Alternatives
Other alternative schemes for storing network information exist, such as the LDAP standard maintained by the IETF, including Microsoft’s LDAP implementation, Active Directory. LDAP can be configured to handle more general information, such as corporate employee structures, phone numbers, address, etc. so it requires more thought and planning. Many organizations require all the features of NIS+, LDAP, and Active Directory and run them all simultaneously.
Another alternative that has been popular in certain environments is the Hesiod name service, which is based on the DNS protocols.

Famous quotes containing the word alternatives:
“The literal alternatives to [abortion] are suicide, motherhood, and, some would add, madness. Consequently, there is some confusion, discomfort, and cynicism greeting efforts to “find” or “emphasize” or “identify” alternatives to abortion.”
—Connie J. Downey (b. 1934)
“Clearly, society has a tremendous stake in insisting on a woman’s natural fitness for the career of mother: the alternatives are all too expensive.”
—Ann Oakley (b. 1944)
“The last alternatives they face
Of face, without the life to save,
Being from all salvation weaned
A stag charged both at heel and head:
Who would come back is turned a fiend
Instructed by the fiery dead.”
—Allen Tate (1899–1979)
