Create a mail, FTP or database user
This program adds a new user to an existing virtual server. It is typically
called with parameters like :
virtualmin create-user --domain foo.com --user jimmy --pass smeg --quota 1024 --real "Jimmy Smith"
This command would add a user to the server I<foo.com> named I<jimmy> with password
I<smeg> and a disk quota of 1MB. The actual POP3 and FTP username may end up as
jimmy.foo, depending on whether or not domain suffix are always appended to
usernames, and what suffix format is used.
The C<--ftp> option can be used to give the new user an FTP login as well - by
default, he will only be given an email account. The C<--noemail> option turns
off the default email account, which is useful for creating FTP or
database-only users.
Extra email addresses for the new user can be specified with the C<--extra>
option, followed by an email address within the virtual server. This option
can be given multiple times if you wish.
The new user can be granted access to MySQL databases associated with the
virtual server with the C<--mysql> option, which must be followed by a database
name. This option can occur multiple times in order to grant access to more
than one database. Unfortunately, there is no way to grant access to
PostgreSQL databases.
To create a user who has only FTP access to the domain's website, use the
C<--web> flag. To turn off spam checking for the new user, include
C<--no-check-spam> on the command line. To add the user to additional secondary
Unix groups, the C<--group> flag followed by a group name can be given
multiple times.
For more control over the user's login abilities (FTP, SSH or email only),
use the C<--shell> parameter followed by a full path to a Unix shell, such
as C</usr/bin/scponly>. Available shells can be displayed using the
C<list-available-shells> command.
If you only have a pre-encrypted password that you want the new user
to use, the C<--encpass> flag can be used to set it instead of C<--pass>.
However, this will prevent Virtualmin from enabling MySQL access for the user,
as it needs to know the plaintext password to re-hash it for MySQL.
All mail users can have a password recovery address set, used by the forgotten
password feature in Virtualmin. For new users, this can be set with the
C<--recovery> flag followed by an address.
