribution of user and host names between networked computers. Use the Directory Services > NIS screen to configure Network Information Service on your TrueNAS.
NIS is limited in scalability and security. For modern networks, LDAP has replaced NIS.
