passwd.5

NAME

passwd - a table in the xCAT database.

SYNOPSIS

passwd Attributes: key, username, password, cryptmethod, authdomain, comments, disable

DESCRIPTION

Contains default userids and passwords for xCAT to access cluster components. In most cases, xCAT will also actually set the userid/password in the relevant component when it is being configured or installed. Userids/passwords for specific cluster components can be overidden in other tables, e.g. mpa, ipmi, ppchcp, etc.

passwd Attributes:

key

The type of component this user/pw is for. Valid values: blade (management module), ipmi (BMC), system (nodes), omapi (DHCP), hmc, ivm, cec, frame, switch.

username

The default userid for this type of component

password

The default password for this type of component. On Linux, a crypted form could be provided for the “system” component, which will be used during initial node provisioning. Hashes starting with $1$, $5$ and $6$ (md5, sha256 and sha512 respectively) are supported.

cryptmethod

Indicates the method to use to encrypt the password attribute. On AIX systems, if a value is provided for this attribute it indicates that the password attribute is encrypted. If the cryptmethod value is not set it indicates the password is a simple string value. On Linux systems, the cryptmethod can be set to md5, sha256 or sha512. If not set, sha256 will be used as default to encrypt plain-text passwords.

authdomain

The domain in which this entry has meaning, e.g. specifying different domain administrators per active directory domain

comments

Any user-written notes.

disable

Set to ‘yes’ or ‘1’ to comment out this row.
