Bug 1261750

Description of problem:
When setup authentication with LDAPPasswordIdentityProvider, will display a error:
# openshift start master --config=openshift.local.config/master/master-config.yaml
W0910 06:05:47.312265   13570 start_master.go:279] oauthConfig.identityProvider[0].provider.insecure: invalid value 'true', Details: validating passwords over an insecure connection could allow them to be intercepted
Invalid MasterConfig openshift.local.config/master/master-config.yaml
  oauthConfig.identityProvider[0].provider.attributes.id: invalid value '[]', Details: at least one id attribute is required (LDAP standard identity attribute is 'dn')

This is due to the PR(https://github.com/openshift/origin/pull/4264) change some config validation code.

How reproducible:
always

Steps to Reproduce:
1. Set up authentication with LDAPPasswordIdentityProvider as following:
  identityProviders:
  - challenge: true
    login: true
    name: "testldap"
    provider:
      apiVersion: v1
      attributes:
        email: null
        id:
        - dn
        name:
        - cn
        preferredUsername:
        - uid
      bindDN: "cn=read-only-admin,dc=example,dc=com"
      bindPassword: "password"
      ca: ""
      kind: LDAPPasswordIdentityProvider
      insecure: true
      url: "ldap://ldap.forumsys.com/dc=example,dc=com?uid"
 
2. Start openshift master with the config file
openshift start master --config=<PATH TO CONFIG>
3.

Actual results:
# openshift start master --config=openshift.local.config/master/master-config.yaml
W0910 06:05:47.312265   13570 start_master.go:279] oauthConfig.identityProvider[0].provider.insecure: invalid value 'true', Details: validating passwords over an insecure connection could allow them to be intercepted
Invalid MasterConfig openshift.local.config/master/master-config.yaml
  oauthConfig.identityProvider[0].provider.attributes.id: invalid value '[]', Details: at least one id attribute is required (LDAP standard identity attribute is 'dn')

Expected results:
Should work well
