Bootstrap issue with Acegi

Hi All,
I am new to grails and came across this bootstrap issue with grails 1.0 and grails-acegi-0.2. The User object(s) in bootstrap fails to save on initialization but rest of the objects saves ok, not sure if there is anything wrong with code, I cannot see any errors even with hibernate, spring and acegi logging turned on. Details follow,

We have a plugin generated acegi classes out of which, User class looks like:

class User {
        static transients = ["pass"]
        static hasMany=[authorities:Role]
        static belongsTo = Role

        /** Username */
        String username
        /** User Real Name*/
        String userRealName
        /** MD5 Password */
        String passwd
        /** enabled */
        boolean enabled = false

        String email
        boolean email_show = false

        /** description */
        String description

        /** plain password to create a MD5 password */
        String pass="[secret]"

        static def constraints = {
                username(blank:false,unique:true)
                passwd(blank:false)
                enabled()
        }
}

and the bootstrap class looks like,

import org.apache.commons.codec.digest.DigestUtils as DU

class BootStrap {

    def init = { servletContext ->
       
        def pass = DU.md5Hex("pass")
       
        new User(username:"god",passwd:pass,enabled:true).save()
        new User(username:"admin",passwd:pass,enabled:true).save()
       
        new Role(username:"god",description:"Superuser",authority:"ROLE_SUPERUSER").save()
        new Role(username:"admin",description:"Administrator",authority:"ROLE_ADMINISTRATOR").save()
       
        new Requestmap(url:"/captcha/**",configAttribute:"ROLE_SUPERUSER").save()
        new Requestmap(url:"/register/**",configAttribute:"ROLE_ADMINISTRATOR").save()
     
    }
    def destroy = {
    }
}

Please help :)
