#++ # NAME # nisplus_table 5 # SUMMARY # Postfix NIS+ client # SYNOPSIS # \fBpostmap -q "\fIstring\fB" "nisplus:[\fIname\fB=%s];\fIname.name.\fB"\fR # # \fBpostmap -q - "nisplus:[\fIname\fB=%s];\fIname.name.\fB"\fR <\fIinputfile\fR # DESCRIPTION # The Postfix mail system uses optional lookup tables. # These tables are usually in \fBdbm\fR or \fBdb\fR format. # Alternatively, lookup tables can be specified as NIS+ # databases. # # To find out what types of lookup tables your Postfix system # supports use the "\fBpostconf -m\fR" command. # # To test Postfix NIS+ lookup tables, use the "\fBpostmap -q\fR" # command as described in the SYNOPSIS above. # QUERY SYNTAX # .ad # .fi # Most of the NIS+ query is specified via the NIS+ map name. The # general format of a Postfix NIS+ map name is as follows: # # .fi # \fBnisplus:[\fIname\fB=%s];\fIname.name.name\fB.:\fIcolumn\fR # .fi # # Postfix NIS+ map names differ from what one normally # would use with commands such as \fBniscat\fR: # .IP \(bu # With each NIS+ table lookup, "\fB%s\fR" is replaced by a # version of the lookup string. There can be only one # "\fB%s\fR" instance in a Postfix NIS+ map name. # .IP \(bu # Postfix NIS+ map names use "\fB;\fR" instead of "\fB,\fR", # because the latter character is special in the Postfix # main.cf file. Postfix replaces "\fB;\fR" characters in # the map name by "\fB,\fR" before making NIS+ queries. # .IP \(bu # The ":\fIcolumn\fR" part in the NIS+ map name is not part # of the actual NIS+ query. Instead, it specifies the number # of the table column that provides the lookup result. When # no ":\fIcolumn\fR" is specified the first column (1) is used. # EXAMPLE # .ad # .fi # A NIS+ aliases map might be queried as follows: # # .nf # alias_maps = dbm:/etc/mail/aliases, # nisplus:[alias=%s];mail_aliases.org_dir.$mydomain.:1 # .fi # # This queries the local aliases file before the NIS+ file. # SEE ALSO # postmap(1), Postfix lookup table manager # README FILES # .ad # .fi # Use "\fBpostconf readme_directory\fR" or # "\fBpostconf html_directory\fR" to locate this information. # .na # .nf # DATABASE_README, Postfix lookup table overview # LICENSE # .ad # .fi # The Secure Mailer license must be distributed with this software. # AUTHOR(S) # Geoff Gibbs # UK-HGMP-RC # Hinxton # Cambridge # CB10 1SB, UK # # Adopted and adapted by: # Wietse Venema # IBM T.J.
