Ensuring Compatibility With +/- Syntax

If +/- is used in /etc/passwd, /etc/shadow, and /etc/group files, you need to modify the nsswitch.conf file to insure compatibility.

• NIS+. To provide +/- semantics with NIS+, change the passwd and groups sources to compat. Then, add a passwd_compat: nisplus entry to the nsswitch.conf file after the passwd or group entry as shown below.

  passwd: compat passwd_compat: nisplus group: compat group_compat: nisplus

  The above specifies that client routines obtain their network information from /etc files and NIS+ tables as indicated by the +/- entries in the files.

• NIS. To provide the same syntax as in the Sun Operating Environment 4.x release, change the passwd and groups sources to compat.

  passwd: compat group: compat

  Specifies the /etc files and NIS maps as indicated by the +/- entries in the files.

  Note –

  Users working on a client machine being served by an NIS+ server running in NIS compatibility mode cannot run ypcat on the netgroup table. Doing so gives you results as if the table were empty even if the table has entries.
