namemap(3iac)

namemap -- map a name

Synopsis

cc [options] file -liaf

#include <iaf.h>

int namemap (char scheme, char g_name, char logname);

Description

The namemap routine is used to map remote names into local identities. It takes a remote user identification and the name of the ID mapping scheme as input and returns a corresponding local user login name. scheme is the scheme name, g_name is the remote (global) name, and logname is the location where namemap places the local login name.

To map the remote identity to a local one, namemap consults the uidata and idata map files associated with the scheme. When user-controlled mapping for a scheme is enabled by the system administrator, namemap consults uidata before idata, which causes user-specified entries to take precedence over system administrator mapping. If user-controlled mapping for the scheme is disabled, only the scheme's idata file is consulted.

Files

/etc/idmap/scheme_name/idata: map file for scheme_name
/etc/idmap/scheme_name/uidata: user-controlled map file for scheme_name
/etc/passwd: password file

Return values

Upon successful completion, namemap returns 0; otherwise, it returns -1.
