These four programs all operate on the normal and shadow password and
|
|
group files: <filename>/etc/passwd</filename>,
|
|
<filename>/etc/group</filename>, <filename>/etc/shadow</filename>, and
|
|
<filename>/etc/gshadow</filename>.
|
|
</para>
|
|
|
|
<para>
|
|
Each program acquires the necessary locks before conversion.
|
|
<command>pwconv</command> and <command>grpconv</command> are similar.
|
|
First, entries in the shadowed file which don't exist in the main file
|
|
are removed. Then, shadowed entries which don't have `x' as the
|
|
password in the main file are updated. Any missing shadowed entries
|
|
are added. Finally, passwords in the main file are replaced with `x'.
|
|
These programs can be used for initial conversion as well to update
|
|
the shadowed file if the main file is edited by hand.
|
|
</para>
|
|
|
|
<para>
|
|
<command>pwconv</command> will use the values of <emphasis
|
|
remap='I'>PASS_MIN_DAYS</emphasis>, <emphasis
|
|
remap='I'>PASS_MAX_DAYS</emphasis>, and <emphasis
|
|
remap='I'>PASS_WARN_AGE</emphasis> from
|
|
<filename>/etc/login.defs</filename> when adding new entries to
|
|
<filename>/etc/shadow</filename>.
|
|
</para>
|
|
|
|
<para>
|
|
Likewise <command>pwunconv</command> and <command>grpunconv</command>
|
|
are similar. Passwords in the main file are updated from the shadowed
|
|
file. Entries which exist in the main file but not in the shadowed
|
|
file are left alone. Finally, the shadowed file is removed. Some
|
|
password aging information is lost by <command>pwunconv</command>. It
|
|
will convert what it can.

<para>
|
|
Errors in the password or group files (such as invalid or duplicate
|
|
entries) may cause these programs to loop forever or fail in other
|
|
strange ways. Please run <command>pwck</command> and
|
|
<command>grpck</command> to correct any such errors before converting
|
|
to or from shadow passwords or groups.
