Comment 4 for bug 2002949

Hi Michal,

I can reproduce the issue by running the command shown below in P.S.,
where:
* bash shell variables username, current_password, new_password and ipaddress have been set to their correct values
* the current password of user "$username" ends with a '(' character.

Does this help ?

P.S.: step to reproduce the issue:

$ samba-tool user password --username="$username" --password="$current_password" --newpassword="$new_password" --ipaddress="$ipaddress"
