NIS and Integrated Login Interoperability
NIS and Integrated Login Interoperability
NIS, Integrated Login, and DCE/DFS should interoperate without any
problems because they do not have any knowledge of one another.
Both Integrated Login and NIS attempt to solve the problem of creating a
common /etc/passwd and /etc/group file on multiple nodes. Integrated
Login does this by using /opt/dce/bin/passwd_export to pull the contents of
the DCE registry (basically the global /etc/passwd and /etc/group files)
onto each node. NIS, on the other hand, gets the global /etc/passwd and
/etc/group files through a hook in the getpwent() system call. DCE/DFS
uses this functionality primarily to print a username and group when you
perform an ls -l within DFS.
The second function of Integrated Login, which NIS does not provide, is to
obtain a user's DCE credentials when a user performs a standard UNIX login
through telnet, ftp, CDE, etc. If Integrated Login obtains the credentials
successfully, the user accesses DFS in an authenticated manner, and without
having to perform a dce_login. When DCE is not available, Integrated Login
fallsbacktousingthe/etc/passwd file; upon successful login, the user does
not have DCE credentials, gains unauthenticated access to DFS, and thus can
only access entries with an any_other ACL entry.
