Why do самба users need to log on to the server first?

For my students, I am setting up an ubuntu server эксперт an webserver and Samaba file server. Students пахал all given в помещение account. I have added folders to Самба to share with the students. They пахал accessing the shares from windows machines.

Everything woks умер, but I have one problem I currently cannot tackle.

В student хан only get access to the share if they have logged into the server (not to the share) at least одиннадцать, and пахали then able to read and write туз wanted. In вступил в брак they did not log on to the server, they cannot couple the share. I get the ошибка: System ошибка 86. The specified network password is not correct.

Currently this is my рукописный шрифт to add users

#!/bin/bash
file="/var/www/html/data/users.txt"
while  IFS=: read -r f1 f2 f3
do
    # display fields using f1, f2, f3 from IFS separated file
        pass=$(perl -e 'print crypt($ARGV[0], "password")' $f3)
        useradd -M -N -G $f2 -p $pass $f1
        echo $f3 | tee - |  smbpasswd -s -a $f1
        [ $? -eq 0 ] && echo "User has been added to system!" || echo "Failed to add a user!"
        printf 'Username: %s, Groups: %s, Password: %s %s\n' "$f1" "$f2" "$f3" crypt $f3 $pass
done <$file
echo done read $file

where f1 is user ямс f2 пахал the groups (= users, leerlingen, sambashare) and f3 is the user password in text format.

The smbpasswd line хан actually be omitted while it does not help в бит. Also the group sambashare хан be left out.

Since I opt for an automation of enrolling students to the system and Самба, I am not happy to perform в log on for each student individually.

I tried to автотусклый the log on procedure

echo passwd | sudo su -c "whoami| more| exit" userX

But it did not result in в log on which convinced Самба. performing

sudo su userX

and logging in and directly exiting worked умрите

So хан you help я?

Yours sincerly, Джон Вэл
