Add some openLDAP attributes to ID token

[ihalloum]

Hello,
I am using openLDAP, DEX as OIDC provider and OAUTH2_Proxy as OIDC client.
I have added openLDAP connector to DEX with this configuration.
`
connectors:

• type: ldap
  name: OpenLDAP
  id: ldap
  config:
  host: 172.17.16.51:389
  insecureNoSSL: true

  bindDN: cn=main,dc=example,dc=com
  bindPW: "1234"

  usernamePrompt: Email Address

  userSearch:
  baseDN: ou=users,dc=example,dc=com
  filter: "(objectClass=person)"
  username: mail
  idAttr: DN
  emailAttr: mail
  nameAttr: cn

  groupSearch:
  baseDN: ou=groups,dc=example,dc=come
  filter: "(objectClass=groupOfNames)"
  userMatchers:
  - userAttr: DN
  groupAttr: member
  nameAttr: cn

`
But I have checked the ID token, it does not contain any user data. I need to include user full name, email, and groups on the ID token.
