title: vSphere 5.1 authentication via external OpenLDAP
body: <p>I try to add OpenLdap authentication option to vSphere. I would like to give some users possibility to log in to vSphere using ldap accounts. So far I didn't found nothing. All tutorial in internet are for microsoft AD.
  So Im doing this:</p>
  
  <p>First login to vSphere-client using admin@SYSTEM-DOMAIN, select Sign-On and Discovery -> Configuration -> Add Identity Source</p>
  
  <p>After that I provide all basic info:</p>
  
  <p>name: ldap test</p>
  
  <p>primary server URL: ldap://ldap:389</p>
  
  <p>base DN for users: dc=ldap,dc=my_domain_here,dc=com</p>
  
  <p>When I click "test connection" Im getting this:</p>
  
  <pre><code>"probing for connectivity faild"
  </code></pre>
  
  <p>There is no problem with LDAP because I added LDAP auth to many other services, I just can't do that auth for vCenter.</p>
  
  <p>Maybe I dont understand the purpose of this feature in vSphere and maybe it's not possible to use user account from openLDAP to auth.
  Any ideas?</p>
