MPAD: The Organizational Unit (OU) structure is not being discovered. (4377875)

When setting up the Organization Unit for Directory Sync Pro for Active Directory, the customer is unable to see the Target Organizational Unit (OU) structure for selection. 

The Directory Sync Pro for Active Directory is unable to retrieve the domain name associated with the server entered under Connections > Target > Target Global Catalog. The error message "The LDAP server is unavailable" indicates that the tool is unable to establish a connection with the Global Catalog server to obtain the domain information.

Below are the steps to troubleshoot LDAP: 

1. Check LDAP Server Configuration:

   • Make sure that the correct Fully Qualified Domain Name (FQDN) or IP address of the LDAP/Global Catalog server is entered under Connections > Target > Target Global Catalog in the Directory Sync Pro configuration.
   • Ensure that the Global Catalog is running and properly configured on the Active Directory 

2. Credentials and Permissions:

   • Ensure the account credentials provided for the connection have sufficient permissions to access the Global Catalog server.
   • The user name and password is valid.
