ypbind-mt is a multi-threaded implementation of a NIS binding daemon. ypbind-mt compiles and works on Linux with glibx 2.x (libc6). It should work on every System with POSIX threads and glibc 2.x. It works under Linux with libc5 and linuxthreads 0.7.1, but this C library isn't really thread safe and shouldn't be used with threads.
Ypldapd is a Network Information Service (NIS) server which uses LDAP as its information source. Using ypldapd, existing NIS clients can transparently use LDAP to resolve user, group and host information. Enterprises can thus realize the benefits of LDAP, such as its distribution and scalability, without ugprading clients. Used in conjunction with LDAP server technologies such as Netscape's Directory Server, ypldapd can provide single sign on to both NT and UNIX clients.
The Network Information Service (NIS) provides a simple network lookup service consisting of databases and processes. It was formerly known as Sun Yellow Pages (YP). The functionality of the two remains the same, only the name has changed. Its purpose is to provide information, that has to be known throughout the network, to all machines on the network.
