admshadow(1M) DG/UX R4.11MU05 admshadow(1M)
NAME
admshadow - manage the shadow password feature.
SYNOPSIS
admshadow -o enable
admshadow -o disable
admshadow -o check [ -q ]
DESCRIPTION
The admshadow command is used to enable, disable or check the shadow
password feature. When the shadow password feature is enabled, the
standard /etc/passwd file will be split into 2 files: a new
/etc/passwd file which does not include encrypted passwords or aging
information, and an /etc/shadow file which includes the encrypted
passwords and aging fields. The permissions on the new /etc/passwd
file will continue to allow all users to read the file. The
/etc/shadow file will have permissions which allow only privileged
users to read and write the file.
Operations
enable This operation will enable the shadow password feature.
The standard /etc/passwd file will be split into a new
/etc/passwd file and an /etc/shadow file which will include
the encrypted passwords.
disable This operation will disable the shadow password feature.
The /etc/passwd and /etc/shadow files will be merged back
into a standard /etc/passwd file.
check This operation will check if the shadow password feature is
enabled or disabled. The message "enabled" or "disabled"
will be printed to stdout and an exit code of 0 or 11 will
be returned.
Options
-q Quiet mode. Do not print the "enabled" or "disabled"
message for the -o check option.
EXAMPLES
In the following examples, the system administrator performs the
following actions: enable the shadow password feature; disable the
shadow password feature; check if the shadow password feature is
enabled or disabled.
admshadow -o enable
admshadow -o disable
admshadow -o check
DIAGNOSTICS

/etc/shadow files.
Exit Codes
This section lists the possible exit codes and what they mean.
0 The operation was successful or the shadow password feature is
enabled (for the -o check operation).
1 The operation was unsuccessful.
2 The operation failed due to access restrictions.

NOTES
You must have appropriate privilege to perform the enable and disable
operations. On a generic DG/UX system, appropriate privilege is
granted by having an effective UID of 0 (root).
The shadow password feature is not intended to run on a system with
DG/UX information security. The admshadow enable operation will not
be available on these systems.
