== 3.16. How do I assign a single password to all subscribers in a list? ==

This scripting trick works for 2.x versions of Mailman, and relies on bin/withlist to work.

1) Become the "mailman" user, eg `su - mailman`.

2) Put the following small file "changeuserpw.py" in the bin subdirectory, making
sure that ~/bin is in user mailman's default path, so the file
can be found and used:

{{{
from Mailman.Errors import NotAMemberError

def changeuserpw(mlist, addr, newpasswd):

    try:
        mlist.setMemberPassword(addr, newpasswd)
        mlist.Save()

    except NotAMemberError:
        print 'No address matched:', addr
}}}

3) Create the following small shell script, named "change.userpw"
and make it executable (`chmod 700 change.userpw`):

{{{
#!/usr/bin/ksh

if [ $# -ne 2 ]; then

        print "Usage is: $0 list password"
        exit 1
else
        list=$1
        passwd=$2
fi

#---get the list members

list_members $list > /tmp/$list.members

#---change the user passwords

for member in `cat /tmp/$list.members`

do
        print "==== $member"
        withlist -l -r changeuserpw $list $member $passwd

done

rm /tmp/$list.members

}}}

4) Run the shell script to change all subscriber passwords in a specified list, eg:

{{{
change.userpw mylist foobar
}}}

will change the password for all subscribers in list "mylist" to foobar.

5) Check your work and check the status of the database files for the list. You should do a `check_db mylist` to see if you get any complaints (you should not). You should also do a dumpdb on the list's database file and take a look at it. You will find that all subscriber passwords in the database are what you specified for the shell script (if things worked). For example:

{{{

cd /web/data/mailman/lists/mylist

ls -l config.*

dumpdb config.pck > /tmp/mylist.dump

vi /tmp/mylist.dump
}}}

And then look for something like:

{{{
'passwords': { 'joeblow@somewhere.com': 'foobar',
}}}

and so on through all of your subscribers for that list. If all of the passwords are "foobar" then things worked.
