lssec Command

Purpose

Lists attributes in the security stanza files.

Syntax

lssec [ -c ] [ -f File ] [ -s Stanza ] [ -a Attribute ... ]

Description

The lssec command lists attributes stored in the security configuration stanza files. The following security configuration files contain attributes that you can specify with the Attribute parameter:

/etc/security/environ
/etc/security/group
/etc/security/lastlog
/etc/security/limits
/etc/security/login.cfg
/usr/lib/security/mkuser.default
/etc/security/passwd
/etc/security/portlog
/etc/security/user

When listing attributes in the /etc/security/environ, /etc/security/lastlog, /etc/security/limits, /etc/security/passwd, and /etc/security/user files, the stanza name specified by the Stanza parameter must be either a valid user name or default. When listing attributes in the /etc/security/group file, the stanza name specified by the Stanza parameter must be either a valid group name or default. When listing attributes in the /usr/lib/security/mkuser.default file, the Stanza parameter must be either admin or user. When listing attributes in the /etc/security/portlog file, the Stanza parameter must be a valid port name. When listing attributes in the /etc/security/login.cfg file, the Stanza parameter must be either a valid port name, a method name, or the usw attribute.

You cannot list the password attribute of the /etc/security/passwd file with the lssec command.

Only the root user or a user with PasswdAdmin authorization can list the lastupdate and flags attributes for administrative users.
