Orts 3.2.7 with mysql.

We use mysql comandline to add customer to otrs . Auth by Radius.From time to time after registration by form (do by ourself) customer can't log to otrs,but next user who register later can do it.We can see that we have data in otrs db for this customer with problem .
The full warnafter use link http://<ip server >/otrs/customer.pl is " Authentication succesed,but no no Customer record is found in the backend."
In the Admin Dashboard for customer list i can see empty line betwen other customer registered after ot before this user.Waht more I can say that after 20h this record apear.
Do you have any sugestion ?
