Solaris Common Messages and Troubleshooting Guide

Cause

Many networking programs can print this message, including from(1B), lpr(1B), lprm(1B), mailx(1), rdist(1), sendmail(1M), talk(1), and rsh(1). The command prints this message when it cannot locate a password file entry for the current user. This error might occur if a user logged in just before the superuser deleted that user's password entry, or if the network naming service fails for a user who has no entry in the local password file.
