When I check my Database (mysql) I find the following details :

mysql> select * from Users where EmailAddress like “%bvangoor%”\G
*************************** 1. row ***************************
id: 46061
* Name: myuser@cs.stonybrook.edu
bvangoor@cs.stonybrook.edu*
Password: NO-PASSWORD
Comments: NULL
Signature: NULL
EmailAddress: myuser@cs.stonybrook.edu bvangoor@cs.stonybrook.edu

Can anyone help me what the issue is.

RT Authentication works fine If I delete the user entry from
Database(mysql).

Thanks,
Bharath.
