Ajenti samba, issue setting user password

I have the same issue as this guy: https://ajenti.userecho.com/topic/305344-ajenti-an...
but the question was marked as answered. So I assumed that comments in it wouldn't get much attention.

I cannot set user passwords from the samba interface, but when using "sudo smbpasswd -a user" in the terminal, the password is set properly and I am able to use the share.
