[Serusers] error: 400; check if you use aliases in SER

Hi, I am using ser 0.9.0 and ser is working with Mysql auth without problem. I can login with default user 'admin' and password 'heslo'. I received an error 'error: 400; check if you use aliases in SER' when I tried to use 'serctl add leonsun leonsun leonsun(a)mydomain.com'#39;. If I went to Mysql and inserted user and password into subscriber manually, I could use it to login. The funny thing is there is always this message whenever I input right or wrong password. [root@sip ser]# serctl add leonsun leonsun leonsun(a)mydomain.com MySql password: #any input whatever it's correct or not error: 400; check if you use aliases in SER Could anyone please advice? Thanks
