Rails - Nov 2013 - how to store ldap data in ruby on rails application database?

i have created a web app with rails4 and authentication system is developed 
with devise_ldap_authenticable gem. where i am using username for login not 
email. but i want to store email in my users table. My user model is

 class User < ActiveRecord::Base

# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
#@attr_accessible :email, :password, :password_confirmation
# not required for LDAP :recoverable, :registerable, :validatable
devise :ldap_authenticatable, :rememberable, :trackable

validates_uniqueness_of :email, :allow_blank => true

 before_save :get_ldap_email

 def get_ldap_email
  self.email = Devise::LDAP::Adapter.get_ldap_param(self.username,
"mail")
 end
end 


But in users table of email field its storing data like

`email` = ''--- !ruby/array:Net::BER::BerIdentifiedArray\ninternal:\n-
!ruby/string:Net::BER::BerIdentifiedString\n str: !binary |-\n
cy5naG9zaEBzYW1zdW5nLmNvbQ==\n ber_identifier: 4\nivars:\n :@ber_identifier:
49\n''

log says, LDAP: Requested param mail has value
["s.ghosh-hcDgGtZH8xNBDgjK7y7TUQ@public.gmane.org"]

How i will store this value to my users table. where im doing wrong? please help
me out.

I have not used that, but I suspect that get_ldap_param is not
returning what you expect.  I suggest that you insert before the
self.email=... line something like
puts inspect Devise::LDAP::Adapter.get_ldap_param(self.username,
"mail")
which will show exactly what it returns, in the server window.
