How to configure LDAP for VPLEX?

I'm trying to configure LDAP authentication and it keeps failing, any help is appriciated:

Also can someone confirm that "Mapprincipal" is equivalent to "OU Search Path"?

VPlexcli:/> configuration configure-auth-service

  Configure Authentication Service Provider (Optional)

  You may select to use your existing LDAP or Active Directory as a directory service to

  authenticate VPLEX users. To configure this, you will need the authentication service

  provider server information, and the security information to map the users.

  Or, you may choose not to configure an authentication service provider at this time.

  You may configure an authentication service provider for authentication at any time,

  using VPLEX CLI commands.

  Would you like to configure an authentication service provider to authenticate VPLEX

  users? (yes/no) [no]: y

  VPLEX supports the following types of authentication service providers:

      1.  LDAP

      2.  AD

  Select the type of authentication service provider you would like use for VPLEX

  authentication. (1 - 2) [1]: 1

  Enter the Authentication Server IP Address []: xxx.xxx.x.xxx

  VPLEX supports these connections types:

      1.  SSL

      2.  TLS

  Select your connection type (1 - 2) [2]: 2

  Enter the port to be used for LDAP [389]: 389

  Configure Security Settings for Your Authentication Service Provider

  To configure the Authentication Service Provider you will need: the base disti

  name, the bind distinguished name, and the mapprincipal. Examples of these are

  Base Distinguished Name Example: dc=security,dc=orgName,dc=companyName,dc=com

  Bind Distinguished Name Example:

  cn=Administrator,dc=security,dc=orgName,dc=companyName,dc=com

  Mapprincipal Example: ou=people,dc=security,dc=orgName,dc=companyName,dc=com

  Enter the Base Distinguished Name []: PROD.XXXX.GOV

  Enter the Distinguished Bind Name []: CN=StorageSVC Service Account,OU=Applica - (I input correct DB Name)

                                                                                                                                                             

Enter the mapprincipal []: OU=Administrative,OU=UserAccounts,DC=PROD,DC=XXXX,                                                                             

DC=GOV

cstadmin: Object PAM VPLEX-PAM-Authority configured.

Enter StorageSVC Service Account's password:
