Grails Spring Security use email to login

Question

My User domain class extends SecUser. User has a property 'email'. Spring security uses SecUser's 'username' to login. I need to use 'email' to login. Is there a way to do this? Edit (from the accepted answer): I deleted SecUser's username property and added email property. Then I added this line to Config.groovy: grails.plugins.springsecurity.userLookup.usernamePropertyName = 'email'

Accepted Answer

RTFM my friend :)

http://grails-plugins.github.com/grails-spring-security-core/docs/manual/guide/single.html#4.1%20Person%20Class

```
userLookup.usernamePropertyName 'username'  User class username field
```

Add to Config.grooy:

```
grails.plugins.springsecurity.userLookup.usernamePropertyName='email'
```

newer versions of grails are using a prefix of

`grails.plugin.springsecurity` instead of `grails.plugins.springsecurity`

Grails Spring Security use email to login
