problem login on moodle for joomla user

hi,
users joomla don't login to moodle
i upgraded to last version joomdle for moodle and joomla but it does not work.
any suggestions?
edit:
i try to replace in moodle/auth/joomdle/auth.php, function create_joomdle_user_record.
return $user;
with
return $newuser;
i try to register user and now in the > joomdle user< i have the situation of the added file

Moodle does no accept uppercase in usernames.

You should use the Joomdle user check plugin, to prevent that from happening.

thank you!
now the >Joomdle: Users< it's ok
but when i try to login on moodle there is still an error

An error? Which error?

when i try to login on moodle
<Invalid login, please try again>

my <Joomdle: System check> it's ok;
my user is registered on Joomla Account, Moodle Account and joomdle user in <Joomdle: Users>;

in <Site administration / ► Plugins / ► Web services / ► Manage tokens >the user for the joomdle service has Missing capabilities as in the image attached , i don't know if this capabilities are the reason of the error but if i want to add them there is nothing more to add in <► Site administration / ► Plugins / ► Web services / ► External services / ► Functions / ► Add functions>
edit: I found this capabilities in >► Site administration / ► Plugins / ► Web services / ► External services< edit "joomdle" in external service.

I may add the missing privileges?

any suggestions?

It seems you have added non-moodle functions to the Joomdle service.

You should delete the service, create it again, and only add Joomdle functions.

I have done but Moodle continues to deny access
when i try to login on moodle:
"Invalid login, please try again"

Try creating a new user, to see if you get the same problem.

Also, try enabling/disabling redirect less SSO in Joomdle config in Moodle.
