wrong user name is stored in mysql radacct table

[Zeli Kartzman]

we are running freeradius-1.0.5-1.2 and mysql-5.0.27-1.fc5
when i look at the radacct table in the mysql database i see there are a
number of entries with a non-existent user. i.e. 
D4JM4P61\\Kimberly Higgins

when i look at the radius.log file i see that the correct user name
appears and then the wrong one. why is the wrong one being stored in the
database?

radius.log
